system can easily be expanded to include
high quality radio signals in every room.

If you have a long cable run from the aerial

Applications

SLx Boosters incorporate a Class 3 lter to
reduce 4G interference and are suitable
for digital TV signals Ch21-59 (470-782MHz)
however if you wish to receive TV on Ch60 you
should use an SLx Booster with IR Bypass. In
this case you may need a Ch60 lter if you
are affected by 4G interference (currently
available from at800 free of charge).

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
in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.

Line Powering
The SLx4 has built-in full line powering which
can be used to provide power to masthead
boosters. When connected to a masthead
amplier, the SLx4 will send the required power
out of the UHF socket up to the masthead
amplier (up to 25mA). Please see your
masthead amplier operating instructions for
more details.

In order to provide a non-interrupted 12V
power supply to the masthead amplier.
it is important to ensure that there is no
equipment between the UHF socket and the
masthead amplier output socket.
If equipment is connected in between,
the booster will not be able to detect the
masthead amplier and so will automatically
not output 12V.

General Safety Precautions

To Prevent Overheating

The recommended clearances and other precautions given in these instructions must be
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.

Other precautions

These appliances are not waterproof, they are intended for indoor use only and must not be
positioned where they could be exposed to dripping or splashing water. Objects containing
liquids should not be placed on or near the booster.
To prevent re, make sure the unit and attached cabling is installed well away from naked
ames and other heat sources.

Mains Plug

Your booster is supplied with a standard mains plug already tted, if you need to change
the plug use a competent professional (ELECSA or NICEIC) to make the connection.
If you need to change the fuse use a 3 Amp fuse to BS1362 carrying the ASTA or BSI
approved mark and ret the plastic fuse carrier.
