PRODUCT DESCRIPTION AND USER’S MANUAL
General Safety Warnings Concerning Use of This System
Always observe standard safety precautions during installation, operation and maintenance of this
product.
Caution labels!
Throughout this manual, there are "Caution" warnings. "Caution" calls
attention to a procedure or practice, which, if ignored, may result in
injury or damage to the system, system component or even the user.
Do not perform any procedure preceded by a "Caution" until the
described conditions are fully understood and met.
Danger: Electrical
Shock
To prevent electrical shock when installing or modifying the system
power wiring, disconnect the wiring at the power source before
working with un insulated wires or terminals.
Caution: Safety to
personnel
Before installing or replacing any of the equipment, the entire manual
should be read and understood.
The user needs to supply the appropriate AC or DC power to the
repeater. Incorrect power settings can damage the repeater and may
cause injury to the user.
Please be aware that the equipment may, during certain conditions
become very warm and can cause minor injuries if handled without any
protection, such as gloves.
Caution: RF Exposure
RF radiation, arising from transmitter outputs connected to AWL’s
equipment, must be considered a safety hazard.
This condition might only occur in the event of cable disconnection, or
because a ‘spare’ output has been left un-terminated. Either of these
conditions would impair the system’s efficiency. No investigation
should be carried out until all RF power sources have been removed.
This would always be a wise precaution, despite the severe mismatch
between the impedance of an N type connector at 50Ω, and that of free
space at 377Ω, which would severely compromise the efficient
radiation of RF power. Radio frequency burns could also be a hazard,
if any RF power carrying components were to be carelessly touched!
Antenna positions should be chosen to comply with requirements (both
local & statutory) regarding exposure of personnel to RF radiation.
When connected to an antenna, the unit is capable of producing RF
field strengths, which may exceed guideline safe values especially if
used with antennas having appreciable gain. In this regard the use of
directional antennas with backscreens and a strict site rule that
personnel must remain behind the screen while the RF power is on, is
strongly recommended.
Where the equipment is used near power lines or in association with
temporary masts not having lightning protection, the use of a safety
earth connected to the case-earthing bolt is strongly advised.
