SAFETY INFORMATION
"NOTIICE", "CAUTION" and "W ARNING" notices appear throughout this manual. It is the
responsibility of the operator and installer of the equipment to read, understand and follow
these notices. If you have any questions regarding these safety instructions, please contact a FURUNO agent or dealer.
This notice indicates a potentially

avoided, could result in death or
serious injury.
This notice indicates a potentially
hazardous situation which, if not
avoided, could result in minor or
moderate injury or property
damage.
This notice indicates an unsafe
practice which, if not avoided, could
result in property damage or
equipment malfunction.
DANGER
WARNING
Hazardous voltage.
Can shock, burn, or cause
death.
Only qualified personnel
should work in the unit.
Turn off the power at the
ship’s mains switchboard
before beginning the
installation. Post a warning
sign near the switchboard
to ensure the power will not
be applied while the radar
system is being installed.
Electrical shock, fire,
serious injury or death can
result if the power is not
turned off, or is applied
while the equipment is
being installed.
CAUTION
Ground both the display
unit and the antenna unit.
Ungrounded equipment can
give off or receive interference
or cause electrical shock.
Confirm that the power supply voltage
is compatible with the voltage rating
of the equipment.
Connection to the wrong power supply can
cause fire or equipment damage. The
voltage rating appears on the label at the
rear of the display unit.
Use only the supplied power cable.
Use of other power cables (particularly a
cables whose diameter is smaller than
the supplied cable) can cause fire or
short circuit.
Use the correct fuse.
Use of a wrong fuse can cause fire or
equipment damage.

NOTICE
The installation must be done by a
FURUNO representative or suitably
qualified radar technician.
Authorities require this.
The mounting location must satisfy the
following conditions:
.
Useable temperature: -15°C to 55°C
.
Out of direct sunlight

FOREWORD
Congratulations on your choice of the
FURUNO FMD-811 Radar Remote Display .
We are confident you will see why the
FURUNO name has become synonymous
with quality and reliability.
Features
Your radar has a large variety of functions,
all contained in a remarkably small cabinet.
The main features of the FMD-811 is:
• Traditional FURUNO reliability and
quality in a compact, lightweight and
low-cost.
For over 50 years FURUNO Electric Company has enjoyed an enviable reputation for
innovative and dependable marine electronics equipment. This dedication to excellence
is furthered by our extensive global network
of agents and dealers.
Your radar is designed and constructed to
meet the rigorous demands of the marine environment. However, no machine can perform its intended function unless properly
installed and maintained. Please carefully
read and follow the recommended procedures for installation, operation and maintenance.
While this unit can be installed by the purchaser , any purchaser who has doubts about
his or her technical abilities may wish to
have the unit installed by a FURUNO representative or other qualified technician. The
importance of a thorough installation cannot be overemphasized.
We would appreciate hearing from you, the
end-user, about whether we are achieving

Note: With the radar having a linear amplifier,
radar picture may not be adjusted properly
through the menu.
How to adjust the gain (sensitivity)
How to adjust STC (suppressing sea
clutter)
Echoes from waves can be troublesome,
covering the central part of the display with
random signals known as sea clutter. The
higher the waves, and the higher the scanner above the water, the further the clutter
will extend. Sea clutter appears on the display as many small echoes which might affect radar performance. (See the left-hand
figure in Figure 1-5).
The STC reduces the amplification of echoes at short ranges (where clutter is the greatest) and progressively increases
amplification as the range increases, so amplification will be normal at those ranges
where there is no sea clutter. The control is
effective up to about 4 miles.
STC can be adjusted automatically or manually . For manual adjustment, first adjust the
gain and then transmit on short range. Adjust the STC level such that the clutter is
broken up into small dots, and small targets
become distinguishable. If the setting is set
too low, tar gets will be hidden in the clutter ,
while if it is set too high, both sea clutter
and targets will disappear from the display.
In most cases adjust so clutter has disappeared to leeward, but a little is still visible
windward.
The gain works in precisely the same manner as the volume control of a broadcast receiver, amplifying the signals received.
You can adjust the gain automatically or
manually . For manual adjustment, adjust the
sensitivity on the highest range—the background noise is clearer on that range. The
proper setting is such that the background
noise is just visible on the screen. If you set
up for too little gain, weak echoes may be
missed. On the contrary excessive gain
yields too much background noise; strong
targets may be missed because of the poor
contrast between desired echoes and the
background noise on the display.

If there is no clutter visible on the display,
turn off the circuit.

How to adjust A/C RAIN
By cursor
The vertical beamwidth of the scanner is designed to see surface targets even when the
ship is rolling. However, by this design the
unit will also detect rain clutter (rain, snow,
hail, etc.) in the same manner as normal targets. Figure 1-6 shows the appearance of rain
clutter on the display.
When rain clutter masks echoes over a wide
range, raise the A/C RAIN slightly to distinguish targets from the clutter.

A/C RAIN adjusted;
rain clutter suppressed.
Operate the cursor pad to place the cursor
intersection on the inside edge of the target
echo. The range to the target, as well as the
bearing, appears at the bottom of the display.
By VRM
1) Press the [VRM] key to display the VRM.
Press the cursor pad to place the VRM
2)
on the inside edge of the target. (The cursor appears and is linked with the VRM,
allowing you to measure both range and
bearing to the target.)
3) Check the VRM readout at the bottom
left-hand corner of the display to find the
range to the target.
Note: The VRM is automatically anchored
when no cursor pad key is operated within
about 10 seconds.
Figure 1-6 Effect of A/C RAIN
Turning on/off A/C AUTO
The A/C AUTO function automatically suppresses sea clutter as well as rain clutter.
Note however that with the A/C circuit on
weak targets may be suppressed.
1.9 Measuring the Range
You can measure the range to a target three
ways: by the range rings, by the cursor , and
by the VRM (Variable Range Marker).
By range rings
Press the [RINGS] key to display the range
rings. Count the number of rings between
the center of the display and the target.
Check the range ring interval (at the top left
corner) and judge the distance of the echo
from the inner edge of the nearest ring.
To erase the VRM, press and hold down
the [VRM] key for about three seconds.

Figure 1-8 Measuring bearing by the EBL
There are two ways to measure the bearing
to a target: by the cursor, and by the EBL
(Electronic Bearing Line).
By cursor
Operate the cursor pad to bisect the target
with the cursor intersection. The bearing to
the target appears at the bottom right-hand
corner of the display.
By EBL
1) Press the [EBL] key to display the EBL.
2) Press the cursor pad to bisect the target
with the EBL. (The cursor appears and is
linked with the EBL, allowing you to
measure both bearing and range to the
target.)
3) Check the EBL readout at the bottom lefthand corner of the display to find the bearing to the target.
Tips for measuring the bearing
• Bearing measurements of smaller targets
are more accurate; the center of larger target echoes is not as easily identified.
• Bearings of stationary or slower moving
targets are more accurate than bearings
of faster moving targets.
• To minimize bearing errors keep echoes
in the outer half of the picture by changing the range scale; angular difference becomes difficult to resolve as a target
approaches the center of the display.
Target on collision course with your
vessel?
You can determine if a target might be
on a collision course with your vessel by
placing the EBL on the target. If it tracks
along the EBL as it approaches the
screen center it may be on a collision
course with your vessel.
Note: The EBL is automatically anchored when
no cursor pad key is operated within about 10
seconds.
