Replacing a headset

You may need to deregister your headsets if:

You have two registered headsets and need to replace one of them.

-OR-

You wish to change the designated headset number and/or the colors of the ON/OFF lights of your registered headsets.

You must first deregister both headsets, and then register each headset you wish to use again, one at a time.

Please read carefully through all the instructions before beginning the deregistration process.

To deregister all headsets from your TL7610/TL7611/TL7612 headset base

This procedure deregisters all the items registered to the headset base.

1.Press and hold PAIR on the TL7610/TL7611/TL7612 headset base until the MUTE light on the headset base turns on and starts to flash (at least 10 seconds), then release the PAIR button.

2.Immediately press and release PAIR again. You must press PAIR while the MUTE light is still flashing. (The light flashes for about seven seconds. If the light stops flashing, start again with step one above.)

3.Enter the following code on the headset by pressing the keys in this order: VOLUME /+, MUTE, VOLUME /–, MUTE, VOLUME /+, VOLUME /–, MUTE. When you see the MUTE light on the headset base turn off and the headset(s) ON/OFF light flashes twice every five seconds, the deregistration is successful. Repeat this step on the other headset if there is any.

4.To register the headset(s) to the headset base again, follow the registration instructions on page 10.

NOTES:

•If the deregistration process was not successful, you may need to reset the system and try again. Remove the headset from the headset base and press ON/OFF. Place the headset back into the headset base. You may also reset by unplugging the power from the headset base, then waiting a few seconds, and plugging it back in.

•You cannot deregister the headset(s) if another system headset is in use.
