Code Selection

The push button unit generates random code sequences to which the chime unit is 

able to learn. Should your door chime unit activate intermittently for no apparent 

reason, the uncontrolled activation may be caused by another unit nearby or from a 

device operating on the same frequency.

Code/Push Button Limiting Switch

Your door chime unit is capable of working with 

a maximum of 4 Push Button units at 4 different 

frequency channels. If your door chime unit 

activate intermittently for no apparent reason, 

it might caused by a nearby device working 

on a similar frequency channel. To eliminate 

frequency channel interruption, Code/Bell 

Push Button Limiting Switch is to limit the Push 

Button unit and/or frequency channel that your 

door chime unit can be activated by. 
1.  Insert batteries into the Door Chime unit 

and press the Push Button unit once, the 

door chime will sound to indicate that 1st 

operating code is registered and memorized. 

This is the factory setting and intended to 

limit the activate frequency channel and Bell 

Push Button unit to 1.

2.  To register 2nd Bell Push Button operating code and/or frequency channel, Press 

and hold the code setting switch on the door chime unit for 1 second, it will give a 

“Beep” sound to indicate that door chime is ready to learn the 2nd operating code, 

press the 2nd Push Button unit once, the door chime will sound to indicate that 2nd 

operating code is registered and memorized. This will allow 2 different Push Button 

units and/or frequency channels working with the door chime at the same time.

3.  Repeat the same procedure for the 3rd and 4th Push Button units. The maximum 

amount of Push Button units and frequency channels that the door chime unit can 

be work at the same time are 4.

4.  To reset Code/Bell Push Button limiting function, remove batteries from the door 

chime for at least 10 seconds, and reinsert the batteries, this will reset the door 

chime unit to learn 1 Push Button unit and frequency channel only. 

NOTE: low battery in doo chime or push button unit will erase or rest the registered 

frequency channel between the door chime and push button unit, if the door chime 

unit does not sound when push button unit depressed, please replace batteries on 

door chime and push button unit, then set up both units again.

Resetting the Unit

To avoid uncontrolled activation:

1.  Switch off the Chime Unit for at least 1 minute.

2.  Switch back on. A double beep should be heard indicating that the unit is in 

learning mode.

3.  Press the Push Button. The chime should sound to indicate code selection.
