Ray49 Marine VHF Radio
Antenna Mounting and EME Exposure
For optimal radio performance and minimal human exposure to radio frequency
electromagnetic energy, make sure the antenna is:
• located at least 1.5 meters (5 feet) from the radio
• connected to the radio before transmitting
This system has a Maximum Permissible Exposure (MPE) Radius of 1.5 meters,
assuming the maximum power of the radio and antennas with a maximum gain
of 3dBi. Accounting for the height of an average adult (2 meters) the minimum
height of the antenna above the deck to meet RF exposure compliance
requirements is 3.5 meters. Antennas with more gain require a greater MPE
radius. Do not transmit when anyone is within the MPE radius of the antenna,
unless shielded from the antenna field by a grounded metallic barrier.
WARNING: Maximum Permissible Exposure
Failure to observe these guidelines may expose those within the
maximum permissible exposure (MPE) radius to RF radiation
absorption that exceeds the MPE limit. It is the operator’s
responsibility to ensure that no one comes within this radius.
WARNING: Microwave Radiation
Operators with cardiac pacemakers, electric-medical equipment
and life support machines should not be exposed to microwave
radiation.
CAUTION: Antenna Connection
Never operate the radio unless it is connected to the antenna.
Safe Compass Distance
Safe Compass Distance is 1 meter for a common compass. To be sure, you should
locate the radio as far as possible from the compass. Test your compass to verify
proper operation while the radio is also operating.
EMC Conformance
All Raymarine equipment and accessories are designed to the best industry
standards for use in the recreational marine environment. Their design and
manufacture conform to the appropriate Electromagnetic Compatibility (EMC)
standards but correct installation and use is required to ensure that performance
is not compromised.
Duty Cycle
The normal duty cycle of the Ray 49 is 5% transmit, 5% receive, and 90% standby.
