Probable Cause
The Headset is almost out of
range or is experiencing
interference.
Headset is in the charger or
powered down.
MUTE keys on Deskset and
Headset operate separately.
Headset cannot
communicate with Deskset.
Corrective Action
You may be close to being out of range. Try moving closer
to the Deskset.
Other electronic products can cause interference with
your Headset. Try installing the Deskset far away from
devices such as televisions, microwaves, or other cordless
devices.
If the problem persists, check audio quality on the
Deskset. If the Deskset audio quality is poor, refer to
"Resolving Audio Echoes" on page 241
Confirm that the Headset is out of its charger before you
press HEADSET.
Confirm that the Headset has sufficient power. If the
Headset does not respond and the blue light does not
blink, the battery may have no charge. Place the Headset
in the charger for at least six hours.
Only the MUTE key on the Headset mutes calls. The MUTE
key on the Deskset does not work with the Headset.
You may be out of range of the Deskset; move closer.
Verify that the Deskset can make outside calls. If it cannot,
then consult "Deskset Troubleshooting" on page
At the Deskset, confirm that your Headset is registered to
the Deskset. Press MENU –> User Settings –> Cordless
Settings. If the Headset is registered, the screen displays
2. Headset (Registered).
