observed to prevent overheating. In addition, units
should not be positioned where they are likely to
become covered by curtains, fabric or insulating
material. The amp should not be left resting on a
carpet or any other fabric surface.

Applications
SLx Boosters incorporate a Class 1 lter to
reduce 5G and 4G interference and are
suitable for digital TV signals Ch21-48
(470-694MHz) however if you wish to receive
TV on Ch60 you should use a DigiLink SLx
Booster with IR Bypass. Which may need a
5G/4G lter if you are affected by 5G or 4G
interference.
Installation
Important note: attention is drawn to the
General Safety Precautions Panel above
which contains advice on safe installation
and operation of these products.
Location
Choose a location for the booster from which
it is convenient to run cables from the
antennas and to the system outlets.Typical
examples of suitable locations are a loft
space or a cupboard. In weak signal areas it
is best to keep the aerial cables as short as
possible.
Select a cool, dry location to install the
booster.This means a location where the
ambient temperature will remain between
-10°C and +40°C, and which is free from risk of
dripping or splashing water.
The xing location should allow adequate
access to the equipment for wiring and
maintenance. Clearance of at least 25mm
should be allowed around the left hand
side and top of the unit for ventilation. More
clearance will be needed on the other sides
to allow access for cables.
Fixing
The booster should be xed to a wall or other
suitable hard surface using the keyhole slots
on the back of the housing and suitable
screws and wall plugs, a template is provided
on page 4.
The booster should not be left supported by
its own wiring, nor should it be left resting on a
carpet or other insulating and/or ammable
surfaces.
Signal Connections
Input and output signal connections are
made using IEC coax connectors. Good
quality plugs and digital quality double
screened coaxial cable should be used to
ensure optimum performance from your
booster.
Before Installing Please Note
1. Connect your TV aerial* downlead to the
“ANT IN” socket and connect the power
supply jack to the “DC12V” socket .
2. Connect your TVs/Freeview receivers/
satellite receivers to any of your booster”s
TV sockets (located on the top of the
booster) in any combination.
3. Plug the power supply into a mains wall
socket and switch on.
PLEASE NOTE: If your TV does not have a
built-in Freeview™ receiver you will need
to connect your TV to the booster via a
Freeview™ receiver or PVR.

Troubleshooting
If you experience reception problems after
installing your SLx booster, please see below:
No picture or sound
Is the signal reaching your TV? Check:
- Everything, including the booster is plugged
in and switched on
- Coaxial connections are correctly made
(no braid or foil is touching the inner core)
Picture or sound breaking up
- Use a UHF aerial suitable for your area,
ideally tted outdoors
- Use good quality coax cable, poorly
screened cable can pick up noise
- In some cases too much signal can cause
signal break-up, you can solve this by
tting an attenuator to the booster input
