Basic Camera Setup
Turn on your TV.
Turn on your TV and select its video input. Use the Video or Select
buttons on your TV remote control, or try channel 0 and then
Channel Down. The camera's picture should appear. Note, the
picture will be upside down because the camera is intended to be
mounted on a ceiling or overhang, after installing it into the dome.
See page 22 if you want to flip the picture.

Fine tune the antennas.
Once the camera and receiver are in place, adjust their antennas so
that they face each other. The side of the camera's antenna with the
dot on it should face the side of the receiver's antenna marked with
four squares. Adjust the positions to improve the picture on your TV.
