PRECAUTIONS
v
PRECAUTIONS
DANGER
Never carry out internal inspection or repair work of the equipment by users.
Inspection or repair work by unauthorized personnel may result in fire
hazard or electric shock.
For inspection and repair work of equipment components, consult with our
branch office, branch shop, sales office, or our distributor in your district.
When conducting maintenance, make sure to turn the main power off.
Failure to comply may result in electrocution.
Turn off the main power before cleaning the equipment. Especially
when a rectifier is used, make sure to turn it off since voltage is still output
from the rectifier even after the radar is turned off.
Failure to comply may result in equipment failure, electric shock or serious
injury.
When conducting maintenance work on the antenna, make sure to
turn its main power off.
Failure to comply may result in electrocution or injuries.

vi
PRECAUTIONS
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.
Microwave radiation level:
Keep away from a scanner when it is transmitting.
The high level of microwave is radiated from the front face of the
scanner specified below. The microwave exposure at close range
could result in injuries (especially of the eyes).

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.
Direct exposure to electromagnetic waves at close range will have adverse
effects on the human body. When it is necessary to get close to the antenna
for maintenance or inspection purposes, make sure to turn the indicator
power switch to "OFF" or "STBY."
When conducting maintenance work, make sure to turn off the power and
unplug the power connector J1 of the display unit so that the power supply
to the equipment is completely cut off.
Some equipment components can carry electrical current even after the
power switch is turned off, and conducting maintenance work without
unplugging the power connector may result in electrocution, equipment
failure, or accidents.
Do not take apart, and do not remodel the display unit. This could cause
water to seep inside the display unit.

PRECAUTIONS
vii
A malfunction may occur if the power in the ship is instantaneously
interrupted during operation of the radar. In this case, the power should be
turned on again.
Always use the automatic tuning mode.
Use the manual tuning mode only when the automatic tuning mode does
not provide the best tuning state due to deterioration of magnetron for
example.
If sensitivity is set too high, unnecessary signals such as noises in the
receiver and false echoes increase to lower target visibility.
At the same time, if sensitivity is set too low, detection of targets such as
ships and dangerous objects may be hindered.
Therefore, sensitivity must always be set to an optimal level.
When using the sea clutter suppression function, never set the suppression
level too high canceling out all image noises from the sea surface at close
range. Detection of not only echoes from waves but also targets such as
other ships or dangerous objects will become inhibited.
When using the sea clutter suppression function, make sure to choose the
most appropriate image noise suppression level.
Use the radar only as a navigation aid.
The final navigation decision must always be made by the operator
him/herself.
Making the final navigation decision based only on the radar display may
cause accidents such as collisions or running aground.
Use the target tracking function (TT) only as a navigation aid.
The final navigation decision must always be made by the operator
him/herself.
Making the final navigation decision based only on the target tracking
function (TT) information may cause accidents.
The target tracking function (TT) information such as vector, target
numerical data, and alarms may contain some errors. Also, targets that are
not detected by the radar cannot be acquired or tracked.
Making the final navigation decision based only on the radar display may
cause accidents such as collisions or running aground.
When a large value is set as an association condition, a tracked target near
an AIS target is identified as the AIS target and may thus disappear from the
display.
For example, when a pilot vessel equipped with the AIS function (a small
target which is not a tracked target) goes near a cargo vessel which is a
tracked target without the AIS function, the tracked target symbol for the
cargo vessel may disappear.

viii
PRECAUTIONS
Since these alarms may include some errors depending on the target
tracking conditions, the navigation officer himself should make the final
decision for ship operations such as collision avoidance.
Making the final navigation decision based only on the alarm may cause
accidents such as collisions.
When setting an automatic acquisition zone, make sure to properly adjust
gain, sea-surface reflection suppression level, and rain/snow reflection
suppression level so that the optimal target images are always on the radar
screen. The automatic acquisition zone alarm will not be activated for
targets undetected by the radar, and it may result in accidents such as
collisions.
Any adjustments must be made by specialized service personnel.
Incorrect settings may result in unstable operation.
Do not make any adjustments during navigation. Failure to comply may
result in adverse effects on the radar function which may lead to accidents
or equipment failure.
Any adjustments must be made by specialized service personnel.
Failure to comply may result in accidents or equipment failure.
Make sure to shut off the main power before replacing parts.
Failure to comply may result in electrocution or equipment failure.
When replacing magnetrons, make sure to shut off the main power and let
the equipment stand for more than 5 minutes to discharge the high-voltage
circuit.
Failure to comply may result in electrocution.
Make sure to take off your watch when your hand must get close to
the magnetron. Failure to comply may result in damage to the watch since
the magnetron is a strong magnet.
When cleaning the display screen, do not wipe it too strongly with a dry
cloth. Also, do not use gasoline or thinner to clean the screen.
Failure to comply will result in damage to the screen surface.
Do not take apart, and do not remodel the display unit. It may cause a fire,
the electric shock, and the breakdown.
