Method A: Using Double-Sided Adhesive Tape

1. Clean the desired mounting surface thoroughly to ensure it is free of dust and moisture.
2. Peel off one side of the protective film from the double-sided adhesive tape and attach it to the back of the transmitter.
3. Peel off the other side of the protective film and firmly press the transmitter onto the cleaned surface for at least 30 seconds.

Method B: Using Screws and Anchor Plugs

1. Mark the desired mounting points for the transmitter on the wall.
2. Drill two holes at the marked positions.
3. Insert the anchor plugs into the drilled holes.
4. Align the transmitter's mounting holes with the anchor plugs and secure it with the provided screws.

Important: To prevent signal interference, do not install the transmitter close to or on metal surfaces such as metal door frames or mailboxes.

5.2 Plugging in the Receiver

Plug the receiver into a standard electrical outlet in a location where the chime can be easily heard. The LED on the receiver will flash upon initial power-up.

5.3 Pairing the Doorbell System

The transmitter and receiver are pre-paired at the factory. If re-pairing is needed or if you add additional transmitters/receivers, follow these steps:

1. Plug the receiver into a power socket.
2. To enter pairing mode, hold down the Volume button on the receiver for 3 seconds. The LED on the receiver will flash.
3. Remove the battery insulating film from the transmitter (if not already done).
4. Press the Push button on the transmitter. Its LED will flash.
5. After successful pairing, the receiver will chime once, and the LEDs on both the receiver and transmitter will flash simultaneously.

7. Maintenance

7.1 Cleaning

Wipe the devices with a soft, dry cloth. Do not use abrasive cleaners or solvents.

7.2 Battery Replacement (Transmitter)

The transmitter uses a CR2 battery with an estimated lifespan of 3 years. When the battery is low, the transmitter's LED may not light up or the signal range may decrease. To replace the battery:

1. Carefully open the transmitter casing using the provided screwdriver or a small flat-head screwdriver.
2. Remove the old CR2 battery.
3. Insert a new CR2 battery, ensuring correct polarity (+/-).
4. Close the casing securely.

8. Troubleshooting

• Doorbell not chiming: Ensure the receiver is plugged in and powered. Check the transmitter battery. Re-pair the devices if necessary (refer to Section 5.3).
• Short signal range: Ensure the transmitter is not installed on or near metal surfaces. Relocate the receiver to a more central position. Replace the transmitter battery.
• Interference: The doorbell operates on a frequency that minimizes interference with other household devices. If interference occurs, try changing the melody or relocating the receiver.
• Memory Function: The device remembers your last melody and volume level after a power outage, so no need to reset settings.
