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.
Cordless Handset
The cordless handset, shown below provides office mobility, allowing you to place and answer
calls while away from your desk. Replacing the standard corded handset, the cordless handset
contains a chargeable battery that charges in the handset cradle when not in use. To use the
cordless handset, you must pair the handset with the IP phone. For more information, see
“Pairing the Cordless Module and Accessories” on “Pairing the Cordless Module and Devices”
on page 99.
