t
ravelling
Do not travel in the following
circumstances.
• With the antenna raised.
• With the antenna set for vertical signals.
When travelling adjust the antenna so that it
points to the rear of the vehicle to reduce the
possibility of damage when travelling.
o
perating
1. Firstly determine the approximate
location of the nearest transmitter and
whether the signals are horizontally
or vertically polarised. For assistance
ask your site operator or check other
antennas in the vicinity.
2. Loosen the mast locking collar and raise
the antenna. Rotate the mast to direct the
antenna towards the TV transmitter.
3. The H/V indicator on the bottom of the
mast indicates the back of the antenna.
4. Should you need to receive vertically
polarised signals, rotate the winder anti-
clockwise to tilt the antenna through 90º.
5. DO NOT use undue force on the winder.
6. Switch ON the amplifier and the LED will
illuminate.
7. Check the gain control is set to maximum.
For maximum rotate clockwise.
8. Tune your television into the strongest
signal. You may need to adjust the
direction of the mast to achieve the best
picture quality.
9. Secure by tightening the mast locking
collar.
DAB and FM Radio Operation
Status is designed to receive DAB and FM when
connected to a radio with DAB/FM facility.
Dependent on location, DAB and FM reception
may be improved by setting the antenna to
vertical.
Coaxial Connections
It is critical that all connections in the system
are fitted correctly.
Gain Control
In normal use the button should be rotated
clockwise for maximum. In strong signal areas
the amplification may need to be reduced. To
reduce amplification rotate the button anti-
clockwise until picture quality improves. The
button rotates through 270° from MAX to MIN.
LED Light
Should the LED on the amplifier not light,
firstly check there is power to the unit.
Secondly check the polarity is correct.
Otherwise contact Grade UK Ltd for further
assistance.
Short Hook Up: Test 1
This test isolates the wiring from the amplifier
through to your TV/radio points.
Unplug the coaxial plugs from the “TV” sockets
of the amplifier and use your TV fly lead with
converter 1 supplied. Connect your TV to the
amplifier.
