How to discard this product
Discard this product according to local regulations for the disposal of industrial waste. For disposal in
the USA, see the homepage of the Electronics Industries Alliance (http://www.eiae.org/) for the
correct method of disposal.
How to discard a used battery
Some FURUNO products have a battery(ies). To see if your product has a battery, see the chap-
ter on Maintenance. Follow the instructions below if a battery is used. Tape the + and - terminals
of battery before disposal to prevent fire, heat generation caused by short circuit.
In the European Union
The crossed-out trash can symbol indicates that all types of batteries
must not be discarded in standard trash, or at a trash site. Take the
used batteries to a battery collection site according to your national leg-
islation and the Batteries Directive 2006/66/EU.
In the USA
The Mobius loop symbol (three chasing arrows) indicates that
Ni-Cd and lead-acid rechargeable batteries must be recycled.
Take the used batteries to a battery collection site according to
local laws.
In the other countries
There are no international standards for the battery recycle symbol. The number of symbols can
increase when the other countries make their own recycle symbols in the future.

SAFETY INSTRUCTIONS
WARNING
Indicates a condition that can cause death or serious
injury if not avoided.
CAUTION
Indicates a condition that can cause minor or moderate
injury if not avoided.
Warning, Caution Mandatory Action
Prohibitive Action
Read these safety instructions before you operate or install the equipment.
WARNING
Radio Frequency Radiation Hazard
The radar antenna sends the electromagnetic
radio frequency (RF) energy. This energy can
be dangerous to you, especially your eyes.
Do not look at the radiator or near the
antenna when the antenna is rotating.
The distances at which RF radiation levels of
100 W/m2, 50 W/m2and 10 W/m2exist are
shown in the table.
Note: If the antenna unit is installed at a
close distance in front of the wheel house,
prevent the transmission in that area to
protect passengers and crew from microwave
radiation. Set the [Sector Blanks] in the
[System] menu.
Distance to
100 W/m2point
Distance to
50 W/m2point
Distance to
10 W/m2point
Worst case 1.1 m
Standard Steering
Display unit 0.45 m 0.30 m
CAUTIONCAUTION
M1815 Antenna unit 1.70 m 1.05 m
Unit
Observe the following compass safe distances to
prevent deviation of a magnetic compass.
WARNING
Do not open the equipment.
The equipment uses high voltage that
can cause electrical shock. Refer any
repair work to a qualified technician.
Before turning on the radar, be sure
no one is near the antenna.
Prevent the potential risk of being
struck by the rotating antenna, which
can result in serious injury or death.
If water leaks into the equipment or
something is dropped into the
equipment, immediately turn off the
power at the switchboard.
Fire or electrical shock can result.
If the equipment is giving off smoke
or fire, immediately turn off the
power at the switchboard.
Fire or electrical shock can result.
Do not disassemble or modify the
equipment.
Fire, electrical shock or serious injury
can result.
Do not place operate the equipment
with wet hands.
Electrical shock can result.

SAFETY INSTRUCTIONS
iii
WARNING
Usethe correct fuse.
Use of a wrong fuse can result in fire or
damage to the equipment.
Do not place liquid-filled containers
on the equipment.
Fire or electrical shock can result if a
liquid spills into the equipment.
CAUTIONCAUTION
The guard zone alarm is an effective aid
to anti-collison.
Its use does not relieve the operator of the
responsibility to keep a vigilant watch on
his or her surroundings.
The data presented by this equipment
is intended as a source of navigation
information.
The prudent navigator never relies
exclusively on any one source of
navigation information, for safety of
vessel and crew.
WARNING
The TT function is a valuable aid to
navigation. However, the navigator
must check all aids available to avoid
collision.
- The TT automatically tracks an
automatically or manually acquired
radar target and calculates its course
and speed, indicating them with a
vector. Since the data generated by
the TT depends on the selected radar
targets, the radar must be optimally
tuned for use with the TT, to ensure
required targets will not be lost or
unnecessary targets, like sea returns
and noise, will not be acquired and
tracked.
- A target is not always a landmass,
reef, ship, but can also be returns
from the sea surface and from clutter.
As the level of clutter changes with
the environment, the operator must
correctly adjust the sea and rain
clutter controls and the gain control so
that the target echoes do not dis-
appear from the radar screen.
TT safety information
CAUTIOCAUTION
The plotting accuracy and response of
this TT 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 approx. 15-30 seconds for
the higher relative speed; approx. 30-60
seconds for the lower relative speed. The
following factors can affect accuracy:
- Echo intensity
- Radar transmission pulse length
- Radar bearing error
- Gyrocompass error
- Course change (own ship and targets)

SAFETY INSTRUCTIONS

WARNING
To avoid electrical shock, do not
remove cover. No user-serviceable
parts inside.
WARNING
Radiation hazard. Only qualified
personnel should work inside scanner.
Confirm that TX has stopped before
opening scanner.

FURUNO agent or dealer about replacement.
TFT display
The high quality TFT (Thin Film Transistor) LCD
displays 99.99% of its picture elements. The
remaining 0.01% may drop out or light,. However,
this is an inherent property of the TFT; it is not a
sign of malfunction.
