1.2 Power-on Initial Configuration
1) Power-on: Connect DC12V power supply adapter with power supply socket
2) Initial Configuration: The remote control receiving indicator flashes after it power on, the pan-tilt turns
left to the lowest point, and then turns to the HOME position (both the horizontal and vertical positions are
in the middle), while the movement first shrinks and then stretches. When remote control receiving
indicator stops flashing, the self-checking is complete.
Notes:
1) After power on and self-checking, the camera will automatically return to the preset 0 position if it’s
pre-set.
2) The default address for the IR remote control is 1#. If the camera is restored to factory defaults, the
remote-control default address will restore to 1#.
