  • Select volume: Press button 3 on the doorbell.

Button Location and Installation

Before permanent installation, test the range and reliability of the device in your chosen location. Avoid placing the button directly on metal objects or materials containing metal (e.g., steel posts, metal-framed doors), as this may interfere with the signal.

Installation steps
Installation steps
  1. Pair the button with the doorbell first.
  2. Attach the installation pad to the surface using double-sided tape or screws (use dowels if screwing in).
  3. Place the button onto the attached rear part.

Troubleshooting

If the receiver does not ring after pressing the transmitter button, check the following:

  • Ensure the distance between the transmitter and receiver is not too great.
  • Check for strong sources of signal interference, such as radio/wireless networks, large metal objects, or reinforced concrete walls.

Replacing Batteries

Transmitter: Open the cover with a flathead screwdriver, insert the CR2032 battery as indicated on the plate, and reattach the cover.

Replacing transmitter battery
Replacing transmitter battery

Receiver: Open the back cover, insert 2x AA batteries, and close the cover.

Note: The doorbell has internal memory to store paired transmitter codes in case of power failure. The selected melody is retained, but the volume must be set again after a power outage.
