5. Maintenance

5.1. Transmitter Battery Replacement

The transmitter uses a CR2032 lithium battery, which boasts a maximum lifespan of 3 years under normal use. When the transmitter's LED no longer flashes or the signal becomes weak, it's time to replace the battery.

1. Locate the small notch on the side of the transmitter casing.
2. Carefully insert the provided key or a small flat-head screwdriver into the notch and gently pry open the casing.
3. Remove the old CR2032 battery.
4. Insert a new CR2032 battery with the positive (+) side facing up.
5. Align the two halves of the casing and press firmly until it clicks securely into place. Ensure the seal is tight to maintain its waterproof rating.

5.2. Cleaning

Wipe the doorbell units with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the surface or internal components. The transmitter is IP55 dustproof and waterproof, allowing it to withstand various harsh weather conditions, but avoid submerging it in water.

6. Troubleshooting

• No sound from receiver:
  • Ensure the receiver is properly plugged into a live electrical outlet.
  • Check if the receiver is in mute mode (0 dB volume). Adjust the volume using the volume button.
  • Verify that the transmitter battery is not depleted. Replace if necessary.
  • Re-pair the transmitter and receiver following the instructions in Section 4.3.
• Transmitter button does not light up:
  • The transmitter battery may be dead. Replace the CR2032 battery.
• Reduced wireless range or intermittent signal:
  • Ensure the distance between the transmitter and receiver is within the specified 1000 ft (300 m) range.
  • Relocate the receiver to a different outlet, preferably closer to the transmitter and away from large metal objects, thick walls, or other electronic devices that may cause interference.
  • Check the transmitter battery. A low battery can affect signal strength.
• Receiver LED flashes but no sound:
  • The receiver is likely in mute mode. Press the volume button to increase the sound level.
