JRC JMA-5212-4/6 User Manual page 10

Never directly touch the internal components of the
antenna, receiver/transceiver, or indicator. Direct
contact with these high-voltage components may cause
electrocution. For maintenance, inspection, or
adjustment of equipment components, consult with our
branch office, branch shop, sales office, or our distributor
in your district.
Do not get close to the radiant section of the antenna. It
is a rotating part, and it may cause injuries if it suddenly
starts rotating and consequently hits the body. It is
recommended that the radiant section be installed at a
high place such as on the roof of the wheelhouse, on the
flying bridge, on the trestle, or on the radar mast so that
no one can get close to it. When any work must be done
on the antenna, make sure to turn the antenna switch off.
Microwave radiation level of the antenna
Make sure to stay away from the microwave-radiating
antenna during transmission at least by the distances
indicated below. If the distance between you and the
front-center of the antenna is shorter than the distances
indicated below, exposure to microwave may result in
physical injuries (damage to the eye in particular).
NKE-2103 ( radio-density : 10 W/m
NKE-2254 ( radio-density : 10 W/m
Make sure to install the antenna at a place higher than
human height.
Direct exposure to electromagnetic waves at close range
will have adverse effects on the human body.
