Symptoms
- No chime or alert when the trigger event happens
- Chime works only when very close to the base
- Random or false alerts happen
Likely causes
- CommonWeak batteries in the receiverLow battery power reduces both range and reliability.
- CommonDevices out of pairing syncA power loss on either the sender or receiver can break the pairing.
- PossibleDistance or obstructions between unitsWalls, especially with metal or brick, cut wireless range significantly.
- PossibleInterference from other wireless devicesOther devices using the same frequency can cause missed signals.
- Less commonVolume or mute setting on the receiverAn accidentally muted or low volume setting can seem like a failure.
What to do
- Replace batteries in both the sender and receiver units.
- Check the volume isn't muted or turned down on the receiver.
- Re-pair the units following the manufacturer's sync procedure.
- Move the receiver closer to the sender to test range.
- Reduce obstructions between the two units where possible.
- Move other wireless devices away from the base unit temporarily.
- Replace the unit if pairing and fresh batteries don't restore reliable operation.
