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 individually
register again each headset you wish to use.
Please read carefully through all the instructions on this page
before beginning the deregistration process.
To deregister all headsets and the dial pad (if applicable)

base including all headsets and the dial pad.
Press and hold

Immediately press and release

PAIR
while the
MUTE
light is still flashing. (The light flashes for about
seven seconds. If it stops flashing, start again with step 1 above.)
If the deregistration was successful:

light(s) flashes twice every 5 seconds.
• The dial pad (if applicable) displays
NOT REGISTERED

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, waiting a few seconds, then plugging it back in.
You cannot deregister the headset(s) and dial pad if another system headset
is in use.
