Emergency Power Off
The antenna comes with an emergency power off feature. To activate it, press and hold
“POWER” and then press “SELECT” while still holding “POWER”. The antenna will stop
and turn off. If the emergency power off feature is used, the antenna may not be in a safe
position for travel. Do not move the vehicle until the unit is stowed.
HDTV Antenna/Satellite System
Your recreation vehicle may be equipped
with an exterior amplified high definition TV
antenna. The antenna comes equipped with
a signal meter and a power injector to aid in
receiving the strongest possible signal when
tuning in HDTV stations.
Antenna Positioning: The knob on the base
inside the RV is used to rotate the outdoor
roof antenna. The arrow on the knob should
be pointed towards the TV signal source (TV
station). Press the button on the side of the knob and turn it to rotate the antenna for opti-
mum signal. The antenna will rotate a full 360°.
Power Injector (if so equipped): The power injec-
tor button located on the wall plate, switches between
your cable/satellite signal and the over-the-air (OTA)
HDTV signals. When the button on the wall plate is
turned ON, it lights green and interrupts the satellite/
cable input to the TV. It allows the OTA HDTV sig-
nals from the outside roof antenna to your TV. When
the button is turned OFF, satellite/cable signals are re-
sumed again on your TV.
Signal Strength Meter (if so equipped): The base
may have a built in signal strength meter to aid in ob-
taining maximum TV signal. A row of LED lights will light up on the face of the base en-
closure to indicate signal strength. Optimum signal is indicated when the maximum number
of LEDs are lit.
• Make sure the power injector is turned ON at the wall plate which turns power on to
the antenna.
• To turn on the signal meter, slide the black button on the side of the base (arrow in
photo).
•
Rotate the small attenuator knob on the face of the base enclosure fully clockwise.
•
Press the button on the side of the large knob with the arrow, and rotate it until the
maximum number of LEDs light.
• Rotate the small attenuator knob counter-clockwise until the last illuminated LED light
flickers.
NOTE: This antenna is a fixed height (12”) and cannot be lowered or
raised. Trees and foliage will interfere with receiving a strong HDTV signal.
