- Select Ringtone: On the receiver, press the 'Up' or 'Down' control button (often labeled as Music Button) to cycle through the 58 available ringtones. Stop when you find your preferred melody.
- Enter Pairing Mode: Press and hold the 'Down' button and the 'Volume' button on the receiver simultaneously for 5-7 seconds. You will hear a 'ding' sound, and the blue LED light will flash, indicating the receiver is in pairing mode.
- Trigger Transmitter: While the receiver is in pairing mode, immediately press the push button (transmitter) you wish to pair. When you hear the selected ringtone from the receiver, it confirms that the pairing operation is completed successfully.
Repeat these steps for each additional transmitter you wish to pair, assigning a different ringtone if desired to distinguish between multiple entry points.

4.2 LED Strobe Indicator
In addition to audible chimes, the receivers feature an LED strobe light that flashes when the doorbell is activated. This visual alert is particularly beneficial for individuals with hearing impairments or in noisy environments.

6. Maintenance
To ensure the longevity and optimal performance of your PHYSEN Wireless Doorbell, consider the following maintenance tips:
- Cleaning: Wipe the surfaces of the transmitters and receivers with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
- Battery Replacement: The push button transmitters use an A23 battery. If the transmission range decreases or the button becomes unresponsive, it may be time to replace the battery. Refer to the transmitter's casing for instructions on opening and replacing the battery.
- Environmental Considerations: While the transmitters are waterproof, avoid submerging them in water. Ensure receivers are plugged into indoor outlets away from direct moisture.
