| If | Then |
|---|---|
| The doorbell does not work | 1. Press the Mute button until all of the Mute lights are off. |
| 2. Make sure that correct batteries (4 C alkaline cells, 1 CR2032) are installed with the correct polarity. | |
| 3. The doorbell might be out of range; try the doorbell in a different location. | |
| 4. Re-connect the doorbell. See "Connect a Push Button" on page 8. | |
| 5. Check all the batteries and replace if needed. | |
| 6. Check if the confidence LED on the transmitters is working when activated. | |
| 7. Check if the doorbell is muted. | |
| 8. Check that the transmitter is linked with the chime.* | |
| Two 'beep' sounds are heard after the normal tune | 1. Replace doorbell push battery with a new CR2032. |
| The halo light flashes yellow at the bottom edge | Replace doorbell batteries with 4 new C alkaline batteries. |
| Range is reduced | 1. Metal structures including uPVC door frames can reduce the range. Don't mount the the doorbell or doorbell push on or near metal structures. 2. Move the doorbell closer to the doorbell push button. 3. Weak batteries will reduce range. In cold conditions (below 5°C), batteries may need to be replaced more often. |
