easily damage coaxial cable and should be
avoided. Coaxial cable, if placed in close
proximity to electrical cables, transformers
or other pieces of electrical equipment,
may pick up electrical interference causing
picture quality to deteriorate, especially in
poor reception areas. Excess cable should
be removed and NOT coiled as this may
cause picture distortion. An inspection
of the routing of the cable is highly
recommended to ensure all is correct.
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
degrees 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 using you
TV fly lead with Converter 1 supplied.
Connect your TV to the Amplifier.
Please ensure the antenna dome is
plugged directly into the ‘ANT-IN’ socket
of the amplifier and switch on. Tune in
your TV for the strongest signal.
If the picture quality improves the fault lies
with the wiring of the system between the
Amplifier and the TV outlet socket.
Short Hook Up – Test 2
This test isolates the amplifier by
connecting your TV direct to the antenna.
Unplug the antenna from the amplifier and
connect Convertor 2 supplied to the plug
on the cable end. Using your TV Fly Lead
connect the antenna directly to your TV.
Tune in your TV for the strongest signal.
If the picture quality improves, the fault lies
with the Vision Plus Amplifier.
Antenna Dome Coaxial Cable
Check the routing of the coaxial cable from
the antenna dome to the amplifier. Check
to ensure there are no kinks or trapped
cable or if there are loops of surplus cable
which could be aecting performance.
Radio reception troubleshooting.
If you experience any loss or poor radio
reception signals, when please try the
following steps.
• Are all connectors on the
amplifier connected?
• Are there any obvious obstructions in
the vicinity that may impair reception?
• What position is the antenna head in?
For radio reception it is advised that
head be in the vertical position for
better coverage.
• Has someone else got a better reception?
Coverage varies geographically.
