FOREWORD

A Word to FCV-1200L/1200LM Owners
Congratulations on your choice of the FURUNO FCV-1200L/FCV-1200LM COLOR LCD
SOUNDER. We are confident you will see why the FURUNO name has become synonymous
with quality and reliability.
FCV-1200L is a dual-frequency color LCD sounder, and FCV-1200LM is a monitor which
displays the signal from an external video sounder.
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.
This equipment is designed and constructed to meet the rigorous demands of the marine
environment. However, no machine can perform its intended function unless installed, operated
and maintained properly. Please carefully read and follow the recommended procedures for
operation and maintenance.
We would appreciate hearing from you, the end-user, about whether we are achieving our
purposes.
Thank you for considering and purchasing FURUNO equipment.
Features
8- or 16- color presentation (including background) provides detailed information on fish
density and bottom composition, on a 10.4 inch color LCD.
Furuno Free Synthesizer (FFS) transceiver design allows use of user-selectable operating
frequencies.
You can select display orientation; Portrait (vertical) or Landscape (horizontal).
Automatic bottom tracking features permits unattended operation.
Frequency mixing picture helps discriminate fish species.
Alarms: Fish, Bottom, Fish-Bottom, Water Temperature (temperature data required).
A-scope presentation displays echoes at each transmission with amplitudes and colors
according to intensities.
Unique split range control allows independent range settings in dual-frequency mode.

You can select through the menu. See page 2-3.
BOTTOM LOCK
The bottom lock display shows the area between the zoom marker and the bottom as a straight line to distinguish it from fish near the bottom, and thus it is useful for discriminating fish near the bottom.

This mode compares echo intensity between low and high frequencies, and displays echoes from tiny fish in discriminative colors. This is done by utilizing the fact that tiny fish return a stronger echo against a high frequency rather than a low frequency. This is done as below.
1. If a high frequency echo is stronger than the corresponding echo on the low frequency, the high frequency echo is displayed.
2. If the low frequency echo is stronger than or equal to the high frequency echo, it is less likely to be a tiny fish and therefore is displayed in blue.
3. If the echoes on both frequencies have the intensity corresponding to reddish brown or red, they are displayed in reddish brown or red: this is necessary to display the zero line and bottom in reddish brown or red.
In other words, the echoes displayed in orange thru light-blue may be considered to be tiny fish such as whitebait.

Ship’s speed dependent mode
With speed data provided by a speed log, current indicator or navigation equipment, the display advance speed may be set according to ship’s speed, the ship’s speed dependent mode. As shown in the figure below the horizontal scale of the display is not influenced by the change of ship’s speed, thus the speed-dependent picture advance permits j udgement of fish school size and abundance at any speed. The picture advance speed indication is suffixed with an “S” when the ship’s speed dependent mode is active. For exam ple, “1/1S.” For how to enable the ship’s speed dependent mode see page 2-9. T his funct ion is available with ship’s speed of 2-20 kt.

PRR LEVEL
Changes pu lse repetition rate. Normally, the highest rate (20) is used. When in shallow waters second reflection echoes may appear between surface and actual bottom echo. In this case lower the PRR level.
The choice “S” means the ship’s speed dependent mode, where the PRR changes automatically with ship’s speed. (Requires ship’s speed input.) For further information about the ship’s speed dependent mode, see page 1-20.
STC (High and Low Frequencies)
Adjusts STC level for the high and low frequencies, and is useful for suppressing surface noise. The setting range is 0-10; the higher the setting the greater the extent of suppression. Setting 10 suppresses noise up to about 5 m. Turn off the STC when there is no noise on the screen, otherwise weak echoes may be missed.

4.3 Bottom Echoes

Bottom echoes are normally strongest and displayed in reddish brown or red, but colors and width will vary wit h bottom material, depth, sea condition, installation, frequency, pulselength and sensitivity.
Bottom prof ile
A hard and rough bottom appears with a longer tail because it reflects more of the ultrasonic pulse. Because of their stronger return, shallow echoes appear wider than deep ones even when all botom conditions are equal. Also, a longer bottom tail appears on slopes because of the difference in traveling time at both edges of the beam angle. In the rugged bottom, echoes are reflected on many different planes, overlapping to present a 3D effect.

Color difference
Second bottom echo
Rugged bottom
Bottom material and bottom profile
Page 69
Bottom nature
The nature of the bottom is known from the intensity and length of the bottom tail. Generally,
when observing the bottom nature, the lower sounding frequency is used, the pulselength is set
to long, and the gain setting is not disturbed. In the hard and craggy bottom, the bottom appears
more reddish and with a long tail. However, the bottom with a sediment may give a short tail if a
low frequency sounding is used.

4.4 Fish Schools

Fish quantity
Fish quantity can be estimated to a certain extent from fish echoes on the screen if fish school
size and fish school density are kept in mind.
Fish school size
Usually the size of fish echoes on the screen is proportional to the actual size of the fish school.
However, if two fish echoes appear at different depths with the same size, the fish school at
shallower depth is smaller because the ultrasonic beam widens as it propagates and a fish
school in deep water is displayed larger.

Small school

Page 70
Fish school density
If two fish scools appear with the same color at different depths, the one in deeper water is
denser because the ultrasonic wave attenuates as it propagates and the fish school in deep
water tends to be displayed in a weaker color.

Aerated water
When the sea is rough or the ship makes a quick turn, gaps in the bottom echo on the screen may appear. This is caused by air bubbles which block propagation of the sound wave. Generally low frequency ultrasonic waves are interrupted more easily than high ones.

TROUBLESHOOTING
WARNING
ELECTRICAL SHOCK HAZARD Do not open the equipment.
Only qualified personnel should work inside the equipment.

5.1 Maintenance

Regular maintenance is important for continued performance. Important points to be checked from time to time are shown below.
Check point Action Interval Transducer cable If conductors are exposed, replace cable. Monthly Power cable plug, transducer cable plug If loosened, secure tightly. Monthly Grounding If corroded, clean. Monthly Ship’s mains voltage If out of ratings, correct problem. Mont hly Transducer cleanliness Marine life on the transducer will result in a
gradual decrease in sensitivity. Check the transducer face each time the boat is drydocked. Carefully remove any marine life with piece of wood or fine sandpaper.
Display unit cleanliness Dust or dirt may be removed with a soft
cloth. Water-diluted mild detergent may be used if desired. DO NOT use chemical cleaners to clean the display unit; they may remove paint and markings.
LCD screen 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 solvents such as thinner, acet one or benzene for cleaning.
