BEFORE STARTING
Before starting the installation, verify that you have the correct equipment and that
the equipment has not been damaged during transport.
1.2
SAFETY SUMMARY
Warning
This equipment contains dangerous mains voltages. Do not perform any
maintenance works with switched on mains supply.
Around the equipment
To minimise any possible shock hazard from an external power supply or lightning
strike, the chassis or equipment cabinet must be connected to an electrical ground.
Provide adequate ventilation around the rear of the equipment.
Do not operate in an explosive atmosphere
Do not operate the equipment in the presence of flammable gases or fumes.
Operation of any electrical equipment in such an environment constitutes a definite
safety hazard.
Do not attempt internal service while transmitting
Thermal or RF burns may result from touching certain components within the power
amplifier module while transmitting or operating the transmitter.
Do not substitute parts or modify the equipment
Because of the danger of introducing additional hazards, do not install substitute or
lower voltage parts to the equipment. Return to your authorised distributor.
Radio Frequency Exposure Warning
To meet the current requirements for Radio Frequency Exposure it is necessary to
install the antenna mast correctly and operate the equipment according to the
instructions.
The assumptions used in this assessment are: full transmit power is used, a good
antenna is used (assumed to be a unity gain (0 dB) wideband Omni-directional
type).
Where no suitable structure exists to achieve a 3 metre vertical separation then the
antenna base must be mounted at least 1 metre above the head of any person
within range and all persons must stay outside the 3-metre safety radius.
Failure to adhere to these limits could expose persons within the 3 metre radius to
RF radiation in excess of the MPE / SAR limits.
WARNING:
The antenna mast must be mounted at a minimum distance (vertical
separation) of 3 metres from the head of any person standing on deck to meet
international safety directives on Maximum Permissible Exposure (MPE) / Specific
Absorption Rate (SAR).
WARNING:
Do not transmit when persons are closer than 3 metres to the antenna.
If any person (e.g. the operator) must be closer, then a grounded RF shield should
be interposed between that person and the antenna.
