Hi my name is Robert...
Below are the procedures for trying to get antenna to work...
The television (TV) antenna is a manual crank style antenna with BUILT in electronics that use 12 Volts DC to “boost” signal strength. A weak or fuzzy signal can be amplified by turning on the TV antenna power button on the video selector box. The antenna and booster work together to provide the best possible picture for most situations. Certain conditions may occur that require no amplification, and amplification may actually worsen the reception. In this case, the picture quality may improve by lowering the antenna and providing no amplification.
To Watch Main Television (Sharp) from the Antenna: On the video selector box press the television antenna POWER button ON. This provides +12 Volt power to the television antenna amplifier located inside the antenna housing. Press the TV ANT button located in the area marked MAIN TV. Turn on TV. Use Input button to select TV. For Home Theatre sound press Speaker switch to Home Theater. On DVD player press source button to select AUX 1 which will appear in window. Select desired channel on TV. Use volume control on DVD player to select desired sound level.
Hope this helps some.... Robert
