5.8.2Resetting MSG Lamp

If your MSG lamp continues to flash after you have retrieved your messages, you may turn it off manually by followingthefollowinginstructions:

a.Press MENU. The display will read “Phone Setting”

b.Press the DOWN ARROW until “Message Lamp” appears in the display.

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 configu- ration.

5.9Flash

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”.

5.10Mute

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.

5.11Do 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.
