To sync your PetSpy M686 Premium Dog Training Shock Collar remote with the receiver collar, follow these steps: First, ensure both the remote transmitter and the receiver collar are fully charged and switched on. Next, activate synchronization mode on the collar by pressing and holding the power button for approximately 5 seconds. The red on the collar will begin to flash rapidly, indicating it's ready to pair. Within this flashing period, activate a command from the remote; we suggest trying the vibration function. Press and hold the vibration button on the remote until you feel the collar vibrate. This action establishes the connection. If no command is sent within 10 seconds, the flashing on the collar will cease. Finally, your devices are now synchronized! Test the connection by sending any command from the remote to the collar. If you have a two-collar system, repeat these steps for each collar, using channel 1 and channel 2 as needed. For more detailed visual instructions, please consult the PetSpy M686 Premium Dog Training Shock Collar user manual, available for download on the PetSpy website at www.petspystore.com.
