Interference
Because the 5.8 GHz frequency band is an unlicensed public access bands, there is
no control on other users. It is therefore possible that another user could be operating
on the same frequency in your area. If this is suspected, turn off the transmitter and
see if there is any activity on the LED’s of the receiver. If there is a transmission on
the same frequency the amber or green LED’s should light or flash indicating the
received signal.
If there are other users it may be possible to avoid interference by changing channels
or by repositioning the antenna. A directional antenna may also reduce the effect.
The reflected signal will show up as ghosting on the monitor. Occasionally this may
be seen in adverse weather conditions when a signal may be reflected from rain,
snow, dense cloud or fog.
Fault Finding Possible solution
No LED's illuminated Check power supply.
TX – 7 segment channel indicator should be on.
RX – 7 segment channel indicator should be on, plus
the first red LED of the signal strength meter
Venetian blind effect Incorrect voltage from power supply. Should be 12V on
–S versions
Low or no signal strength
Check video input on transmitter. See pages 5 and 13
regarding antenna height and position.
Snowy or grainy picture Weak signal. Check number of GREEN LED's on VRX
units signal strength meter. See pages 5 and 13
regarding antenna height and position.
Picture rolling or tearing Reflections. See page 13
Check output voltage from camera. Should be 1V p-p
