    Voice Mail Access

    Press red Touchlite™ Key
    Pressing any part of touch pad will dial out the correct number to access the voice mail system. Note: telephone must be off-hook on either handset or speakerphone first, before pressing the touch pad.



    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.No user adjustment of the date and time is available.

    Placing and answering calls

    To place or answer a call, first lift the handset or press the Speaker key. Then (if placing a call) use the dialing keys, or press any of the “user programmable keys” to “speed dial” a stored number. IN-USE will be displayed on the bottom, left and a small image of a handset will appear in the upper right of the LCD.

    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). When the call is disconnected properly, there will be no image of handset and IN_USE will no longer appear.

    Disconnect Function

    To activate the Disconnect feature, press the yellow Disc key when the conversation is complete. The Disconnect feature is a 2-second electronic timed line break used to automatically hang up a call and regain a new dial tone to establish a new call. This feature can be used with the handset or the speakerphone.


    To activate the speaker function, press the Speaker key, located directly below the speed dial keys. The light above the Speaker key will be steadily red; the LCD will display Speaker when active. In extremely noisy locations, it is better to use the handset.

    Mute Function

    To activate the Mute function, press the Mute key, located directly beneath the Flash key. When Mute is activated, the LCD will display MUTE. The Mute function disables the microphones in the handset and speakerphone.

    Data Port

    The jack on the bottom of the telephone (labeled DATA), next to the jack labeled LINE, 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.

    Visual Ringing/Message Waiting Indicator

    The red oval touch pad, with VoiceMail written below it, located directly above the dial pad, serves as a visual ringing indicator, message-waiting light, and also as a "speed dial" key for dialing the voice mail system to retrieve and listen to voice mail messages. When the phone is ringing, the light will flicker rapidly in cadence with audible ringer. When a voice mail message is waiting, the light will blink.

    Retrieving Voice Mail Messages

    The touch pad is programmed to dial the correct number to reach the voice mail system.
    To do so, follow these instructions:
    1) Lift handset or press Speaker to take telephone off-hook.
    2) Press the touch bar; pressing any part of touch pad will dial out the correct number to access the voice mail system. Note: telephone must be off-hook on either handset or speakerphone first, before pressing the touch pad.
    3) When the voice mail system answers and prompts for your password, enter it using the standard dialing keys.
    4) When finished listening to voice mail, replace handset in cradle or press Speaker key to hang up.

    Reviewing Caller ID Information

    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.

    Programming Speed Dial

    The Spectrum Plus™ has eleven (11) one-touch speed dial locations; two of which are pre-programmed for Transfer and Conference, and nine programmable one-touch keys used for speed dialing that are convenient for dialing frequently used telephone numbers.

    · Programming can be performed with the telephone on-hook only.
    · A maximum of 32-digits can be entered into ENTER NUMBER and
    12-characters into ENTER NAME.
