Changing Channels:

To change channels, simply depress the Toggle/Standby switch momentarily until the LED for the desired channel pattern is lit up. Remember to change the receiver channel as well, since it is not automatically changed when the transmitter channel is changed.

INTERFERENCE

If interference such as lines in the pictures is observed, changing the transmission

channel may cure the problem. In some cases strong signals from wireless network could cause the problem Also, AC generators in close proximity to the transmitter or receiver may cause lines

in the picture. Move the unit away from the source of the interference.

NO PICTURE

Check that the transmit and receive channels are set the same.

Verify all connectors are tight.

POOR PICTURE QUALITY

Raise transmitter and receiver antennas above ground and away from obstacles and

traffic, including foot traffic. Change the channel or check with a spectrum analyzer if any other source transmitting. Use only clear channel, not disturbed by other transmitting source.

Use an optional high-gain dish antenna on the receiver. Verify all connectors are tight. Shorten the receiver antenna feed cable.
