IMPORTANT:
• For adjusting the receiver, a completely plastic tuning screwdriver (including plastic blade) is needed. This is
supplied with the receiver.
• The transmitter must be in its housing with the cover on, and fitted with a new battery type V23GA or GP23A.
Check the polarity which is shown in the housing.
• The receiver may not be in the vicinity of any metal objects.
• The transmitter and receiver must have the same code.
1) Use of the new K6706A transmitter:
• Set the tuning capacitor CV1 of the receiver to around the middle of its adjustment range (see fig. 7).
Check that the tuning LED of the receiver is not lit up, 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.
• Activate the transmitter and very carefully turn the tuning capacitor CV1 on the receiver until the tuning LED
lights up. If all is well, one of the relays should now switch, if of course the codes of the transmitter and receiver
are the same.
• For more precise tuning, get someone else to activate the transmitter from a few meters away and then fine-
tune the receiver.
• Once the receiver has been set to a transmitter, then it will also be set for other transmitters of the K6706A type.
2) Use of the old K6706 transmitter:
• Remove capacitor C1 from the transmitter.
• Set the tuning capacitor CV1 of the receiver to around the middle of its adjustment range (see fig. 7).
Check that the tuning LED of the receiver is not lit up, 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.
