Product Overview

The wireless Doorbell uses radio frequency (RF) technology to activate a separate door chime unit, with the
Doorbell acting as the transmitter (once fitted) and the door chime unit as the receiver. There are over 250 RF
channels that the Doorbell and door chime unit can operate on and the units come supplied with a standard
factory default channel setting. Channel settings can easily be changed and further details on this can be
found in the Channel Set up section.

The Doorbell has been designed to be attached to the outside of the designated entrance with the supplied
transmitter wired into it from the inside. By pressing the button on the outside Doorbell, the Doorbell transmits
the signal to the door chime receiver and the chime will activate.

Please read and follow the instructions below before attempting to activate or install your Doorbell and door
chime. It is recommended that you retain a copy of these instructions for future use.

Initial Set up Instructions

1. Check contents of pack and ensure all components listed are present. Contact your suppliers if anything
is missing.

2. Before permanently fitting the Doorbell and door chime unit into place, first test the system. Wire the
transmitter into the back of the Doorbell by attaching the positive white wire to terminal A and the grey
wire to terminal C (ensuring the correct polarity). Then activate the battery in the transmitter by removing
the battery pull out tag located on the side of the unit and then insert the supplied batteries into the door
chime (please see To fit or replace batteries below). Please note the battery in the transmitter should

be activated before inserting the batteries into the door chime. With the batteries activated, this enables

the pairing of the system. A double beep will be heard to indicate a successful pairing. At this point press
the button on the Doorbell within 30 seconds to confirm activation.

3. With a successful pairing of the two devices, you may proceed with the fitting of the Doorbell and door
chime units as described (please see Doorbell & Transmitter Fitting Instructions below). Remember
you will need to remove the wires from the Doorbell terminals A & C and reattach them to the Doorbell
when permanently fitting the device into place.

4. Should the units not pair, please remove the batteries from the door chime for 30 seconds. Then
re-insert the batteries at which point a double beep will be heard. This indicates that a successful pairing
has been achieved and the Doorbell button should be pressed within 30 seconds to confirm the
activation. If this process fails to pair the devices, please refer to the Trouble Shooting Guide and

User Hints section.

Please note the Doorbell has a built in anti-annoyance feature that restricts the activation of the device, please
read the Operation section for more details.
