Some major points to consider when installing equipment:
1
Never install antennas near or adjacent to telephone, public address or data
communication lines or overhead power cables.
2
Avoid, where ever possible, running antenna coax alongside other cables.
3
Avoid mounting the transmitter in the immediate vicinity of telephone exchanges
or computer equipment.
4
Always use proprietary 50 ohm coaxial cable between the antenna and the
transmitter. If cable runs exceed 5 metres, always use low loss 50 ohm cable
such as RG213, UR67 or equivalent.
Coaxial cable intended for TV, Satellite or CCTV installations is normally 75 OHM
and therefore totally unsuitable for any transmitter installation manufactured by
Scope.
5
Also remember that the performance of the system will be effected by the type of
material the unit is mounted on and its surroundings.
The following is a list of materials that this transmitter 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 reflect radio waves and thereby reduce the capability of the
transmitter to perform its desired functions.
6
The circuit boards within this equipment may be harmed by Electrostatic
Discharge (ESD). Installers should avoid touching the circuitry wherever possible,
and should ensure that adequate anti-static procedures are adhered to at all times
(earth bonding with wrist straps, etc).
7
Warning!
Never transmit without an aerial attached to the transmitter
8
Warning!
Carefully check the
Installation
section in this manual covering data
pin connections prior to installation. Damage caused by incorrect connection is
the responsibility of the installer!
