After the power is turned on, ST-BY(Stand-By)  
appears at the screen center.  
Procedure  
Press the ST-BY/TX key to display echoes. This  
unit displays echoes in eight intensities accord-  
ing to echo strength.  
Press the RANGE key at + or –. The range, range  
ring interval appears at the top left corner of the  
display.  
Note: "BRG SIG MISSING" may momentarily  
appear when the ST-BY/TX key is pressed just  
after the display of ST-BY at power-up. This is  
normal.  
Stand-by  
When you won’t be using the display monitor  
for an extended period, but you want to keep it in  
a state of readiness, place it in stand-by by press-  
ing the ST BY/TX key. The display shows ST-BY.  
Video lockup recovery  
Video lockup or picture freeze, can occur unex-  
pectedly on digital rasterscan radars. This is  
mainly caused by heavy spike noise in the  
power line, and can be noticed by carefully  
watching the nearly invisible sweep line. If you  
suspect that the picture is not updated every  
scan of the antenna or no key entry is accepted  
notwithstanding the apparently normal picture,  
turn the power off and on.

1.4 Presentation Mode  
Each time the MODE key is pressed, the presen-  
tation mode and mode indication at the upper-  
left corner of the screen change cyclically.  
This display monitor has the following presenta-  
tion modes:  
Relative Motion (RM)  
Head-up:  
Unstabilized  
Course-up: Compass-stabilized relative to  
ship’s intended course  
North-up: Compass-stabilized with  
reference to north  
Loss of gyro signal  
When the gyro signal is lost, the presentation  
mode automatically becomes Head-up and  
the HDG readout at the screen top shows  
xxx.x. The x's do not disappear even when the  
gyro signal is restored, to warn the operator  
that the readout may be unreliable.  
True Motion (TM)  
North-up: Ground or sea stabilized with  
compass and speed inputs  
Match the gyro readout with the gyrocompass  
reading. Press the MODE key.

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; strong targets  
may be missed because of the poor contrast be-  
tween desired echoes and the background noise  
on the display.

A common mistake is too over-adjust the A/C  
SEA control so that the surface clutter is com-  
pletely removed. By rotating the control fully  
clockwise, you will see how dangerous this can  
be; 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 gain has  
not been properly adjusted. Always leave a little  
surface clutter visible on the screen. If no clutter  
is observed (on very calm waters), set the control  
at the fully counterclockwise position.  
1.10 Suppressing Sea Clutter  
In rough weather conditions returns from the sea  
surface are received over several miles around  
own ship and mask nearby targets. This situation  
can be improved by properly using the automatic  
anti-clutter function and/or the A/C SEAcontrol.  
Automatic anti-clutter control  
The easiest way to suppress the surface clutter is  
to use the automatic anti-clutter function. Press  
the A/C AUTO switch.  
1.11 Suppressing Rain Clutter  
In adverse weather conditions, clouds, rain or  
snow produce a lot of spray-like spurious echoes  
and impairs target detection over a long distance.  
This situation can be improved by using a Func-  
tion key that is so programmed. If the Function  
key fails to effectively suppress rain clutter, use  
the A/C RAIN control.  
CAUTION  
The auto A/C function can erase weak  
targets.  
The A/C RAIN control adjusts the monitor sen-  
sitivity as the A/C SEA control does but rather in  
a longer time period (longer range). Clockwise  
rotation of this control increases the anti-clutter  
effect.  
Manual anti-clutter control  
From the fully counterclockwise position, slowly  
turn the A/C SEA control clockwise. For opti-  
mum target detection, leaves speckles of the sur-  
face return slightly visible.

Figure 1-9 Effect of A/C RAIN control  
Figure 1-8 Effect of A/C SEA control  
The anti-clutter sea facility is often referred to as  
STC (Sensitivity Time Control), which decreases  
the sensitivity, and progressively increases the  
sensitivity as the range increases.  
If the control is set 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 dis-  
play. In most cases adjust the control until clutter  
has disappeared to leeward, but a little is still vis-  
ible windward.

The heading marker indicates the ship's heading  
in all presentation modes. It appears at zero de-  
grees on the bearing scale in the Head-up mode,  
in any direction depending on the ship orienta-  
tion in North-up and True Motion modes. The  
north marker appears as a short dashed line. In  
the Head-up mode, the north marker moves  
around the bearing scale in accordance with the  
compass signal.

2) Operate the VRM control to place the outside  
edge of the VRM on the inside edge of the  
target.  
3) Check the VRM readout at the bottom right  
corner of the display to find the range to the  
target.  
To temporarily extinguish the heading marker to  
look at targets existing dead ahead of own ship,  
press the HM OFF (PUSH) control. The heading  
marker reappears when the key is released.

Erasing VRMs  
Use the range rings to obtain a rough estimate of  
the range to a target. They are concentric circles  
around own ship, or the sweep origin. The num-  
ber of rings is automatically determined by the  
selected range scale and their interval is displayed  
at the upper-left position of the screen. Press the  
RINGS (PUSH) control to show the range rings  
if they are not displayed. Successive presses of  
the RINGS (PUSH) control gradually increase  
the brightness of the rings in four steps and a fifth  
press erases the rings.  
1) If two VRMs are displayed, press the VRM  
ON key to circumscribe the VRM readout of  
the VRM you want to keep active.  
2) Press the VRM OFF key. The VRM readout  
and its associated VRM are erased.  
Note: You can select unit of range measurement  
for the cursor and VRM on the INITIAL menu.  
For further details see 1.35 Selecting Unit of  
Range Measurement, Bearing Reference.  
Measuring range by the cursor  
Rotate the trackball to place the cursor on the in-  
side edge of the target. The range to the cursor  
appears at the bottom of the display.

1.24 Interference Rejector  
Automatic speed input  
Mutual radar interference may occur in the vi-  
cinity of another shipborne radar operating in the  
same frequency band (9 GHz). It is seen on the  
screen as a number of bright spikes either in ir-  
regular patterns or in the form of usually curved  
spoke-like dotted lines extending from the cen-  
ter to the edge of the picture. This type of inter-  
ference can be reduced by activating the  
interference rejector circuit.

The interference rejector circuit is a kind of sig-  
nal correlation circuit. It compares the received  
signals over successive transmissions and sup-  
presses randomly occurring signals. There are  
three levels of interference rejection depending  
on the number of transmissions that are corre-  
lated. These are indicated by the legends IR1, IR2  
and IR3 at the bottom right-hand position of the  
screen.  
True motion trails require a gyrocompass signal  
and own ship speed input to cancel out own ship's  
movement and present true target movements in  
accordance with their over-the-ground speeds and  
courses (not heading). Refer to the automatic and  
manual speed input procedures for entering own  
ship's speed information.  
To turn on or off the interference rejector circuit;

How to turn on echo averaging  
1.28 Watch Alarm  
To properly use the echo average feature, first  
properly suppress sea clutter with the A/C SEA  
control and then select echo average function as  
follows;  
The watch alarm works like an alarm clock,  
sounding an aural alarm and blinking a visual  
indication “T ALM” at the predetermined time  
interval. When the alarm sounds, you can silence  
it by pressing the AUDIO OFF key.  
1) Press the MENU key.  
2) Select the ECHO SIG menu.  
3) Press the ENTER/SELECT key.  
You can select time interval (3 min, 6 min, 12  
min, 15 min, or 20 min) on the TIME ALM menu.  
1) Press the MENU key.  
4) Select ECHO AVG and press the ENTER/SE-  
LECT key.  
2) Select the TIME ALM menu.  
3) Press the ENTER/SELECT key.  
5) Select 1, 2, or 3.  
1: Distinguishes targets from sea clutter and  
suppresses brilliance of unstable echoes.  
4) Select TIME ALM and press the ENTER/SE-  
LECT key.  
2: Distinguishes small stationary targets such  
as navigation buoys.  
5) Select time interval (or OFF).  
6) Press the ENTER/SELECT key.  
7) Press the MENU key.  
3: Displays distant targets as stable echoes.  
6) Press the ENTER/SELECT key.  
7) Press the MENU key.  
1.29 Echo Average  
The echo average feature effectively suppresses  
sea clutter and other random noise. Echoes re-  
ceived from stable targets such as ships (if not  
moving at high speeds) appear on the screen at  
almost the same position every rotation of the  
antenna. On the other hand, unstable echoes such  
as sea clutter appear at random positions.  
a) Echo average OFF  
b) Echo average 1  
To distinguish real target echoes from sea clutter,  
this radar performs scan-to-scan correlation. Cor-  
relation is made by storing and averaging echo  
signals over successive picture frames. If an echo  
is solid and stable, it is shown in its normal in-  
tensity. Sea clutter is averaged over successive  
scans and reduced in brightness. This makes it  
easier to discriminate real targets from sea clut-  
ter.  
Figure 1-25 Echo average  
CAUTION  
Do not use the Echo Average feature under  
heavy pitching or rolling; loss of true  
targets can result.  
1 – 23  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Echo averaging uses scan-to-scan signal correla-  
tion technique based on the true motion over the  
ground of each target. Thus, small stationary tar-  
gets such as buoys will be shown while suppress-  
ing random echoes such as sea clutter. True echo  
average is not however effective for picking up  
small targets running at high speeds over the  
ground.  
1.31 Echo Stretch  
On long ranges target echoes tend to shrink in  
the bearing direction, making them difficult to  
see. On short and medium ranges such as 1.5, 3  
and 6 nm range scales, the same sized targets get  
smaller on screen as they approach own ship.  
These are due to the inherent property of the ra-  
diation pattern produced by the antenna. To en-  
hance target video, use the echo stretch feature.  
The echo average feature is inoperable when a  
heading signal is not available. If you wish to use  
this feature without a heading signal, system ini-  
tialization is required. (Consult a FURUNO rep-  
resentative or dealer.)  
Enlarged in range  
direction by ES 2  
Enlarged by ES 1  
Note: Echo averaging also requires ship's speed  
information from a log or manual entry.  
If a target becomes  
smaller as it approaches  
own ship, use ES 1.  
If a distant target  
is hard to see,  
use ES 2.  
1.30 Suppressing Second-Trace  
Echoes  
ECHO STRETCH 1  
For stretching echoes

ECHO STRETCH 2  
For stretching echoes near  
perimeter of CRT  
In certain situations, echoes from very distant  
targets may appear as false echoes (second-track  
echoes) on the screen. This occurs when the re-  
turn echo is received one transmission cycle later,  
namely, after a next radar pulse has been trans-  
mitted.

Note 1: Echo stretch magnifies not only small  
target pips but also returns from sea surface, rain  
and radar interference. For this reason, make sure  
that these types of interference have been suffi-  
ciently suppressed before activating the echo  
stretch feature.  
5) Select ON.

3 nm scale for M1 (0.3 µs), the echo stretch fea-  
ture is not available on these range scales.

MAINTENANCE  
Periodic checks and maintenance are important for proper operation of any electronic systems. This  
chapter contains maintenance instructions to be followed to obtain optimum performance and the  
longest possible life of the equipment.  
Danger!-Electrical Shock Hazard  
This equipment contains high voltages which can endanger human life at several  
internal circuits including a cathode ray tube (CRT) which uses several thousands  
volts. Any internal adjustment, servicing and repair shall only be performed by  
qualified service personnel totally familiar with electrical circuits and servicing of  
the equipment. A residual charge remains in capacitors and other devices several  
minutes after turning off the power. It is therefore essential to wait at least 3 min-  
utes to allow residual charge to subside before accessing the inside of the equip-  
ment. Special care must be taken when approaching the following parts:  
• Power supply circuit (Display unit)  
• CRT circuit (Display unit)

2.3 Replacing the Fuse  
ARP-15 data appears  
if ARP-15 is provided.  
The fuse in the power cable protects the equip-  
ment against reverse polarity of ship’s mains,  
overcurrent, and equipment fault. If the fuse  
blows, find the cause before replacing it. Use the  
proper fuse shown in below, since overfusing can  
cause serious damage to the equipment and void  
the warranty.

• The display unit should be oriented so that  
you can view the screen while facing to-  
wards the bow. This will make determina-  
tion of your position easier.  
Chapter 3  
Installation  
• The mounting location must be strong  
enough to support the display unit under  
vibration conditions normally encountered  
on the vessel. If necessary reinforce the  
mounting location.  
DANGER  
This equipment uses high  
voltage electricity which  
can shock, burn or cause  
death.  
• Determine the mounting location consid-  
ering the length of the signal cable, which  
connects between the main radar and this  
display unit.  
Only qualified personnel  
should work inside the  
equipment.  
• Make sure you allow enough clearance to  
get to the connectors behind the unit. Leave  
at least a foot or so of “service loop” in  
cables so that it can be pulled forward for  
servicing or easy removal of the connec-  
tors.  
3.1 Mounting the Display Unit  
Siting considerations  
• The display unit can be mounted on a table-  
top, a bulkhead or on the overhead. Install  
it where it can be viewed and operated con-  
veniently, but where it is protected from  
being sprayed or immersed in salt or fresh  
water.  
Tabletop mounting  
1) Unfasten the two M8 x 40 bolts at the front  
of the display unit. Remove the fixing plate.  
2) Mark screws locations in the tabletop by  
using the fixing plate as a template. For  
mounting by bolts and nuts, drill four  
holes of 12 mm diameter in the tabletop.  
• Observe the following display unit com-  
pass safe distances to prevent deviation of  
the magnetic compass;  
3) Secure the fixing plate to the tabletop by  
ø9 coach screws or M10 bolts, nuts and  
washers.  
Table 3-1 Display unit compass safedistances  
4) Lay the display unit on the fixing plate. Se-  
cure it with the two M8 x 40 bolts unfas-  
tened in step 1.
