PRX4SERL Four-Zone Receiver Decoder
To mount the unit on the wall, remove the two screws from the front of the case and separate the cover
from the base plate.
The base plate should be fixed to an even wall surface using suitable screws fitted through the 4.75 mm
holes provided in the chassis plate. Check that the chassis plate does not bend and that the screws do not
snag or pinch any internal cables.
Connect the antenna to the unit via the BNC connector located at the top of the housing. If the antenna is
an external type, care should be taken to ensure that certain installation criteria are met as detailed below.
Some major points to consider when installing equipment:
1.
Never install antennae near or adjacent to telephone, public address or data
communication lines or overhead power cables.
2.
Avoid, wherever possible, running antenna coax alongside other cables and avoid kinks
and coils. Pre-terminated cable should not be altered.
3.
Avoid mounting the receiver in the immediate vicinity of telephone exchanges or computer
equipment.
4. Always
use
50 ohm coaxial cable between the antenna and the receiver. If cable runs
exceed 5 meters, always use low loss 50 ohm cable such as RG213 or UR67 to a maximum
of 15 meters.
Coaxial cable intended for TV, Satellite or CCTV installations is normally 75 OHM
and therefore totally unsuitable for any receiver installation manufactured by
Scope.
5.
Also remember that the performance of the system will be affected by the type of material
the unit is mounted on and its surroundings.
The following is a list of materials that this receiver will be adversely affected by if
mounted on or if mounted in close proximity to:
a) Foil back plasterboard
b) Metal mesh or wire reinforced glass
c) Metal sheeting, large mirrors or suspended ceilings
d) Lift shafts
All of the above can reduce the ability of the receiver to perform its functions.
6.
The circuit boards within this equipment may be harmed by Electrostatic Discharge (ESD).
Installers should ensure that both themselves and the system’s chassis are grounded before
beginning any installation, and should ensure that adequate anti-static procedures are
adhered to at all times.
Warning:
Do not use the chassis plate as a template for drilling the holes into the wall. Hammer drills
may irreparably damage the quartz crystals on the printed circuit boards.
