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 suspended ceiling voids, or in the immediate vicinity of
telephone exchanges or computer equipment.
4
Always use 50 ohm coaxial cable between the antenna and the transmitter. If cable runs
exceed 5 meters, always use low loss 50 ohm cable such as RG213 or UR67.
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 affected 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 wallboard
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.
7
Warning! Never transmit without an aerial attached to the transmitter
8
Warning! Carefully check the Installation section in this manual covering terminal
connections prior to installation. Damage caused by incorrect connection is the responsibility
of the installer!
