Clarity A Division of Plantronics Inc. C120 Manual De Usuario

8

This mode should be used if the television 
(or other audio equipment) has only one audio 
RCA or a 3.5mm jack. 

This enables the C120™ to be used with 
computers, CD players, stereos, mp3 players, 
and other related products.

If the television, or other device, has only one 
RCA port, connect the left (white) RCA plug 
from the output into the left (white) RCA jack 
of the base. The right (red) jack should remain 
unplugged. See Figure 5.

If the television, or other device, has a 3.5mm 
jack, use the cord with the RCA jacks on one 
end and 3.5mm jack on the other. Plug the 
3.5mm into the device and plug the RCA jacks 
into the C120™ base. See Figures 6-9.

Next, select “Mono” on the Mono/Stereo 
switch.

Use this mode only if an RCA connection is not 
available. For example, older televisions do not 
have audio outputs.  In this case, the micro-
phone should be used. Connect the supplied 
microphone into the “Mic” jack on the back of 
the base, as illustrated in Figure 10. Place the 
microphone near the speaker of the television 
or stereo. 

Note: The microphone may pick up any sound 
in the room, such as speech, the doorbell, or 
the telephone. (Fig. 11)
