Make sure all connections are made properly (following this manual) and all
devices are switched on.
• Make sure the same channel is set on receiver and transmitter.
• In case of S-video, make sure the mode on the TV is set correctly (refer to
the user manual of the TV).
Interference/noise
•
Adjust antenna direction of receiver and transmitter for optimal performance.
• Make sure the adaptor input voltage is > 220 VAC.
• Select different channel (on both receiver and transmitter!).
• Change position of the receiver and/or transmitter.
• When transmitter and receiver are < 10 m apart, do not unfold the antennas.
• Switch off microwave ovens.
Remote control doesn’t work

Aim the remote control towards the receiver (see [8]) and press and hold the
button for ±1 second.
• Make sure the IR LEDs are pointing towards the sensor(s) of the transmitting
