1. OPERATION

1.3 Turning Power On/Off

Press the [POWER/BRILL] key to turn on the
power. The unit beeps, the startup screen
appears, and then the equipment checks the
ROM and RAM for proper operation and
displays program number. The ROM and
RAM check shows OK or NG (No Good). If
NG appears, try to press any key except the
[POWER/BRILL] key to start operation.
However, the equipment may not work
properly. Contact your dealer for advice.

7" LCD MARINE RADAR

MODEL 1715

FURUNO ELECTRIC CO., LTD.

ROM : OK RAM : OK
Program No: 0359199-XX.XX

XX.XX = Program version no.

Startup screen

After the completion of the startup test, a
timer displays the time remaining for warm up
of the magnetron (the device which transmits
radar pulses), counting down from 1:00 to
0:00.

To turn off the power, press and hold down
the [POWER/BRILL] key (about three
seconds) until the screen goes blank.

Provided that the radar was once in use with
the transmitter tube (magnetron) still warm,
you can turn the radar into TRANSMIT
condition without 1-minute of warm-up. If the
[POWER/BRILL] switch was accidentally
turned off and you want to restart the radar
promptly, turn on the [POWER/BRILL] switch
not later than 15 seconds after power-off.

Note 1: In a cold environment the screen
appears “foggy” when the power is turned on
but is soon restored to normal condition.

Note 2: The example screens shown in this
manual may not match the screens you see
on your display. The screen you see depends
on your system configuration and equipment
settings.

1.4 Transmitting, Standby

After the power is turned on and the
magnetron has warmed up, “ST-BY”
(Stand-by) appears, indicating the radar is
ready to transmit radar pulses.

To toggle between transmit and stand-by, do
the following:

1. With the power turned on, press the
[POWER/BRILL] key momentarily to show
the brilliance/contrast adjustment window.

2. Press the [MODE] key to go to stand-by

and transmit status alternately.

Note: If you attempt to transmit before
“ST-BY” appears, the beeps sound and
the radar does not transmit pulses. Wait
until “ST-BY” appears.

3. Press the [MENU/ESC] key to close the

window.

When radar pulses are transmitted the radar
receiver is automatically tuned. Echoes
appear in four levels of digitized video
according to echo strength. When a target is
beneath a marker (VRM, EBL, heading line,
range ring) the part of the marker where the
target lies is displayed in reverse video.

1.7 Receiver Sensitivity

The [GAIN] key adjusts the sensitivity (gain)
of the receiver. It works in precisely the same
manner as the volume control of a broadcast
receiver, amplifying the signals received.

To set the sensitivity, you first choose the
automatic sensitivity setting which best
matches current sea condition. Then, if
necessary, you may fine tune the sensitivity
manually. The proper setting is such that the
background noise is just visible on the
screen.

If you set up for too little sensitivity, weak
echoes may be missed. On the other hand
excessive sensitivity yields too much
background noise; weak targets may be
missed because of the poor contrast between
desired echoes and the background noise on
the display.

the display shown below appears.

tuning bar, press ◄ or ► to adjust the
gain. The setting range is 0-100.

3. Press the [MENU/ESC] key to finish.

1.8 Suppressing Sea Clutter

In rough weather, returns from the sea
surface, called sea clutter, are received over
several miles around own ship and mask
nearby targets. This situation can be
improved by properly suppressing the sea
clutter with the A/C SEA control.

To set the A/C SEA, you first choose the
automatic A/C SEA setting which best
matches current sea conditions. Then, if
necessary, you may fine tune the A/C SEA
manually.

In most cases suppress the clutter until it has
disappeared to leeward, but a little is still
visible windward. If the setting is too low,
targets will be hidden in the clutter, while if it
is set too high, both sea clutter and targets
will disappear from the display.

A common mistake is too over-suppress sea
clutter so that it is completely removed. You
can see how dangerous this can be by setting
up for maximum A/C SEA: A dark zone will be
created near the center of the screen,

causing a loss of close-in targets. This dark
zone is even more dangerous if the sensitivity
has not been properly adjusted.

Always leave a little sea clutter visible on the
screen, first adjusting automatically and then
fine tuning with the manual control as
necessary.

4. Press the [MENU/ESC] key to finish.

1.9 Suppressing Rain Clutter

The vertical beamwidth of the antenna is
designed to see surface targets even when
the ship is rolling. However, by this design the
antenna will also pick up rain clutter (rain,
snow, or hail) in the same manner as normal
targets. The illustration below shows the
appearance of rain clutter on the display.

The A/C RAIN control adjusts the receiver
sensitivity as the A/C SEA control does but
rather in a longer time period (longer range).
The higher the setting the greater the
anti-clutter effect.

Rain clutter at screen center

in the same frequency band (9 GHz). It is
seen on the screen as a number of bright
spikes either in irregular patterns or in the
form of usually curved spoke-like dotted lines
extending from the center to the edge of the
picture. This type of interference can be
reduced by activating the interference rejector
circuit. “IR” and the rejection level indicator
“L,” “M” or “H” appear at the top right corner
when the interference rejector circuit is on.

1. OPERATION

1.20 Guard Alarm

The guard alarm allows the operator to set
the desired range and bearing for a guard
zone. When ships, islands, landmasses, etc.
violate the guard zone, audio and visual
alarms are released to call your attention.
The alarms will be released for targets
entering or exiting the zone depending on the
presence or absence of targets in the zone
when the alarm is set.

NOTICE

The alarm should not be relied upon as the

*

sole means for detecting possible collision
situations.

A/C SEA, A/C RAIN, FTC and GAIN controls

*

should be properly adjusted to be sure the
weak echoes will not be missed by the alarm.

How guard zone type is determined

After the guard zone has been set, the radar
checks for targets inside the guard zone,
which takes about 8 to 12 seconds. When the
check is completed, “G(IN)” or “G(OUT)”
replaces G(---) at the top right corner.

G(IN): When no target exists in the zone,
"G(IN)" appears. The audio alarm sounds
against targets which enter the guard zone.
G(OUT): If there are targets in the guard
zone, "G(OUT)" appears. The audio alarm
sounds against all targets which exit from the
guard zone.

Setting a guard zone

1. Operate the cursor pad to place the
cursor at the top left corner for the zone
and then press the [ALARM] key.

2. Operate the cursor pad to place the
cursor at the bottom right corner for the
zone and then press the [ALARM] key.

Silencing the audio alarm

When a target violates the guard zone, the
target flashes and the audio alarm sounds.
You can silence the audio alarm with the
[ALARM] key. The target continues flashing
until it no longer violates the guard zone or
the guard zone is canceled.

1. OPERATION

1.21 Watchman

The radar "wakes up" at specified time
intervals (5, 10, or 20 minutes) and operates
for 10 scans, the start of which is announced
by releasing the audio alarm. If change is
found in the guard zone from the previous 10
scans, the audio alarm sounds and the radar
resumes normal operation, canceling the
watchman mode. If no change is found, the
radar goes into stand-by, for the specified
time interval. This feature is useful for
periodic watch of the guard zone.

EBL REFERENCE: The EBL readout may be

chosen from relative (relative to own ship’s
heading) or true (referenced to the North).
Heading data required for true bearing.

Note: If no bearing data is input, course data
from the GPS navigator is used. In this case
ship’s speed must be more than two knots.

BEARING READOUT: Course indication may
be shown in true or magnetic (magnetic
compass) degrees. Heading data required for
true degrees.

CURSOR POSITION: Chooses the
information to show for the cursor position:
latitude and longitude or range and bearing
from own ship. Latitude and longitude
position requires a navigator.

TRIP SOURCE: Chooses the criteria for
calculating distance run: latitude and
longitude or speed. Requires navigator or
speed log.

WIND SPD/DIR: True is the speed and
direction (in relation to ship’s bow) of the wind
felt or measured when stationary. Apparent
is the direction (in relation to ship’s bow) and
speed of the wind as it appears to those on
board, relative to the speed and direction of
the boat; combination of the true wind and the
wind caused by the boat’s movement.
Requires wind data.

SHIFT MODE: Own ship position, or sweep
origin, can be displaced manually or
automatically. For automatic displacement,
the amount of shift is calculated with ship
speed, and the amount is limited to 60% of
the range in use. For example, if the “Auto
Shift Speed” setting is 15 knots and the ship
is running at 10 knots, the amount of shift will
be about 40%. The formula for determining
shift amount is as below. Requires speed
data.

AUTO SHIFT SPEED: Sets the automatic
shift maximum speed. The setting range is
1-99.

TX SECTOR BLANK: In some installations it
may be unavoidable to locate the antenna
where an object (mast, etc.) will prevent
transmission within its breadth. You should
disable transmission within this area by
turning on this feature and setting the area
with BLANKING START and BLANKING

Check for foreign material.
(Foreign material on the
antenna unit can cause a
considerable drop in
sensitivity.)

Check for cracks. Permanent
damage to the unit’s circuitry
will result if water leaks inside.

The display case and LCD will,
in time, accumulate a coating
of dust, and dust on the LCD
tends to dim the picture.

Check for tight connection and
corrosion.

Replace corroded bolts. Coat new
bolts with anticorrosive sealant.

Clean the antenna unit with a
freshwater-moistened cloth.
Alcohol may be used. Do not use
commercial cleaners to clean the
antenna unit; they can remove
paint and markings or deform the
equipment.

If a crack is found, it should be
temporarily repaired by using a
small amount of sealing compound
or adhesive. The unit should then
be brought to your dealer for
permanent repairs.

Wipe the LCD carefully to prevent
scratching, using tissue paper and
an LCD cleaner. To remove dirt or
salt deposits, use an LCD cleaner,
wiping slowly with tissue paper so
as to dissolve the dirt or salt.
Change paper frequently so the
salt or dirt will not scratch the LCD.
Do not use commercial cleaners to
clean the display unit; they can
remove paint and markings or
deform the equipment.

If corroded, ask your dealer about
replacement.

3. INSTALLATION

3.1 Antenna Unit Installation

Mounting considerations

When choosing a mounting location for the
antenna unit, keep in mind the following
points:

•

Install the antenna unit on the hardtop,
radar arch or on a mast on an appropriate
platform. (For sailboats, a mounting bracket
is optionally available.) It should be placed
where there is a good all-round view with,
as far as possible, no part of the ship’s
superstructure or rigging intercepting the
scanning beam. Any obstruction will cause
shadow and blind sectors.

•

In order to minimize the chance of picking
up electrical interference, avoid where
possible routing the antenna cable near
other electrical equipment onboard. Also,
avoid running the cable in parallel with
power cables.

•

Separate the antenna unit from a magnetic
compass by the distances noted below to
prevent interference to the magnetic
compass:

Standard compass: 1.25 m
Steering compass: 0.85 m

Mounting on a platform

1. Remove mounting hardware at the bottom
of the antenna unit; four each of hex bolts
(M10X20), spring washers and flat
washers. Save mounting hardware to use
it to fix the antenna unit to the mounting
platform later on.

Stern

Cable gland

Hex bolt (M10 x 20)

2. Construct a platform (wood, steel, or
aluminum) of 5-10 mm in thickness
referring to the outline drawing at back of
this manual. Fasten the platform to the
mounting location. Next, position the
antenna unit so the cable gland faces
toward boat’s stern.

Note 1: If corrosive material is used for
the platform, take appropriate
anticorrosive measures to prevent
corrosion.
Note 2: When drilling holes in the platform,
be sure they are parallel with the fore and
aft line.

3. Using the hex bolts, flat washers and
spring washers removed at step 1, fasten
the antenna unit to the platform. The

torque should be between 19.6-24.5
N////m.

Note: Longer hex bolts (M10 x 25) are

supplied with the installation materials.
Use them instead of the hex bolts
removed earlier if the thickness of the
mounting platform is 5-10 mm.

3.4 Adjustments

After you have installed the radar, do the
heading alignment and timing adjustment. If
you are connecting external equipment,
follow “NMEA port setup, GPS WAAS setup”
(for GP-320B) also.

Heading alignment

You have mounted the antenna unit facing
straight ahead in the direction of the bow.
Therefore, a small but conspicuous target
dead ahead visually should appear on the
heading line (zero degrees).

In practice, you will probably observe some
small error on the display because of the
difficulty in achieving accurate initial
positioning of the antenna unit. The following
adjustment will compensate for this error.
