reduce 4G interference and are suitable
for digital TV signals Ch 21-59 (470-782MHz)

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 aerial
and to the rooms with TV’s. Typical examples
of suitable locations are a loft space or a
cupboard. In weak signal areas it is best to keep
the cable from the aerial as short as possible.

Select a cool, dry location to install the
amplier. 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.

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 are 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.
