PLEASE NOTE: As of 3/06, STE-SD Analog phones are being replaced, for trouble calls or work order requests, with a slightly different model of phone since the original model is no longer available.

The information on the bottom of the newer model phone is: A little white sticker that has 5S-C Update 050506 DATE: 11/3/05; another sticker with the Series No. of ZX0407006627.

Some of the programming features, such as speed dialing are done differently than they are on the original phones. For the users guide for this phone, please consult the Aegis-55-c Telephone User Guide.

Setting Up Your Phone

Extension display

Your Lehigh extension number has been programmed to appear in the Caller ID LCD display whenever the telephone is idle. (If you ever need to reprogram it, please consult the instructions in the Troubleshooting section of this document.)

Changing contrast on the display screen

To adjust the contrast on the display screen, press the SPKR button so you hear dial tone. Press * * 0 0 2 # and the display will flash. It will then say "Contrast ?" with a number next to it. Press the 1 key and the contrast number will increase. (The contrast range extends from 0 to 7, 0 being light and 7 being the darkest.)

The display will flash back to its usual appearance for a moment to show you what the current contrast setting looks like, then the "Contrast?" setting will reappear. If you want to continue adjusting the contrast, press the 1 key again. The contrast will cycle from 7 back to 0 and up through the settings again as many times as you wish.

When you arrive at the contrast you prefer, press SPKR again to hang up the phone and save the preferred contrast setting.

Ringer volume

Ringer volume control is located at the rear of the telephone. Positions include: OFF LO HI. The “LO” ringer volume setting is recommended for most office users. "OFF" shuts off all audible ringing, but the neon lamp under the red touch bar will continue to flicker brightly whenever a call is received to provide a visual ringing indication. If the telephone is installed in a very noisy location, the “HI” ringer volume setting may be preferred.

Controlling listening volume during calls

To change handset receiver volume, press VOL key. There are three volume steps: normal, loud, and very loud. After the phone has been “on-hook” for a few seconds, the handset receiver volume automatically resets itself to "normal volume." Each of the first two presses of the VOL key raises the volume by one step. The third press of VOL resets it to "normal." This sequence then repeats as the VOL key is pressed: Normal, loud, very loud, back to normal, and repeat. Please Note: Please Note: According to our Scitec representative; in order to comply with ADA requirements, the volume cannot be "locked" on any one volume setting, it can only be modified on individual calls.

To change speakerphone volume, use the slide control on the right side of telephone. Sliding this knob towards the rear of telephone increases speaker volume. When using speakerphone, experiment with speaker volume control to obtain clearest sound with fewest interruptions. Speakerphone performance will vary from call to call. Sometimes a very small change of speaker volume will greatly improve intelligibility and reduce "dropouts" in hearing the distant party through the speaker.

Programmable speed-dial keys

There are 5 "user programmable" speed-dial keys, directly above the standard dialing keys, that can be programmed as the telephone user desires. You may enter frequently-called numbers, or perhaps telephone system features such as Call Pickup (*7) that you use often. (Please see the Features section below for a list of feature codes.) Each programmable memory key can hold up to 16 digits. Digits that can be stored include 0-9, *, #, FLASH, and PAUSE.

The speed dial keys may be programmed with the following sequence.

  1. Phone must be connected to a working analog telephone line.
  2. Remove both the plastic and paper faceplate overlays to expose the hidden keys, STORE and PAUSE, that are used for programming.
  3. Take phone off-hook, either on handset or speakerphone.
  4. Press STORE key.
  5. Dial key sequence to be stored. Key sequence may include digits 0-9, *, #, FLASH key, and PAUSE key, up to a total of 16 keys.
  6. If needed, each PAUSE inserts a 3.6 second pause before the next digit is dialed out. PAUSE may be entered multiple times to create longer pause periods.
  7. Press destination key that entire key sequence is to be stored into.
  8. Repeat steps 4, 5, 6, and 7 for each programmable key to be programmed. Then hang up.
  9. Test your programming by taking phone off-hook, and pressing ONE newly programmed key. Observe that the correct number is dialed out, and/or the desired telephone system feature is properly activated. Then hang up and repeat until all programmed keys have been checked for proper operation, one at a time.

Telephone Operation

Placing and answering calls

To place or answer a call, first lift the handset or press the SPKR key. Then (if placing a call) use the dialing keys, or press any of the “user programmable keys” to “speed dial” a stored number.

Hanging up calls

To hang up a call, replace the handset in the cradle (or press SPKR if your call took place on the speakerphone). Please note that it may take several seconds for the call to disconnect properly! If you try to pick up the line again too quickly after disconnecting from the previous call, you may hear the call still continuing, or you may hear the announcement "enter, enter" from the system. This is not a problem - it just means you need to allow more time. There's an easy way to tell if your call has disconnected properly - simply look at your display screen. In the upper right-hand corner is a small image of a handset. The handset will light up when you place a call; it will disappear as soon as the call has been disconnected properly.


Each press of the SPKR key toggles speakerphone mode on or off. The “SPKR LED”, located immediately ABOVE the SPKR key, indicates speakerphone mode status. Whenever “SPKR LED” is on, speakerphone mode is enabled. Note that speakerphone mode can be turned on or off at any time by pressing SPKR key, even while handset is off-hook during a call.
SPKR key operation while handset is in cradle:

To answer or dial a call using the speakerphone, press SPKR key while handset is in cradle. The LED light above the SPKR key will light up, speaker will turn on, and phone will go "off-hook." Dial or talk normally. To end a speakerphone call, press SPKR again. The SPKR LED light will turn off, and phone will hang up. To switch from speakerphone to handset at any time during a call, simply lift the handset. Note that the SPKR LED will shut off at this time. If the handset is replaced in the cradle while the SPKR LED light is off, the phone will hang up, and your call will end. To switch from handset back to speakerphone without hanging up, first press SPKR. The SPKR LED light will turn on. Then replace handset in cradle, and continue the call on speakerphone.
SPKR key operation while handset is out of cradle:

If the SPKR LED light is on, returning handset to cradle will switch the current phone call over to the speakerphone. If the SPKR LED is off, returning handset to cradle will hang up on the current call.
Tips on using the speakerphone:

The speakerphone is a “half-duplex” speakerphone. This means it is possible to either talk or listen over the speakerphone, but not both at the same time. Avoid speaking while the distant party is talking. Position the phone within arms length and with the small microphone hole on the front of the phone facing the telephone user. Do not cover up the microphone hole, on the front of the telephone, while using the speakerphone. In extremely noisy locations, it is better to use the handset.
Usage of MUTE key:

The MUTE key controls the microphones in both speakerphone and handset. Each press of MUTE toggles the microphones and the MUTE LED light (located immediately above MUTE key) on or off. Whenever the MUTE LED light is illuminated, all microphones are OFF, and you will be able to hear the party at the other end of your call, but they will not be able to hear you.

MUTE is particularly useful for listening to prompts, voice mail, and other incoming audio while on speakerphone. This speakerphone is half-duplex. As with all half duplex speakerphones, this means it can sometimes be hard to hear the distant party over the speakerphone if the phone itself is in a noisy environment. This happens because any local background noises picked up by the telephone may interrupt the incoming sound. But by placing the phone in MUTE mode, even weak sounds from the distant party can still be heard clearly in the speakerphone without any interruption.

Touch bar

The red touch bar at the very front of the telephone serves as a visual ringing indicator, message-waiting light, and also as a "speed dial" key for dialing a voice mail system to retrieve and listen to voice mail messages.

Visual ringing indicator

The touch bar will flicker rapidly in cadence with the audible ringer whenever the telephone rings. Even if the audible ringer is switched off, this visual ringing indicator will still light up whenever telephone receives a “ringing” signal.

Message Waiting indicator

The touch bar will either light up steadily or blink slowly whenever a voice-mail message is waiting for the telephone user. The message-waiting indicator only operates while the telephone is "on-hook." Please consult the Scitec update page for information regarding the message waiting indicator.
Retrieving voice mail messages

The touch bar is programmed to dial the correct number to reach the voice mail system. To do so, follow these instructions:

  1. Either lift handset or press SPKR to take telephone off-hook.
  2. Press the touch bar Pressing any part of touch bar will dial out the correct number to access the voice mail system.
  3. Note: telephone must be off-hook on either handset or speakerphone first, before pressing the touch bar.
  4. When the voice mail system answers and prompts for your password, enter it using the standard dialing keys.
  5. When finished listening to voice mail, replace handset in cradle or press SPKR to hang up.

Telephone Features

To use feature keys and programmable speed-dial keys, first take telephone off-hook by either lifting handset or pressing SPKR. Then, press the desired feature or speed-dial key.

Note: The FLASH key may used to access certain telephone “system” features. It has the same effect as “tapping” the switch hook. FLASH may be stored in programmable speed-dial memory keys, along with other digits.

Display and Caller ID Operation

The name and number of incoming callers can be viewed for both internal and external calls.

For external calls, the number will appear first. Please note that if the calling party information is blocked or not available, the name will appear as OUT OF AREA, Unavailable or Private.

For internal calls, the caller's name will appear first. Please note that if names are not available through our telephone system, (i.e. house phones, student phones), the number alone will appear.

Up to three lines of information are displayed by the Caller ID unit. When the phone is idle, the current date and time appear on the top line. On the left hand side of the middle line, two digits show the number of NEW calls received since the last time Caller ID information was reviewed. On the right hand side of the middle line, the telephone's local extension number appears. The bottom display line is blank while the telephone is idle.

When the telephone rings and Caller ID information is received, the display then shows the date and time of the incoming call in the top line. The Caller ID information will be displayed between the first and second ring of the incoming call. The "CALL#" of this call in the internal Caller ID memory bank appears on the left side of the middle line, and the new caller's telephone number appears at the right side of the middle line; the bottom line will display the new caller's name. Whether or not the incoming call is answered, this information will be displayed for 45 seconds, and then display will automatically revert back to the "idle mode" display. The number of "NEW" calls tallied in the idle display will have increased by one.

There are 60 Caller IDmemory locations. When the telephone is first used, or after the Caller IDmemory has been completely erased by using the DEL key, the very first call received will have its Caller ID information stored in location "CALL# 01." Each time another new call comes in, it is stored in the next higher Caller ID memory bank location. The highest Caller ID memory position is 60. When the 61st call is received, the contents of the oldest call in Caller ID memory location "CALL# 01" are permanently lost, and all previously stored Caller ID information is moved down by one "CALL#."

Reviewing Caller ID information

When the display is in the idle state, press any of the three Caller ID function keys: DOWN or UP (on the Caller ID rocker key just below the dial pad), or DEL, just to the right of the DOWN-UP rocker key. Briefly pressing any one of these three keys will bring up a display of the date, time, CALL# in memory, telephone number, and name (if available) of the most recent caller. To scroll through other previous calls, press the DOWN side of the rocker key. Each press of DOWN goes back one call in the memory bank. The oldest call in Caller ID memory is "CALL# 01," and the highest "CALL#" is the most recent call. The Caller ID memory wraps around, so after displaying the most recent call (the highest CALL#), the next CALL# displayed by pressing UP will be "CALL# 01," the oldest call in memory. DOWN and UP can be freely used to scroll back and forth through all the stored Caller ID memory slots. The date and time each call was received are shown. If none of the three keys DOWN, UP, or DEL have been pressed for 45 seconds, the display reverts back to the idle mode. The number of "NEW" calls automatically resets to "00" after reviewing any stored Caller ID information, whether or not all previously received calls have been viewed.

Deleting stored Caller ID information

The contents of any single Caller ID memory bank location can be erased by briefly pressing the DEL key while the "CALL#" to be deleted is displayed. The prompt "DELETE?" will then appear in the bottom line of the display. Pressing DEL again permanently deletes the selected Caller ID record. To cancel the delete operation while the "DELETE?" prompt is displayed, press DOWN or UP instead of DEL, and the selected record stays in the memory. Whenever a single CALL# slot is erased, any stored calls in memory with higher CALL# than the one just erased will all be moved down by one CALL#

To erase ALL STORED Caller ID information at once, first use DOWN or UP to display any stored Caller ID memory. Then press and hold the DEL down steadily for several seconds, without releasing it. The prompt "DELETE ALL?" will appear. Pressing DEL a second time completely clears ALL Caller ID information from the internal memories. To cancel deletion of all calls, press DOWN or UP in response to the "DELETE ALL?" prompt.

After deleting all calls, the message EMPTY LIST will appear in the display. After 45 seconds, the display will revert back to the idle mode.

Date and time display

The date and time display is automatically reset to the correct date and time each time the telephone receives a new Caller ID call. No user adjustment of the date and time is available. If the phone is disconnected from an active telephone line, the date and time will stop advancing, and when power is restored, the display will be "slow" by the length of time the phone was disconnected from an active phone line. It is normal for the time display to run slightly fast or slow over a long period of time if the telephone does not receive any new calls with Caller ID. This is not an indication of a problem with the telephone. This is due only to the limitations of using the telephone line itself as the power source for the clock and Caller ID unit inside the telephone. As long as the telephone receives at least one incoming Caller ID call per 24 hour period, the date and time display will remain accurate to within 1 minute.

Programming Lehigh extension number display

Your Lehigh extension number has been programmed to appear in the Caller ID LCD display whenever the telephone is idle. If you need to re-enter your extension number, follow these steps.

  1. Telephone must be connected to a working analog telephone line.
  2. Remove faceplate overlays to expose the hidden programming keys. Overlays are attached to telephone by four small tabs on their sides.
  3. Press SET, and hold it down steadily for approximately 2 seconds. LCD display will "blank out" except for a "0" on the right hand side.
  4. Press the DOWN and/or UP key repeatedly to scroll through the numbers 0-9, " " (blank or space), and "-" (dash).
  5. When the LCD display shows the correct first digit of the user’s local extension number, briefly press SET.
  6. The displayed number will shift one digit position to the left.
  7. Again, use DOWN and UP, followed by SET to continue entering the local extension number. Up to 12 digits total, including “ ” (blank or space) and “-“ (dash), may be entered.
  8. Errors may be corrected by pressing DEL. Each press of DEL backspaces the displayed number by one digit position.
  9. When the entire local extension number is correctly displayed, press and steadily hold down SET for approximately two seconds. When the bottom line of the display prompts “SAVED IN MEMORY,” release SET key.
  10. If speed dial keys are to be programmed or re-programmed at this time, continue with the steps listed below. If finished, replace the faceplate overlays. Carefully place all four tabs on faceplates into the 4 retaining slots on the telephone body.

In case of trouble with Caller ID and programmable keys

Caller ID information is transferred into the telephone between the first and second ring. If you answer the telephone on the very first ring, the Caller ID information for the new call will not be displayed or stored in memory.

Caller ID memory and programmable speed-dial key memory contents are both protected against accidental loss due to disconnecting the telephone from the telephone line, or by the telephone system itself experiencing a power failure.

On rare occasions, a power surge or extremely high static electricity discharges near the telephone may cause the telephone to "lock-up." If this happens, Caller ID information displayed may appear scrambled, or some of the telephone’s feature keys may become temporarily inoperative. To reset, simply disconnect the telephone from the external phone line for approximately 20 seconds by unplugging the modular cord at the rear of the telephone, and then reconnecting the cord. This will reset the Caller ID display. All Caller ID information previously stored in the telephone will be restored and can then be viewed again by using the DOWN and UP keys. However, the Caller ID memory may not contain records of any calls received while the telephone was "locked up."

Also, the telephone’s “programmable” speed-dial keys may sometimes need to be re-programmed following exposure to excessive levels of static electricity. Should this happen, please reduce static electricity levels near the telephone by spraying “anti-static” spray on nearby carpets, chair mats, and upholstery. Then follow the instructions above to re-program the "programmable" keys.

Data Port

The jack on the right side of the telephone (labeled DATA), next to the speaker volume control slider, may optionally be used to connect a computer modem, credit card terminal, or other similar accessory device directly to the telephone line. Note that the telephone and the device plugged into DATA jack cannot both be “off-hook” at the same time, as both the telephone and the DATA jack share the same telephone line.

Do not attempt to use the data port for connecting the handset to the telephone or for connecting the telephone to the jack on the wall. The data port is ONLY to be used for connecting modems, computer fax/modem boards or similar accessory devices.
