How to use

Pair the transmitter and receiver by following the device pairing procedure: set the receiver into pairing mode, activate the transmitter to send its code, and confirm successful pairing by listening for a test chime. Select the preferred melody and adjust the volume level on the receiver. Test the system from several points within the premises to confirm reliable operation and adequate range.

Usage recommendations

For optimal performance place the receiver in an unobstructed outlet with clear line-of-sight to the main entrance or transmitter location. Keep the receiver away from large metal objects or other strong radio sources to minimise potential interference. If range is insufficient in sites with multiple walls or heavy construction, consider adding additional receivers paired to the same transmitter to ensure coverage.
