Troubleshooting
Corrective Action
Verify that the battery is installed and charged

correctly.
Place the Headset into the accessory charger.

Ensure the charger is securely plugged into an
outlet not controlled by a wall switch. The

If the battery is completely depleted, it can take

up to 10 minutes to charge the battery enough

charging, remove the Headset from the charger
and press ON/OFF on the Headset or HEADSET
on the Deskset to turn on the Headset.
Replace the Headset battery.


Headset out of the charger for a few seconds
before placing it back.


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 and/or contact your system
administrator.
