TEST AND FINAL TUNING
IMPORTANT:
• A plastic screwdriver (including plastic blade) is needed to tune
the transmitter or receiver. This is supplied with the receiver.
• The transmitter must be in its housing with the cover off.
• The receiver may not be in the vicinity of any metal objects.
• The transmitter and receiver must have the same code.
• If it is to be operated from push button SW1 of the transmitter,
jumper CH1 of the receiver must be set. Otherwise, jumper
CH2 must be set for operation from push button SW2.
1) Tuning receiver:
• Set the tuning capacitor of the receiver to around the middle of
its adjustment range (see fig. 17 of the Receiver Handbook).
Check that the tuning LED of the receiver is not lit, or is just on
the verge of lighting up. If not, the tuning capacitor will have to
be adjusted a little. Do not touch the circuit with your hand.
2) Tuning one or more transmitters to the receiver:
• Activate the transmitter (do not touch any other parts other
than the push button) and then (very carefully) turn the tuning
capacitor until the tuning LED of the receiver lights up. If
everything is correct, the relays should now switch, if of course
the codes of the transmitter and receiver are the same.
• Now take the transmitter to a distance of about 10 metres from
the receiver and repeat the test. Then the transmitter can be
tested from around 20 metres (perhaps ask somebody to help
you).
• If the transmitter cannot be tuned to the receiver, then it might
be the case that the tuning capacitor of the receiver needs to
be adjusted.
Click the housing cover back into place.
