4.3 Mounting the Transmitter

Choose a flat, clean surface for mounting the transmitter. You have two options:

1. Using Adhesive Tape:
   • Clean the mounting area thoroughly to remove dust and grease.
   • Peel off one side of the double-sided adhesive tape and attach it to the back of the transmitter.
   • Peel off the other side of the tape and firmly press the transmitter onto the desired surface for at least 30 seconds.
2. Using Screws:
   • Open the transmitter casing to access the screw holes.
   • Mark the desired drilling points on the wall.
   • Drill holes and insert wall anchors if necessary.
   • Secure the transmitter base to the wall using the provided screws.
   • Reattach the transmitter casing.

For optimal performance, avoid mounting the transmitter on metal surfaces, which can reduce the wireless range.

1. Plug in the receiver.
2. Press and hold the 'Melody Selection' button on the receiver for approximately 5 seconds until the LED indicator flashes rapidly. This indicates pairing mode.

4. Repeat for each additional transmitter you wish to pair with this receiver.
5. To pair a transmitter with multiple receivers, repeat steps 2-3 for each receiver.

5.4 Silent Mode / LED Flash Only

To use the doorbell in silent mode with only the LED flash:

1. Press the 'Volume' button repeatedly until the volume reaches 0dB (mute).
