WARNING WARNINGWARNING
Before servicing the radar, turn
off the appropriate external
breaker.
ELECTRICAL SHOCK HAZARD.
Do not open the equipment.
Turn off the radar power switch
before servicing the antenna
unit. Post a warning sign near
the switch indicating it should
not be turned on while the
antenna unit is being serviced.
Only qualified personnel should
work inside the equipment.
Use the proper fuse.
Use of a wrong fuse can result
in damage to the equipment or
cause fire.
Prevent the potential risk of being
struck by the rotating antenna
and exposure to RF radiation
hazard.
Do not place liquid-filled con-
tainers near the equipment.
Fire or electrical shock can result
if a liquid spills into the equipment.
Do not operate the equipment
with wet hands.
Electrical shock can result.
Keep heater away from equipment.
Heat can alter equipment shape
and melt the power cord, which
can cause fire or electical shock.
Do not disassemble or modify
the equipment.
Fire, electrical shock or serious
injury can result.
Immediately turn off the power
at the ship’s mains switchboard
if water leaks into the equip-
ment or the equipment is emit-
ting smoke or fire.
Continued use can cause fatal
damage to the equipment.
This equipment has a valid
latitude range of 85°N to 85°S.
Operation outside of this range
can result in a larger margin of
error when calculating position,
heading, bearing, etc.
Power is not removed from the
radar simply by turning off its
power switch.

WARNING
CAUTION
CAUTION
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 TT 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.
The plotting accuracy and response of
this TT meets IMO standards. Tracking
accuracy is affected by the following:
The data generated by TT, AIS and
video plotter are intended for
reference only.
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 target tracking and pertinent vector
calculation accuracy is influenced by the
following:
- Echo intensity
- The range measurement accuracy;
characterized by both random and biased
measurement errors.
- The angular measurement accuracy;
characterized by beam shape, target glint
and bias errors.
- Radar transmission pulsewidth
- Gyrocompass heading error
- Speed log error
- Curent and wind (set & drift)
- Course change (own ship and target)
Refer to official nautical charts for detailed and
up-to-date information.
DANGER
Electrical shock hazard.
Turn off power before
servicing.

• TT, AIS, Radar Map, Interswitch and FURUNO’s unique Target Analyzer are supplied as stan-
dard.
• CPA/TCPA alarms.
• Targets activate the user-set alarm zone when entering or exiting the zone.
• The Target Analyzer function helps to find targets in high noise areas (rain/snow), or where
there is interference from surface reflections.
• The FAR-2xx8 series complies with MED 2014/90/EU and also the following directives:
IEC62388, IEC 62288, IMO MSC. 192(79).
Signal processing functions
This radar has the signal processing functions listed in the table below.
Terminology standards used in this manual
This manual uses the following terminology standards:
For the sake of brevity, all procedures in this manual use the terms “Open the menu.” and “Close
the menu”.
Function Description Reference
Interference rejector Suppresses interference by other radars.
Interference received simultaneously from multiple
radars may be difficult to reduce.
See
section 1.22
Echo stretch Enlarges target echoes, especially small echoes.
Suppress interference, sea clutter and rain clutter be-
fore using echo stretch, to prevent enlargement of
unwanted echoes.
See
section 1.23
Echo averaging The radar samples echoes with each scan.
Targets that show a large change with each scan are
judged as clutter and are reduced to display only
echoes from legitimate targets.
See
section 1.24
Automatic clutter elimination Discriminates clutter from the radar echo, then reduc-
es the clutter automatically.
See
section 1.25
Noise rejector Reduces white noise then improves the on-screen
S/N ratio by processing the weighted moving aver-
age filter for the received echoes in the range direc-
tion. Use this function with caution. Weak target
echoes may disappear from the screen or the range
resolution may worsen.
See
section 1.26
