Public Ir Address Usage - Clarity C120 User Manual

C120 INTRODUCTION

Public IR Address Usage

public events where a infrared system is offered
for those with a hearing impairment. Examples of
such an area could be a movie theater, churches,
or public areas. Check with site administration to
see if infrared service is available.
C120 INSTALLATION
SETTING UP THE C120 TRANSMITTER
Important Setup Guidelines
The C120 TV Amplifier transmitter may be
placed on top of a television or shelf. Do not
place objects in between the transmitter base
and the headset receiver, as it will block the
signal to the headset.
It is important to read the following
guidelines to ensure the proper function
of your headset.
1. For the clearest signal, place the base at
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 where you

2. Sunlight can cause interference with the
product and cause problems such as buzz,
static, or hiss. As a result, this product cannot

televisions. from the base.
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.

C120 INSTALLATION
CONNECTING THE C120 TRANSMITTER
1. Connect the Power
Connect the AC Adapter into the DC12V port
located on the back of the base (Fig. 2). Plug the
AC Adapter into a wall outlet.
2. Select the Appropriate Audio Cord
A. RCA Cord: has red and white connectors
on both ends. Used to connect stereo TV's,
VCR's, or audio equipment to the C120 base
unit. See Figures 3 and 4.
B. RCA to 3.5mm Cord: has red and white
connectors on one end and a 3.5mm headset
plug on the other. Use this cord to connect
to audio devices that only have a headset jack.
See Figures 6 to 9 on page 9.
3. Configuring the Audio
A. RCA to RCA Mode
This is suggested for highest sound quality. This
mode should be used if the television (or other
audio equipment) has two RCA audio ports
(red and white). See Figures 3 and 4.
There are two types of ports on the back of a
television or other audio device, ones that receive
incoming sound, and others that transmit out-
going sound. The C120 needs to be plugged into
the ports that transmit the outgoing sound.
To find the correct ports on the back of the
television or other device, look on the back of
the device for the red and white ports that are
labeled "Audio Out." Most of the red and white
ports on the television are labeled "IN" for input,
and the C120 needs to be connected to a port
labeled "OUT" to receive the outgoing sound.

Note: The television is the
best solution because it is
a source for all the audio
from the DVD player, VCR,
cable, and other devices. For
example, if you plug into DVD
player, only audio from DVD's
will be heard.
