Adding and registering a headset
Registration options
The Marathon headset comes pre-registered to the headset base.
There are two registration options, as described below.
Option 1: You can register a previously deregistered Marathon
headset to your Marathon headset base (see page 19).
Option 2: You can deregister your Marathon headset (see page 21)
and then register it to an AT&T DECT 6.0 cordless
telephone (see page 20). You can register a maximum
of two headsets to a cordless telephone. The telephone
base recognizes and counts a headset the same as a
handset. When you register the headset to an AT&T
DECT 6.0 cordless telephone, the headset
base acts only as a charger for the headset. The
LIFTER AUDIO ADJUST, VOLUME / and MODE
controls on the headset base become inactive. You
can place the headset base anywhere you have an
available power outlet. Do not plug in the telephone
line cord; you only need to plug the headset base into
a power outlet.
Refer to your telephone user's manual for the
maximum number of handsets that you can register
to the telephone base. If you have the maximum
number of handsets registered, you need to follow the
deregistration information in your user's manual.
You can only register the headset to one product at a time, so
the headset must be deregistered before registering to a headset
base or a cordless telephone (see page 21).
