Warnings and Cautions
Caution:
Use this radar at your own risk. This radar was designed for
use as a navigation aid. It should not be used for purposes that
require 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.
Caution:
If you purchased an open array radar antenna, make sure it is
installed in an area free of hardware obstructions and free of po-
tential obstructions like sails, lines or other vessel components
that could intermittently intrude or be caught up in the array
antenna's rotation path.
WARNING: High Voltage Hazard
Dangerously high voltages are present within the radar
scanner unit. The unit contains no user-serviceable
parts. The cover should be removed only by a qualified
radar service technician. Technicians must exercise ex-
treme care when working inside the unit. ALWAYS re-
move 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. There are no internal connections or adjust-
ments necessary for installation or operation.
