Frequently asked questions

I have no picture and no sound.
Check whether all the cables are connected properly.
The infra-red doesn't work.
a. Check whether the infra-red LED is placed on the sensor correctly.
b. Check whether all the cables are connected properly.
c. Check whether the LEDs on the transmitter and receiver flash up if the IR signal is
activated. You can alter the sensitivity of the receiver by setting the adjustment screw,
see tip 2.
d. The infra-red return channel only works if you are using amplifiers, splitters and
antenna boxes that support return channels. This is usually indicated by the term
'5-30MHz' or '5-68MHz'. Consult your cable store for more information.
e. Make sure the transmitter cannot control the receiver. The LEDs on the transmit-
ters have to be out of view of the LED on the receiver (acoustic feedback).
f. Make sure that, if you use multiple receivers, these do not all receive an IR signal
at the same time.
g. Prevent interference from other IR sources, such as sunlight, energy lamp
and/or plasma screen.
