How to use
Mount the wireless transmitter at the entrance or desired activation point using the included fixing method or adhesive, ensuring it is within recommended range of the receiver. Plug the receiver into a suitable mains outlet indoors and select a melody from the available 32 chimes using the receiver controls. Enter learning mode on the receiver and activate the transmitter to complete pairing; repeat for additional transmitters as required. Test the system to confirm signal strength and adjust transmitter position if reception is weak.
Usage recommendations
Place the receiver away from large metal objects and other sources of radio interference to optimise range. For reliable indoor performance allow for signal attenuation through walls and floors; if needed, reposition the receiver to a more central location. Regularly check the transmitter battery status and use the learning pairing feature when adding or replacing transmitters to maintain correct operation.
