Deregistering a headset
If you want to register your Marathon headset to an AT&T DECT
6.0 cordless phone, you need to deregister your headset from
your Marathon headset base first.
Please read carefully through all the instructions on this page
before beginning the deregistration process.
To deregister the headset from 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.
Immediately press and release PAIR again. You must press PAIR
2.
while the MUTE light is still flashing. (The light flashes for about
seven seconds. If it stops flashing, start again with Step 1).
When you see the MUTE light on the headset base turn off and
the headset ON/OFF light flashes twice every five seconds, the
deregistration is successful.
To register the headset 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.
•
To deregister all headsets from an AT&T DECT cordless telephone base, see
the user's manual of your cordless telephone system.
