Troubleshooting
If you are not getting any signal at all
• Check that the transmitter and receiver are properly connected to the A/V
device from which you want to send/receive the A/V signal.
• Make sure the transmitter and the receiver are turned on.
• Check power switches on the remote TV and video source (VCR, DVD
player, satellite receiver, etc).
• Make sure power plugs are pushed 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 reception.
• Change the channel on both transmitter and receiver and make them the
same.

• If there is a microwave oven in use in the path 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 approximately 300 feet; 100 meters in a clear line of sight).
Care and Maintenance
• Keep all its parts and accessories out of the reach of young children.
• Do not attempt to open the case. Non-expert handling of the device may
damage it.
• Keep dry. Precipitation, humidity, and liquids, contain minerals that will
corrode electronic circuits.
• Do not use or store in dusty, dirty areas. Moving parts may be damaged.
• Do not store in hot areas. High temperatures can shorten the life of
electronic devices and warp or melt certain plastics.
• Do not store in very cold areas. When the A/V sender warms up (to its
normal temperature), moisture can form inside the case, which may damage
electronic circuit boards.
• Do not drop, knock, or shake it.
