Warnings and Cautions
Caution:
Use the radar at your own risk. Your radar was designed for use
as a navigation aid. It should
not
be used for purposes that re-
quire precise measurements of direction, distance, topography or
location. Always compare the navigation information received
from your radar with data from other navigation aids and
sources. When a conflict arises between the navigation data from
your radar and data from other navigation aids, make sure you
resolve the conflict before proceeding with navigation.
A CARE-
FUL NAVIGATOR NEVER RELIES ON ONLY ONE
METHOD TO OBTAIN NAVIGATION INFORMATION.
Caution:
International Regulations for Preventing Collisions at Sea man-
date that when radar is on a vessel, the radar must be used at
all times, regardless of weather conditions or visibility. Numer-
ous court decisions have not only ruled the radar must be used,
but that the radar operator must be knowledgeable in all opera-
tional aspects of radar performance or otherwise face a greater
risk of liability if an accident occurs.
WARNING:
High Voltage Hazard
Dangerously high voltages are present within the radar
scanner unit. Technicians must exercise extreme care
when working inside the unit. ALWAYS remove power
before removing the cover. Some capacitors may take
several minutes to discharge, even after switching off
the radar. Before touching the magnetron or any high
voltage components, ground them with a clip lead.
WARNING:
Microwave Radiation Hazard
The microwave energy radiated by a radar antenna is
harmful to humans, especially to the eyes. NEVER look
directly into an open waveguide or into the path of ra-
diation from an enclosed antenna. Radar and other ra-
dio frequency radiation can upset cardiac pacemakers.
If someone with a cardiac pacemaker suspects abnormal
operation, immediately turn off the radar equipment
and move the person away from the antenna. Turn off
the radar whenever it is necessary to work on the an-
tenna unit or other equipment in the beam of the radar.
