How to use

Install the battery in the receiver according to the polarity markings, then position the unit near the intended mounting location and secure it to the wall or surface.

After pairing, test the system by activating the transmitter and verifying that the receiver responds reliably. Replace the battery when signal strength or operation becomes intermittent.

Usage recommendations

For optimal reception, mount the receiver in a location with minimal large metal obstructions and avoid placing it inside metal cabinets. Keep the transmitter and receiver as line-of-sight as practical, and allow margin for walls and other obstacles which reduce range. Use quality alkaline batteries to ensure consistent operation and check contacts periodically for corrosion.
