General Safety Warnings Concerning Use of This System
Always observe standard safety precautions during installation, operation and maintenance
of this product. Only a qualified and authorized personnel should carry out adjustment,
maintenance or repairs to the components of this equipment.
NOTE: Please refer to Axell Wireless for additional information and for requests for
notifications to authorities.
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
This equipment can either be installed indoors or outdoors. When
installed outdoors - wet conditions increase the potential for receiving an
electric shock when installing or using electrically powered equipment. 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: RF Exposure
RF radiation, (especially at UHF frequencies) 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!
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.
For FCC compliance, the Maximum Channel output must be <5 watts.
Warning: Antenna
Installation
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.
Installation of an antenna must comply with the FCC RF exposure
requirements.
The antenna used for this transmitter must be mounted on outdoor or
indoor permanent structures. The maximum antenna gain for indoor
operation is 2.2 dBi. In indoor applications the antenna must be installed
at a minimum separation distance of 58 cm from all nearby persons.
