General Safety Warnings Concerning Use of 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
o
Before installing or replacing any of the equipment, the entire manual should be
read and understood.
o
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.
o
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
o
RF radiation, arising from transmitter outputs connected to AWL’s equipment,
must be considered a safety hazard.
o
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 50 ohm, and
that of free space at 377 ohm, 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!
o
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.
o
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.
Caution: Safety to
equipment
o
When installing, replacing or using this product, observe all safety precautions
during handling and operation. Failure to comply with the following general safety
precautions and with specific precautions described elsewhere in this manual
violates the safety standards of the design, manufacture, and intended use of this
product.
o
Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
o
Cobham Wireless assumes no liability for the customer's failure to comply with
these precautions. This entire manual should be read and understood before
operating or maintaining the repeater.
Warning: Restricted Access
Location
Access to the unit installation location is restricted to service personnel who have been
instructed on the restrictions and the required precautions to be taken.
