Pairing and clearing method:
The game camera must be in switch-on mode to be paired with the
receiver. A receiver can only be paired with 6 game cameras (art. no.

replaced and the cycle is repeated.
Pairing: After switching on the receiver, all 6 indicators flash if the
camera / receiver is not paired. Press and hold the volume button (5)
for 3 seconds to activate the pairing mode: When an LED indicator
lights up and flashes, then use a paper clip to pair the game camera
