Getting started

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 color of the ON/OFF lights of your registered headsets.

You must first deregister both headsets, and then register again each headset you wish to use individually.

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

To deregister all headsets

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

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

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 it 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 turns 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.

To register the headset(s) to the headset base again, see page 19.

NOTES:

•If the deregistration process failed, 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.
