For good station reception, the TV power supply must be turned
ON to view local television stations. Turning the TV power supply
ON sends 12-volt DC through the cable to the TV roof antenna.
The voltage energizes the transistors in the antenna head
amplifier. The TV signal then comes down the cable to the
outlets.
Turn the TV power supply OFF to view cable television or to
use a VCR or DVD.

To view local stations at either (or both) the front or bedroom television sets using
the television antenna, make sure the TV power supply is ON and the TV roof
antenna is raised to the operating position.
The following is an overview of the antenna operation. Refer to the manufacturer’s
user guide included in your Warranty Packet for detailed operating instructions, or
visit the manufacturer’s
website.
Raising the antenna
To raise the TV antenna to the operating position turn the antenna elevating crank
clockwise in the UP direction (approximately 13 turns) until some resistance to
turning is noted (Fig. 9.2).
On amplified models, 12-volt DC power is required. After the antenna is in the full
UP position, pull down on the round knob with both hands until it disengages from
the ceiling plate. Rotate the knob for best picture (Fig. 9.3).
To Test
1. Make sure the television set is working properly.
2. Switch the power supply ON and OFF to see if there is a difference in the
picture quality while watching TV. If there is no difference, refer to
manufacturer's manual for further testing procedures.
