Output acks
If your A/V com onent has only one set of A/V out ut jacks, and you
want to use it with a nearby TV, connect coaxial cable from the signal
OUT ort on the A/V com onent to the VHF/UHF IN ort on your TV.
In order to also view cable transmission on that TV, connect your
incoming cable TV source to the single IN ort of the A/V com onent.
Please see Fig. 5.

Note 1: On a NTSC system, the connector on the A/V equi ment is an
RCA jack. Connect the yellow lug to the jack labeled VIDEO, the red
lug to the jack labeled AUDIO RIGHT and the white lug to the jack
labeled AUDIO LEFT.
Note 2: If the A/V equi ment has only one out ut for audio (mono
sound only), connect the white lug to that single audio out ut jack.

RF Connection – for TV without A/V Input acks
If there is no A/V in ut jacks on your TV, you will need to get an RF
modulator (available at your local electronics store) to make the
connection between TV and receiver. See Fig. 8.
Connection through an A/V Component
If an A/V com onent (VCR, DVD layer, DBS receiver, and etc.) is
connected to the TV already, you can just connect the receiver to the
free LINE IN jacks on the A/V com onent. See Fig. 9.

Other Applications
Using Remote Control
The Wireless A/V Sender gives you the ability to control A/V com onents from
another room using your existing remote control device. To use this function,
follow the ste s below:
1. Place the transmitter next/close to the A/V source com onent and lug the
IR eye into the jack located on the rear of the transmitter (IR Eye lug).
Adhere the IR eye directly to the IR window on the front of the source
com onent (see Fig. 12) OR lace the IR eye in front of the source
com onent (see Fig. 13).

2. Position the receiver so that your remote control signal can strike the IR
window on the front of the receiver. Set the remote antenna on the
receiver straight. Do not bend the remote antenna.
3. To use your remote control, oint it at the front of the receiver and o erate it
as you normally would.

Trouble Shooting
If you are not getting any signal at all
• Check that the transmitter and receiver are ro erly connected to the A/V
com onents from which you want to send/receive the A/V signal.
• Make sure the transmitter and the receiver are turned on.
• Check ower switches on the remote TV and video source (VCR, DVD
layer, satellite receiver, etc).
• Make sure ower lugs are ushed all the way in.
• Check all cable connections.
• Check the CHANNEL switch on both transmitter and receiver are set to the
same number.
• If you connect the receiver to a TV through an RF modulator, check that the
TV is tuned to the same channel as the TV Channel switch on the RF
modulator (3 or 4).
If the signal is poor, or there is interference
• Adjust the transmitter by rotating orientations until you get the best rece tion.
• Change the channel on both transmitter and receiver and make them the
same.
• If there is a microwave oven in use in the ath between the transmitter and
receiver, remove the microwave oven or turn it off.
• Make sure the transmitter and receiver are within range of each other (range
of a roximately 300 feet; 100 meters in a clear line of sight).
Care and Maintenance
• Kee all its arts and accessories out of the reach of young children.
• Do not attem t to o en the case. Non-ex ert handling of the device may
damage it.
• Kee dry. Preci itation, humidity, and liquids, contain minerals that will
corrode electronic circuits.
• Do not use or store in dusty, dirty areas. Moving arts may be damaged.
• Do not store in hot areas. High tem eratures can shorten the life of
electronic devices and war or melt certain lastics.
• Do not store in very cold areas. When the A/V sender warms u (to its
normal tem erature), moisture can form inside the case, which may damage
electronic circuit boards.
