vi Ray54 VHF Radio
Antenna Mounting and EME Exposure
This system has a Maximum Permissible Exposure (MPE) Radius of 1.5
meters (per OET Bulletin 65), 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.
For watercraft with suitable structures, an omnidirectional antenna with gain
not greater than 3 dBi must be mounted a minimum of 3.5 meters vertically
above the main deck and all persons on board. For watercraft without suitable
structures, the antenna must be mounted so as to maintain a minimum of 1.5
meters vertically between the antenna (measured from the lowest point of the
antenna), to the heads of all persons.
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 FCC MPE limit. It is the radio operator’s
responsibility to ensure that no one comes within this radius.
For optimal radio performance and minimal human exposure to radio
frequency electromagnetic energy, make sure the antenna is:
• connected to the radio before transmitting
• properly mounted
• located where it will be away from people
• located at least 1.5 meters (5 feet) from the radio’s main unit
Safe Compass Distance
Safe Compass Distance is 1 meter for a common mechanical compass; other
compass types may require greater distances. 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.
