C120TM OPERATION
Thank you for purchasing this new and exciting product from Clarity. The
C120™ provides an enjoyable television viewing experience for people who
have a hard time hearing the television.
The C120™ uses wireless infrared technology to send signals from the tele-
vision or other device to the headset receiver. This means that this product
can be used without the hassle or mess of cords.
The C120™ can be used with HDTV, Satellite, Digital, Plasma, LCD and
standard televisions. It can also be used to listen to other audio equipment,
such as a stereo. The use of the product eliminates the need to turn the
volume to extremely loud levels, without disturbing other viewers or others
in the area.
The C120™ not only can be used for enjoying at home, but can be used
outside the home in places like the movies, conventions, museum tours, and
sporting events (where a public infrared system is offered). Check with the
site administration to see if infrared service is available.
FEATURES
Clarity® Power ControlTM
The Clarity Power Control improves the quality of the incoming audio
signal from the television for a better listening and viewing experience. The
amplification of the television audio will be increased and the frequency band
from 2000 to 3000Hz will be specially enhanced to improve the clarity of
the television audio.
Telephone Ring Notification
This feature will notify the user of an incoming telephone call through the
C120™ Headset. An audible notification will be heard to notify the user that
the phone is ringing.
Public IR Address Usage
This feature allows the headset to be worn at public events where the
infrared system is offered to those with assisted listening devices. Examples
of these areas could be movies, churches and public speeches. Check with
the site administration to see if infrared service is available.

SETTING UP THE
C120™ TRANSMITTER
Important Setup Guidelines
The C120™ TV Listener transmitter may be
placed on top of a television or shelf. This
product uses infrared light. This type of signal
can be blocked by solid objects. Do not place
objects in between the transmitter base and
the headset receiver.
For the clearest signal, place the base at your
viewing eye level or above. As illustrated in
Fig.1, the clearest signal emitted from the
base is in a straight line, directly in front of
the base. The base must be clearly visible
from your television viewing position.
It is important to follow the above guidelines
to ensure communication between the base
and headset.
Sunlight can cause interference with the pro-
duct and cause problems such as buzz, static, or
hiss. As a result, this product cannot be placed
in direct sunlight or be used outdoors.
The headset will only receive the signal in the
same room where the base is located. The
maximum operating distance is approximately
38 feet, depending on environment.
Multiple headsets may be used with a single
base if they are set to the same frequency.
However, if more than one base is being used
at the same time, interference will occur.

C120TM OPERATION
CONNECTING THE TRANSMITTER
Power
First, connect the Power Supply into the DC12V
jack located on the back of the base. The DC12V
port is illustrated in Fig. 2. Then plug the Power
Supply into a wall outlet.
Audio
Next, using one of the Audio Cable supplied,
connect the base unit directly to the TV, VCR,
or other equipment output jacks. See different
connection options listed below.
Included in the package, there are two cords to
use for the incoming audio. One will have two
RCA jacks (red and white) on both ends. (Fig.
3) This can be used to connect with devices with
both Right and Left channel RCA jacks (TV’s,
VCR’s, etc). The other is a cord with two RCA
jacks (red and white) on one end and on the
other is a 3.5mm jack. (Fig. 4) A 3.5mm jack is
the size found on a pair of headphones. This can
be used to connect the C120™ to devices with
3.5mm ports, such as CD players, radios and
other small electronics. See Figures 6-9.
1. Stereo Mode:
(For Highest Sound Quality) This mode should
be used if the television (or other audio equip-
ment) has two RCA audio jacks (red and white).
See Figures 3 and 4.
Connect the RCA plugs from the speaker
output of the TV or VCR into both the left
and right RCA jacks on the base.
Next, select “Stereo” on the
Mono/Stereo switch.

C120TM OPERATION
2. Mono Mode:
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.
3. Microphone Mode:
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)

Telephone
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.
SETTING UP THE C120™ HEADSET
Installing the Batteries
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 Figure 14.
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.

The volume at which the product is set will
have an effect on battery life. At full volume,
the battery will last approximately four (4)
hours. Using lesser volumes will increase the
length of the charge. An indication that the
battery should be changed might be the sound
getting weak or noisy. The battery takes four
(4) hours to fully charge and can be charged
approximately five hundred (500) times before
it should be replaced.
Adjusting the Headset
On the top of the headset (receiver) there is a
switch labeled “Home/Away.” (Fig. 15) When
using the headset to listen to the television with
the included base, set switch to “Home.” For
use with public infrared systems, set the switch
to “Away.”
There is a volume control wheel on the top
of the headset where the volume can be con-
trolled easily while watching television. Turn the
wheel in the direction of the “+” to increase
volume and towards the “-” to decrease the
volume. (See Fig. 18 on page 11)
When the headset arms are extended, the unit
automatically powers on, as illustrated in
Fig. 16. When the headset is removed from
the head and the arms go back into original
position, the unit will power down. If there is
no audio signal being detected by the C120™
for one and a half minutes, it will power down.
Note: The infrared sensor that communicates
with the transmitter base is on the front of the
headset and should be pointed directly at the
base, as illustrated in Figure 17.

If the C120™ is producing no sound:
1. Ensure that proper installation and setup procedures were followed by
reading the user guide carefully.
2. Check to see if all the equipment is turned on, including the television
or VCR.
3. Look over all the cord connections (power, audio from television etc.),
making sure none have become loose or disconnected.
4. Ensure that the line of sight from the transmitter base to the headset
receiver is clear.
5. Check the battery in the C120™ Headset to see if it is fully charged.
6. Check to see if the infrared sensor on the base is facing the headset and
make sure the headset sensor is facing the base.
7. If the microphone is being used, try either turning up the television or
repositioning the microphone.
If the sound produced by the C120™ has static or is noisy:
1. If while in one mode (Stereo/Mono), static is experienced, switch the base
to the other mode.
2. Check the level of direct sunlight in the room. Too much direct sunlight
can cause interference.
3. Make sure the base is at the same height or above the level of the headset
when being worn.
Still Not Working?

Hearing Safety
The C120™ is designed to be used as an assisted listening device. This pro-
duct is intended to amplify sounds to a high volume. This means that damage
to hearing ability is a possibility if used improperly. To prevent any possible
hearing damage, please observe the following guidelines.
1. Turn the volume all the way down on the headset before putting it on.
2. When adjusting the volume to a comfortable level, start at the minimum
volume level then slowly turn the volume up. This will ensure the volume is
set at the minimum volume level needed to hear.
Medical Device Safety
Before using C120™ TV Listener in the area of a pacemaker or other medical
device, please consult a physician or the manufacturer of the medical device.
