Using an Optional Headset
You can use a standard 2.5 mm telephone headset with your handset.
1) To install a headset, remove the headset jack cover and insert the headset plug into the
jack. You can do this with the phone in standby or during a call.
2) Just make and receive calls as usual, and plug in your headset to talk to the caller after
the call connects.
3) When you connect a headset, the handset automatically mutes the earpiece and
speaker. To re-activate the earpiece, just unplug the headset. To switch to speaker
handset, press Speaker.
Using the Voice Mail Waiting Indicator
When you have new messages, the STATUS LED turns green, red, or yellow, according to the
settings you selected in the LED signal menu. After you listen to all new messages, the
STATUS LED turns off.
Using the Security Menu
The Security menu lets you configure the keypad to automatically lock if the handset remains
idle and change the PIN used to deregister or reset the handset.
