Using a Cordless Device as a Remote Control
When not being used to talk, the cordless handset/headset buttons can act as a remote control
device to change display contrast, volume, and mute settings on the host IP phone. For
example, in a remote handsfree conference setting, you can use the Volume and Mute buttons
on a cordless device to adjust speaker levels and mute the microphone on an IP phone that is
not within his reach.
Alerting Tones and LEDs
The cordless devices provide the following alerting tones:
Low Battery Level
When the battery of a cordless device reaches a near-critical level, the IP phone displays a
warning. Until the battery is recharged (or until it becomes fully discharged), the warning is
repeated at each new call. To continue with a call while charging the cordless device, switch to
speakerphone and then cradle the cordless device.
Feature Function
Mute key on cordless device ON/OFF Two-pitch tone occurs immediately. Reminder tone
occurs 30 seconds after activation and then
regularly until deactivated
Mute key on phone ON/OFF No immediate tone. Reminder tone occurs 30
seconds after activation and then regularly until
deactivated.
Low battery (within 10 minutes left) Three beeps and 20 second pause repeated three
times.
Low battery (within 2 minutes left) Three rapid beeps and 1.5 second pause repeated
three times.
Out of range Repetitive 3-pitch tone until you are back in range.
NOTES
Audio indications are heard in the handset only when it is in use, and may interrupt
voice transmission.
If you are out of range for more than 10 seconds, any call that is in progress is
dropped and not recovered.
