The doorbell system is typically pre-paired. However, if you need to change ringtones or assign specific numbers to different transmitters, follow these steps:
Video: This video demonstrates how to change ringtones and set specific numbers for different transmitters on your SURFOU Wireless Doorbell system.
- Set the Ringtone for the Transmitter:
- Short press the "Backward" or "Forward" button on the receiver to select your desired ringtone. The receiver will play the selected tune.
- Long press the "Middle Volume" button on the receiver for about 8 seconds until it makes a "ding" sound and the LED number display lights up. This indicates it's in pairing mode.
- Set Numbers for Different Transmitters:
- While the receiver is in pairing mode (LED display lit), short press the "Backward" or "Forward" button to select the number (1-9) you wish to assign to the current transmitter.
- Within 8 seconds, press the transmitter button you want to pair. The receiver will emit two "ding" sounds, and the LED display will show the assigned number, confirming successful pairing.
- Note: This learning mode lasts only 8 seconds. If pairing is not completed within this time, the receiver will automatically exit pairing mode. Repeat the steps if necessary.
