System Setup
Inserting Batteries
Door bell
1) Remove the battery compartment lid from the back of the doorbell.
2) Insert three LR6 (AA)/ 1.5V batteries supplied with the system, ensuring correct polarity
(+/-).
3) Carefully close the battery compartment again.
Bell push
1) Open the battery compartment on the back of the bell push.
2) Insert 23A/12V battery supplied with the system, ensuring correct battery polarity (+/-).
Leave the compartment open to be able to synchronize the radio frequency code in the
next step.
Synchronization (LEARN procedure)
This Doorbell is designed with the technology of Intelligent Code setting and Learning
function. It can generate up to 4096 different system codes by simple “LEARN” process
that there is no complicated setting of code switches and it will interference by other
remote control system is nearly impossible.
Note: LEARN procedure as described below must be performed before the wireless
doorbell function will work.
LEARN procedure:
1) When new batteries are inserted into the doorbell receiver, and it is selected at the
Ding Dong or Lighting + Ding Dong mode, the doorbell will initially sound.
2) Press “NEW CODE” button once to generate a unique system code, so that this set of
remote control will not be interfered by other similar systems nearby.
3) Press “LEARN” key on receiver while simultaneously pressing DOORBELL button on
the doorbell transmitter to synchronize the signals between the doorbell transmitter and
doorbell receiver.
4) Once the LEARN process is completed successfully, the doorbell will sound whenever
DOORBELL button is pressed.
Noted:
z Do not press the NEW CODE button of the transmitter again after synchronized
between the transmitter and the receiver unless you suspect that the Doorbell set is
interfered by other signals. This will generate a new system code, and then redo the
LEARN procedure again.
z To avoid interference
∼ do not put the doorbell receivers along side one another. A minimum distance of
18 inches (0.5 meter) is recommended.
∼ Do put the doorbell receiver and transmitter one meter above the ground level.
Setting the volume
Adjust the volume using the slide switch.
1 = low
2 = normal
3 = high
Note: If the ring is quieter than normal or sounds distorted, the batteries are either weak or
empty. Replace the batteries.
Choosing the signal
Note: Be sure to set the signal before mounting the bell push to the wall.
The signal selection switch allows you to set the following signals:
Chime only
Signal indicator blinks and chime is switched to silent
