SAFETY INSTRUCTIONS

WARNING
No one navigational aid should be relied
upon for the safety of vessel and crew.
The navigator has the responsibility to
check all aids available to confirm
position. Electronic aids are not
a substitute for basic navigational
principles and common sense.
This ARP automatically tracks
automatically or manually acquired radar
targets and calculates their courses and
speeds, indicating them by vectors. Since
the data generated by the auto plotter
are based on what radar targets are
selected, the radar must always be
optimally tuned for use with the auto
plotter, to ensure required targets will not
be lost or unwanted targets such as sea
returns and noise will not be acquired
and tracked.
A target does not always mean a land-
mass, reef, ships or other surface vessels
but can imply returns from sea surface
and clutter. As the level of clutter changes
with environment, the operator should
properly adjust the A/C SEA, A/C RAIN
and GAIN controls to be sure target
echoes are not eliminated from the
radar screen.
CAUTION
The plotting accuracy and response of
this ARP meets IMO standards.
Tracking accuracy is affected by the
following:
Tracking accuracy is affected by course
change. One to two minutes is required to
restore vectors to full accuracy after an
abrupt course change. (The actual
amount depends on gyrocompass
specifications.)
The amount of tracking delay is inversely
proportional to the relative speed of the
target. Delay is on the order of 15—30
seconds for high relative speed; 30—60
seconds for low relative speed.
The data generated by ARP, AIS and
video plotter are intended for
reference only.
Refer to official nautical charts for
detailed and up-to-date information.
