SAFETY INSTRUCTIONS
iv
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.
• The 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 ARP 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 and AIS are
intended for reference purposes only.
Check all available navigation aids to
determine target movement.
WARNING
To avoid electrical shock, do not
remove cover. No user-serviceable
parts inside.
WARNING LABELS
Warning labels are attached to the equipment.
Do not remove any label. If a label is missing or
damaged, contact a FURUNO agent or dealer
about replacement.
WARNING
Radiation hazard. Only qualified
personnel should work inside scanner.
Confirm that TX has stopped before
opening scanner.

TFT LCD
The high quality TFT (Thin Film Transistor) LCD
displays 99.999% of its picture elements.
The remaining 0.001% may drop out or light,
however this is an inherent property of the LCD;
it is not a sign of malfunction.
