The TL7600 Headset does
not work at all.
The Headset is not getting
power from its battery.
 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 Headset LED will light to indicate
that the Headset is charging.
 If the battery is completely depleted, it can take up to 10
minutes to charge the battery enough for the Headset to
work even briefly. In this case, the ON/OFF LED will
remain off and you will not be able to use the device. After
10 minutes of 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 registration is not
working.
The Headset and the Deskset
are not communicating with
each other.
 Confirm that you have placed the Headset in the charger
before you press on the Deskset.
 If registration does not start, try lifting the Headset out of
the charger for a few seconds before placing it back.
