5. Safety Information & Pre-installation Notes

To ensure optimal performance and safety, please observe the following:

• Wireless signals are susceptible to interference from metal, thick walls, and concrete structures. Similar to how a mobile phone might lose signal in an elevator or an enclosed iron room, these materials can weaken or block the doorbell's signal.
• For best results, install the transmitter and receiver in an open, interference-free environment. The maximum range of 300 meters is achievable under ideal conditions.
• Avoid installing the transmitter button on metal doors or door frames, as metal can significantly interfere with the signal and shorten the effective range. If the reception distance is particularly short, try relocating the receiver.
• Keep the receiver away from potential sources of electromagnetic interference such as induction cookers, televisions, speakers, and other devices that generate strong magnetic fields or signals.
• The signal strength is generally better when the transmitter and receiver are in a direct line of sight, and the signal effect is better when passing through fewer walls.
