The C120™ has the ability to produce an 
audible indicator heard through the headset 
when the telephone rings. The following 
step is necessary if telephone ring notification 
is desired. 

First, plug the telephone cord coming from 
the wall into the jack on the rear of the base 
labeled “LINE.” A phone cord can then be 
connected from the jack labeled “PHONE” 
on the rear of the base to a telephone. This 
process is illustrated in Figure 12.

The C120™ allows you to use the same 
phone wall outlet for both your phone and 
C120™ TV Listener.

The supplied battery is a NiNH battery. 
Install the supplied Rechargeable Battery 
into the bottom of the headset. Once you 
place the headset into the base, as illustrated 
in Fig. 13, it begins to charge the battery.

The main Headset Battery Charger and both 
backup batter chargers on the base have a 
corresponding LED light on the front panel 
that will light up when a dock is being used.

Backup batteries can be bought and placed 
in the additional charging docks located on 
the base. The charging docks are labeled 
in 

.

Having these extra batteries to switch in and 
out will enable longer product usage without 
having to wait for a battery to charge. When 
the product is not in use, return the headset 
to the base to recharge the battery.
