NOTICE:
Do not remove the clear plastic shrink wrap from around the
video transmitter. Removal may result in damage to the components
attached to the board.
The supplied video transmitter is capable of transmitting on various
frequencies within the 5.8GHz band. Changing between frequencies is
accomplished by changing 3 of the 4 dip switches on the transmitter
board.
The 4th switch is not used, so its position is irrelevant.
Follow the table below to select the desired video frequency.
