Push Button Unit: Using the two holes of the back of push button as a template, mark the fixing

position for the unit. Drill hole and fit wall plug and secure the Push Button Unit with screws

(self-tapping 3 x 16mm screw) in position, or by the double-sided self-adhesive pad (included), onto

your front door or the position nearby.

Important: Mounting the Push Button unit on the UPVC doorframes or metal surface will

reduce the broadcasting range seriously.

battery compartment marked with “S”. Press the switch once, the melody will change to play the

next one on the list, there are total 8 melodies for selection. The Push Button is pre-set to

Digital Code Set Up The unit comes from the factory on a pre-set radio frequency digital code. However, should your door chime activate intermittently for no reason at all, it is possible that a similar unit is operating nearby on the same frequency digital code. The encoded frequency of the Push Button (transmitter) can be changed to avoid this problem. The Door Chime unit is equipped with advanced self-learning operation code ability therefore no setting is needed. 1.
