Radio Operation Warning - Icom IC-M510BB Instruction Manual

■ Radio Operation Warning

Icom requires the radio operator to meet the FCC Requirements for Radio
Frequency Exposure. An omnidirectional antenna with gain not greater than
9 dBi must be mounted a minimum of 5 meters (measured from the lowest
point of the antenna) vertically above the main deck and all possible
personnel. This is the minimum safe separation distance estimated to meet
W ARN ING
all RF exposure compliance requirements. This 5 meter distance is based
on the FCC Safe Maximum Permissible Exposure (MPE) distance of 3 meters added to
the height of an adult (2 meters) and is appropriate for all vessels.
For watercraft without suitable structures, the antenna must be mounted so as to maintain
a minimum of 1 meter vertically between the antenna, (measured from the lowest point
of the antenna), to the heads of all persons AND all persons must stay outside of the 3
meter MPE radius.
Do not transmit with radio and antenna when persons are within the MPE radius of
the antenna, unless such persons (such as driver or radio operator) are shielded from
antenna field by a grounded metallic barrier. The MPE Radius is the minimum distance
from the antenna axis that person should maintain in order to avoid RF exposure higher
than the allowable MPE level set by FCC.
FAILURE TO OBSERVE THESE LIMITS MAY ALLOW THOSE WITHIN THE MPE
RADIUS TO EXPERIENCE RF RADIATION ABSORPTION WHICH EXCEEDS THE
FCC MAXIMUM PERMISSIBLE EXPOSURE (MPE) LIMIT.
IT IS THE RESPONSIBILITY OF THE RADIO OPERATOR TO ENSURE THAT THE
MAXIMUM PERMISSIBLE EXPOSURE LIMITS ARE OBSERVED AT ALL TIMES
DURING RADIO TRANSMISSION. THE RADIO OPERATOR IS TO ENSURE THAT
NO BYSTANDERS COME WITHIN THE RADIUS OF THE MAXIMUM PERMISSIBLE
EXPOSURE LIMITS.
Determining MPE Radius
THE MAXIMUM PERMISSIBLE EXPOSURE (MPE) RADIUS HAS BEEN ESTIMATED
TO BE A RADIUS OF ABOUT 3 M PER OET BULLETIN 65 OF THE FCC.
THIS ESTIMATE IS MADE ASSUMING THE MAXIMUM POWER OF THE RADIO AND
ANTENNAS WITH A MAXIMUM GAIN OF 9 dBi ARE USED FOR A SHIP MOUNTED
SYSTEM.
