Precautions Upon Equipment Operation
Do not disassemble or modify the equipment. Failure
to observe the instruction can cause a fire, electric
shock, or equipment failure.
Do not connect or disconnect the power supply cable
with a wet hand. Otherwise, you may suffer from an
electric shock.
Operate the equipment only at the power supply
voltage of 12 or 24 VDC. Failure to observe this
instruction can cause a fire, electric shock, or
equipment failure.
Do not scratch, damage, or modify the power supply
and antenna cable. It may be damaged to cause a fire
or electric shock if it is loaded with a heavy item, heated,
pulled, or excessively bent.
Do not operate the equipment while steering the
vessel. It can cause accidents.
Immediately turn the power off and disconnect the
power supply cable if the equipment is generating any
smoke or odor, or found overheated. Then, promptly
inform our local service agent of the symptom to have
it corrected. Prolonged equipment operation under
such a condition can cause a fire or electric shock.

No
This equipment is not designed to automatically make
judgments on the position data. The navigation
information including the position data needs to be
judged by the user himself.
Do not allow the equipment to fall or immerse in water.
The equipment can be damaged.
When removing the power and antenna cord, be sure
to remove the cord terminal correctly. If the cord is
pulled, the cord may be damaged resulting in a fire or
an electrical shock.
When cleaning the surface, do not use any or-
ganic solvent such as thinner or benzine.
Otherwise, the painting on the surface may be
damaged.
For cleaning the surface, remove the dust and
refuse and wipe with clean dry cloth.

Key Terms
TermDescription
GPS satellites The term is an acronym that represents the Global Positioning System,
which is managed by the US Department of Defense to support its
navigation aid system.
DGPS The term is an acronym that represents the Differential Global
Positioning System, which is a system to improve the position fixing
accuracy by receiving the correction data with a beacon receiver for a
given GPS satellite, which is transmitted by the beacon station with a
known position.
Position fixing The term means to obtain the current position of your vessel with the
GPS or DGPS receiver.
2D (Two-dimensional position fixing) The term 2D means the position fixing with data obtained from the satel-
lites and antenna height information.
3D (Three-dimensional position fixing)
The term 3D means the position fixing with four or more satellites infor-
mation only.
HDOP The term is an acronym that represents the Horizontal Dilution of
Precision, which reflects the position fixing accuracy. The accuracy
increases as the value decreases.
The value increases when the satellites are gathered close to each other,
and it reduces when the satellites are spattered, which in turn means
increased accuracy.
Loran time difference display This is a method to display the current position using the time difference.
(This method is recommended for the experts who have good knowl-
edge on the Loran navigation method.)
TD The term is an acronym that represents the Time Difference, which is
equal to the time difference between the master and secondary Loran
signals.
Route plan This is the plan that consists of the multiple waypoints registered in the
order of navigation.
CDI The term is an acronym that represents the Course Deviation Indicator,
which includes information on the deviation from a given planned course
and direction to be steered.
