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 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!
Never transmit without an aerial attached to the transmitter
