ADJUST ONLY THIS RECEIVER
From one receiver, the jumpers J1 and J2 must be cut, this
receiver must not be adjusted with the transmitter.
22. About the housing
The circuit can also be installed in a plastic housing (NOT A METAL
BOX) e.g. WCAH2851.
Place the housing in a place where there are few metal parts. It may
be the case that after installation, the circuit will have to be retuned.
This is because of the influence of metal parts in the vicinity of the
circuit.
