For this feature to operate correctly, several items must be set correctly. You must be subscribed to
Voice Mail from the telephone company. The message signaling must arrive on the correct line, and the
phone must be set for the correct type of message waiting. Message signals are sent by the Telephone
Company in one of two ways: FSK or stutter dial tone. Your telephone comes factory-set to FSK,
which means that only its FSK detector is active.
If your Message Waiting lamp does not flash when messages arrive, see Section 4.2 to modify the
configuration.
6.9. Flash
Press FLASH instead of pressing the hookswitch to activate services such as Call Waiting or 3-Way
Calling, or to activate certain PBX or Centrex features. You may be required to press other buttons
before or after you press FLASH. Refer to the custom calling instructions provided by your local
telephone company or to the operating instructions provided with your PBX.
The initial factory-set flash length is 600 milliseconds, which is appropriate for most installations.
However, you can adjust the flash length to make it longer or shorter. See Section 4.6. Flash may be
stored into a memory location. When a flash is stored, it is represented in the display by a small “f”.
6.10. Mute
The Mute feature allows you to turn off your telephone’s microphone so that the other party cannot
hear you. The Mute feature works with both the handset and the speakerphone. It silences only your
voice. The other party can still be heard. Mute automatically cancels when you hang up, switch
between lines or switch from speakerphone to handset during a call. To activate this feature, press
MUTE. The MUTE indicator will light. Press MUTE again to cancel the feature. The MUTE
indicator will turn off.
6.11. Do Not Disturb (DND)
While the DND feature is activated, your telephone will not ring. Incoming calls will be signaled only
by the LINE indicators flashing.
NOTE: Pages will not be heard through your telephone, and other stations will be unable to make
intercom calls to you or transfer calls to your telephone. You may still answer outside calls by pressing
the flashing LINE button. You may also place outside calls and intercom calls.
To activate DND
a. Press MENU. The display will read “Phone Setting”
b. Press the soft key under ENTER until “Do not Disturb:N” appears in the display.
c. Press the soft key under CHANGE. The display will now read “Do not Disturb:Y”.
d. Press MENU to exit.
The DND indicator in the display will now be on, and the display will read “Do Not Disturb.” To
cancel DND press the soft key under RESET
6.12. Line Reserve
The Line Reserve feature enables you to reserve a line that is currently in use. As soon as that line
becomes free, your phone will alert you with a triple ring and that line will be reserved for your station.
This feature is especially useful in offices where the phones are in heavy use.
