Detailed Answer
LIDER one-touch pairing: 1. Power on the receiver; 2. Press and hold the pairing button on the transmitter and the pairing button on the receiver simultaneously; 3. The buzzer/indicator confirms completion (1-3 seconds). After pairing, the old transmitter is automatically disabled. Re-pair after replacing a transmitter/receiver. Pairing requires no case opening — it is done on site in 1 minute.
