Test & set-up
• The transmitter must be in its housing with the cover off.
• Activate the transmitter (do not touch any other parts other than the push button) and then very carefully turn
the tuning capacitor CV on the transmitter until the tuning LED of the receiver 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, activate the transmitter from a few meters away and then fine-tune the transmitter.
3) Use of a new K6706A transmitter together with an old K6706 transmitter:
• Do the receiver set-up and adjustment as in point 1 together with the new transmitter type K6706A.
• When using the old K6706 transmitter type, capacitor C1 of the transmitter must be removed.
• The transmitter must be in its housing with the cover off.
• Activate the transmitter (do not touch any other parts other than the push button) and then very carefully turn
the tuning capacitor CV on the transmitter until the tuning LED of the receiver 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, activate the transmitter from a few meters away and then fine-tune the transmitter.
If the transmitter cannot be tuned to the receiver, then it might be that the tuning capacitor of the
receiver needs to be adjusted.
REMARK: When a new receiver K6727 is used in conjunction with a one channel receiver K6707, then on
the K6707 capacitor C1 must be a 1pF type.
