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.
Electrical Shock
DANGER!! 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 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!
• 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.
Caution: Safety to
equipment
• 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.
• Changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.
• 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.
