ELECTRICAL SHOCK HAZARD
WARNING
Keep heater away from equipment.
Do not open the equipment.
Only qualified personnel
should work inside the
equipment.
A heater can melt the equipment's power
cord, which can cause fire or electrical
shock.
Use the proper fuse.
Immediately turn off the power at the
switchboard if water leaks into the
equipment or something is dropped in
the equipment.
Continued use of the equipment can cause
fire or electrical shock. Contact a FURUNO
agent for service.
Do not disassemble or modify the
equipment.
Fire, electrical shock or serious injury can
result.
The fuse in the hull and transceiver units
protects them from overvoltage, equipment
fault and reverse polarity of the ship's
mains. If a fuse blows replace it with fuse of
the same amperage. Use of a wrong fuse
can result in damage to the equipment.

FOREWORD
Thank you for purchasing the CH-300 Dual-Frequency Searchlight Sonar. We are confident
you will discover why FURUNO has become synonymous with quality and reliability.
Dedicated in the design and manufacture of marine electronics equipment for half a century,
FURUNO Electric Company has gained an unrivaled reputation as a world leader in the
industry. This is the result of our technical excellence as well as our worldwide distribution
and service network.
Please carefully read and follow the safety information and operating and maintenance
instructions set forth in this manual before attempting to operate the equipment and conduct
any maintenance. Your sonar will perform to the utmost of its ability only if it is operated and
maintained in accordance with the correct procedures.
Features
The CH-300 is a dual-frequency searchlight sonar. Consisting of a monitor unit, control unit,
transceiver unit and hull unit, it displays underwater objects on the monitor of choice, in 8 or
16 colors according to received echo strengths.
The main features are
• Horizontal and vertical section modes for detecting, searching, tracking and monitoring
fish school.
• 12 display modes for virtually any fishing application.
• Mix mode discriminates small fish.
• Fish or bottom echo can be displayed in white to distinguish bottom fish.
• Hull unit automatically raises the transducer when ship’s speed exceeds prescribed
speed.
• User-programmed function keys provide one-touch access to desired function.
• Two types of target lock for effective tracking of fish school.
• Digital display of position, speed, course, water temperature, depth, tide speed and
direction. (Requires appropriate sensors.)
vi
Usage Precautions
• The Motion Sensor MS-100 compensates for ship’s pitching and rolling. However, it does
not compensate for load unbalance.
• If the equipment will not be used for a long time, shut off the power to it at the mains
switchboard, to prevent battery discharge.
• If the soundome is to be operated while the ship is dry-docked, set the transmitter output
power to “minimum” (on the COM1 menu). Damage to the train-tilt section may result if it
is operated with maximum transmitter power while the ship is dry-docked.
• When the ship is dry-docked check for signs of corrosion on the soundome. Find the
reason for the corrosion and attach a zinc plate to the hull unit as an anticorrosion
measure if necessary.
Notice
• No part of this manual may be copied or reproduced without written permission.
• If this manual is lost or worn, contact your dealer about replacement.
• The contents of this manual and equipment specifications are subject to change without
notice.
• The example screens (or illustrations) 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.
• This manual is intended for use by native speakers of English.
• FURUNO will assume no responsibility for the damage caused by improper use or
modification of the equipment or claims of loss of profit by a third party.

Mix Display
The mix display 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. The equipment
accomplishes this as follows:
• If a high frequency echo is stronger than the corresponding echo on the low frequency,
the high frequency echo is displayed.
• 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.
In other words, the echoes displayed in orange thru light-blue may be considered to be tiny
fish such as whitebait. When the mix display is active the indication MX appears at the top
of the display.

1. OPERATIONAL OVERVIEW
To use the mix display effectively, it is important that the gain for both the low and high
frequencies is set properly. When searching for young fish such as whitebait, follow the
procedure below. For detailed information about gain adjustment, see the next section.
Gain adjustment
1. Adjust the high-frequency gain while observing targeted fish.
2. While observing the mix display, set the low-frequency gain to 0 and gradually raise it
just until echoes from adult fish disappear from the mix display.
3. While observing the echoes from young fish on the mix display, readjust the
low-frequency gain in order to distinguish young fish. When the echoes from young fish
are weak, lower the low-frequency gain. If adult fish appear, raise the low-frequency
gain. (Rule of thumb: For whitebait, low-frequency gain is set 3-4 steps lower than
high-frequency gain.)
To activate the mix mode, press the MIX key. How to display the mix display depends on the
display mode in use.

Choosing a Tilt Angle
The tilt angle shown the direction to which the sound wave is emitted. When the sound
wave is emitted horizontally, the tilt angle is said to be 0° and when emitted vertically, 90°.
To set a tilt angle, operate the TILT control. Watch the tilt angle indication and tilt angle
indicator at the top right corner of the screen. The tilt angle can be set in increments of 1°
from 0° to +5° (upward) to 0° to 90° (downward). Choose tilt angle depending on target fish.
For surface fish choose a narrow angle (about 5°) and for bottom fish, a wide angle (about
40°).

Tilt angle for surface fish
Sound emitted from the sonar transducer forms an oval-shaped beam with a width of
approximately 10° (–3 dB, full scan, vertical beam width on 85 kHz) in the vertical direction
(vertical beam width). The tilt angle is indicated by the angle between the center line is
parallel with the sea surface and one half of the emitted sound goes upward, toward the sea
surface. This causes one half of the emitted sound to be reflected toward the transducer
and displayed on the screen as sea surface reflections. When the sea is calm, since the
sound is reflected just like reflections become negligible.
However if the sea is not calm enough, they will become dominant and interfere with
observation of wanted echoes. To minimize these sea surface reflections and to search fish
schools effectively, the tilt angle is usually set between 5° and 7° so the upper portion of the
beam becomes almost parallel with the sea surface. When the sea is rough, the tilt angle is
slightly increased to lessen the affect of sea surface reflections.

Distinguishing fish echo from bottom echo in coastal waters
In coastal operations the bottom reflection is prominent so it is important to be able to
distinguish fish echoes from the bottom echo. The information below will help you to do this.
Tilt angle and bottom echo
Case 1 - Tilt angle 30° to 40°: The bottom echo, captured by the vertical beam width (10°
at -3dB full circle, 85kHz), is displayed “ring-shaped” and in strong colors.
Case 2 - Tilt angle 10° to 20°: The bottom echo is displayed wider and in weak colors as
the distance to the bottom increases.
Case 3 - Tilt angle 0° to 5°: The bottom echo is either weak or is not displayed even if the
vertical beam width captures the bottom echo, because the distance to the bottom is too far.

Fish school “a” and “b” are just above the bottom echo.
Fish school “b” is clearly seen. Fish school “a” is behind
the bottom echo therefore it is difficult to discern.
Bottom echo is weak so fish school “b” is easily seen.
Fish school “a” is masked by the bottom echo so it is
difficult to discern. However, larger fish schools may
appear in this condition.

Displaying weak echoes clearly
Echoes from targets (such as the bottom or a fish) return to the transducer in order of the
distance to them, and when their intensities are compared at the transducer face, those
from nearer targets are generally stronger when their reflecting properties are nearly equal.
The sonar operator will be quite inconvenienced if these echoes are directly displayed on
the screen, since he won’t be able to judge the actual size of the target from the size of
echoes displayed on the screen. To overcome this inconvenience, use the TVG function. It
compensates for propagation loss of sound in water: amplification of echoes on short range
is suppressed and gradually increased as range increases, so that similar targets are
displayed in similar intensities irrespective of the ranges to them.
The TVG also functions to suppress unwanted echoes and noise which appears in a certain
range area on the screen.

TVG LEVEL: Compensates for propagation loss of sound in water. Default setting is 4.0.
For further details, see paragraph 2.12.3.
TVG DISTANCE: As above. Default setting is 4.0.
RES. COLOR: Sets transfer characteristics of input signal level versus display echo level.
Echo strength is emphasized in order of CUBE, SQUARE, LINEAR, LOG, and you can
observe the characteristics of each by watching the color bar as you change the setting.
LOG:
Displays weak to strong echoes in their respective levels. This is the default
setting,
and is suitable for general use.
LINEAR: Downplays the weak echoes when compared with LOG. Effective for suppressing
weak echoes such as plankton.
SQUARE: Strong echoes are emphasized more than in LINEAR.
CUBE:
Strong echoes are emphasized even more than in SQUARE.
CLUTTER: Low intensity echoes, often caused by sediments in water, are painted on the
screen as a large number or random dots. This noise can be suppressed. The higher the
number (setting) the weaker the echoes which are erased.

TARGET KEY: Chooses target lock function between position and echo. Default setting is
ECHO. For further details see paragraph 2.13.
LOCK MODE: Chooses how to track fish echo in ”echo” target lock; automatically or
manually. Default setting is AUTO. For further details see paragraph 2.13.
AUTO TILT: Turns automatic tilt on or off, and the default setting is OFF. The choices are
±2°, ±4°, ±6°, and ±10°. Automatic tilt adjusts the tilt angle in the following sequence:
B → (B-A) → B → (B+A) → B → (B-A) → B → (B+A)…
B: Current tilt angle
A: Auto tilt setting
For example, the tilt angle is 30° and the automatic tilt setting is 4°. Then, the tilt angle is
changed in the following sequence: 30° → 26° → 30° → 34° → 30°→ 26° → 30° → 34°…

2.15 Interpreting the Horizontal Display
This section provides information necessary for interpreting the horizontal display.
2.15.1
How the horizontal mode picture is painted
The wide sounding beam is emitted from the soundome at a certain tilt angle (see hatched
area in the figure below). The information (target echoes) obtained by this beam is
displayed in sectors of increments of 12° of the screen. Thus, all directions around the boat
are sounded in 30 times of transmissions.
Note: When the “FAST SCAN” is switched off, the equipment operates in a narrow
sounding beam. Then, the echoes appear on a 6° sector in each transmission, so 60
transmissions are required to complete the full 360° picture (6°x 60=360°). This means that
training speed is slower. However, since transmission power is concentrated into the narrow
sounding beam, a superior detection range is obtained. Furthermore, since the bottom
contour is painted distinctly, bottom fish may be more easily detected.

Sample displays
This section provides various examples of horizontal mode displays. The appearance of
actual fish echoes will vary according to factors such as transmission frequency, gain and
TVG settings, and bottom composition and contour.
Bottom echoes
When the tilt angle is changed, the bottom echo illustrated below will appear on the display.
When the tilt is decrease (toward 0°), the bottom trace becomes winder and weaker. By
observing the bottom condition on the display, the skipper can prevent net damage.
(A) Flat bottom
Tilt angle: 10° to 15°
Decreased tilt angle
Only half of
vertical beam width
captures the bottom.
(B) Flat bottom
Tilt angle: 20° or more
(C) Sloping bottom
Bottom is displayed
narrower and in
stronger colors when
compared to (A).

Fish schools
A fish school appears as a mass of echoes on the screen. The color of the mass shows the
density of fish schools on the sonar beam. To find distribution and center point of a fish
school, try several different tilt angles.

Sea surface reflections
To reduce sea surface reflections, set the tilt angle to 5° or higher, so the upper edge of the
sonar beam does not hit the sea surface, or adjust TVG. When a decreased tilt angle is
used, sea surface reflections cover a large area as illustrated below.

Sidelobe echo (false echo)
An ultrasonic wave is emitted only in the direction set by the TILT control, however there are
some emissions outside the main beam. These are called sidelobes. The energy of the
sidelobe is fairly weak but when the water is comparatively shallow and the bottom is rocky
and hard, strong signals are detected by the sidelobe. These are represented on the display
as a false echo as shown below.
Mainlobe echo
Sidelobe

The bottom echo
detected by sidelobe
appears at a certain
tilt angle when the
sidelobe points vertically. Also, poor
soundome projection
may result in a similar
false echo.
Sidelobe echoes
Noise
When the fishing ground is crowded with many fishing boats, the sonar is subject to
interference from ultrasonic equipment (echo sounder or sonar) on other boats as well as
those on own ship.
For instance, interference from the sonar operated on other boats will show itself on the
display as in the figure below. This interference can be suppressed by changing the Tx rate
on the COM1 menu.

plotter’s range is much longer. For example, an event marker entered on the horizontal
display disappears from that display when it goes out of the current range. However, when
entered on the video plotter display it remains on the video plotter display for a much longer
time when a long range scale is used. This can be useful when you want to return to the
location denoted with an event marker. Like with the horizontal display you can inscribed
five event markers on the video plotter display.
To display track on the horizontal display, the tilt angle must be less than 75 degrees.
You may switch control between the horizontal display and the video plotter display with the
MAIN/SUB key. The message MAIN WINDOW CONTROLLABLE or SUB WINDOW
CONTROLLABLE appears with each pressing of the key. A red rectangle circumscribes the
sub window when it is chosen. With the video plotter display selected you may change its

Displaying weak echoes clearly
Echoes from targets (such as the bottom or a fish) return to the transducer in order of the
distance to them, and when their intensities are compared at the transducer face, those
from nearer targets are generally stronger when their reflecting properties are nearly equal.
The sonar operator will be quite inconvenienced if these echoes are directly displayed on
the screen, since he won’t be able to judge the actual size of the target from the size of
echoes displayed on the screen. To overcome this inconvenience, use the TVG function. It
compensates for propagation loss of sound in water: amplification of echoes on short range
is suppressed and gradually increased as range increases, so that similar targets are
displayed in similar intensities irrespective of the ranges to them.
The TVG also functions to suppress unwanted echoes and noise which appears in a certain
range area on the screen.

Interpreting the Vertical Scan Display
This section provides information necessary for interpreting the vertical scan display.
3.14.1
How the vertical scan mode picture is painted
The sounding beam is emitted and the information (target echoes) obtained by the beam
appears in the corresponding sector as it appears on the sonar mode. The difference is that
the training is performed only in vertical direction. It forms a sounding area of a half-circle
(like a slice of watermelon) to observe a vertical section of underwater conditions.
The bearing of the vertical sounding beam can be chosen manually or automatically.

Suppressing interference and noise
You may encounter occasional noise or intermittent interference on the display. This is
mostly caused by electrical equipment, engine, propeller noise from own ship, or noise from
other sonars being operated nearby. If interference appears, turn on the interference
rejector in the COM1 menu to suppress it. Note that the interference rejector cannot be
turned on/off independently for each frequency in case of the dual-frequency display.

4.11.1
Echo sounder menu description
TVG LEVEL: Compensates for propagation loss of sound in water. See paragraph 4.10.1.
Default setting is 4.0.
TVG DISTANCE: As above. Default setting is 4.0.
RES. COLOR: Sets transfer characteristics of input signal level versus display echo level.
Echo strength is emphasized in order of CUBE, SQUARE, LINEAR, LOG. You can see the
characteristics of each by watching the color bar as you change the setting. The default
setting is LOG.
LOG:
Displays weak to strong echoes in their respective levels. This setting is suitable for
general use.
LINEAR: Downplays the weak echoes when compared with LOG. Effective for suppressing
weak echoes such as plankton.
SQUARE: Strong echoes are emphasized more than in LINEAR.
CUBE:
Strong echoes are emphasized even more than in SQUARE.
CLUTTER: Low intensity echoes, often caused by sediments in water, are painted on the
screen as a large number of random dots. The higher the number (setting) the weaker the
echoes which are erased.
A- SCOPE: Turns the A-scope display on/off. Default setting is OFF. See paragraph 4.10.2.

5. MENU OPERATION
5.1.1
COM1 menu description
TX POWER: Chooses transmitter output power to maximum or minimum. The default
setting is "maximum." For further details see paragraph 2.12.1.
PULSELENGTH: Chooses pulselength to short or long (default setting). For details see
paragraph 2.12.2.
TX RATE: The Tx rate may be set between 1-10 (default setting: 10) in the case of the
internal transmitter, or an external synchronous signal may be used. The higher the number
the greater the number of transmissions. For operation in shallow waters, choose the Tx
rate which displays the second reflection from the bottom between the sea surface and
bottom. For use of an external video sounder or sonar, choose EXT.
INT REJECT: Turns the interference rejector on (high freq, low freq or both low and high
appears at the top of the screen. Note
freq) or off (default setting). When turned on
that the interference rejector cannot be turned on/off independently for each frequency in
case of the dual-frequency display. For further details about interference rejection, see
paragraph 2.12.5 (horizontal display) and 3.12.2 (vertical scan display).
AGC: Automatically lowers sensitivity against strong echoes such as those from the bottom
and large fish schools to emphasize weak echoes such as those from fish close to the
bottom. The default setting is OFF.
AUDIO LEVEL: Adjusts the audio level (0-10) of the external loudspeaker (option).
Sometimes you may be preoccupied with other tasks and unable to concentrate on
watching the sonar picture. In such cases it would be a good choice to use the audio
function. This function enables you to monitor echoes from fish schools and seabed through
the built-in speaker. After you’ve become accustomed to monitoring fish aurally, you should
be able to detect a fish school from a range longer than you can detect it on the screen. In
addition you may judge whether the fish school is approaching or going away; the tone
becomes higher when the school is approaching and lowers when the school is going away.
Note: If a dual-frequency display is active, the frequency sound from the left-side display*
(for the dual-frequency vertical scan display the top display) is output.

OFF, 1/2 and 1/1, in ascending order of strength. If the setting is too strong, noise will result.
Watch the display while changing this setting.
If noise exists on short range or if the echo strength of like size fish from long and short
ranges is different use the TVG feature. For further details, see 2.12.3, 3.12.1 and 4.10.1.
UNIT: Chooses unit of depth measurement: meters (default setting), feet, fathoms,
passi/braza, Hiro.
TEMP: Chooses unit of water temperature measurement: °C (default setting), °F.

heading and latitude and longitude data from external equipment. Default setting is OFF.
CUSTOM KEY: Chooses function of custom mode keys: preset (default setting) or short-cut.
For details see paragraph 5.2.
ETA MARK: A vector line extends from the own ship marker in direction of ship’s bow on
the horizontal mode display. The tip of the line shows the estimated time of arrival after the
selected ETA time elapses, using the current ship’s speed. ETA is calculated every second
considering tilt and detection range. This function requires speed input.

MAINTENANCE,
TROUBLESHOOTING
This chapter provides information necessary for keeping the equipment in good working
order.
WARNING
ELECTRICAL SHOCK HAZARD
Do not open the equipment.
Only qualified personnel
should work inside the
equipment.
6.1
Preventive Maintenance
Check the following points monthly.
• Check all cables. If damaged, replace.
• Check connectors at rear of each unit. Clean if necessary.
• Check earth of each unit. Clean if necessary.
• Check voltage of ship’s mains to be sure it is within the equipment’s power rating.
6.2
Cleaning the Equipment
Dust or dirt can be removed from the equipment with a soft, dry cloth. Do not use chemical
cleaners to clean the equipment – they can remove paint and markings. The LCD will, in
time, accumulate a coating of dust which tends to dim the picture. Wipe LCD lightly with soft
cloth to remove dust.

6.3.1
Hull Unit Maintenance
Lubrication
Grease the raise/lower screw shaft once a year. Also, grease the raise/lower main shaft
(upper part of the grease cotton retainer) twice a year. These parts can be accessed by
removing the raise/lower drive assembly cover.
6.3.2
Manually raising, lowering transducer
WARNING
Turn off the power at the ship's mains
switchboard before conducting the
procedure below.
Rotating motor can cause bodily injury.
1. Turn off the breaker on the hull unit.
2. Turn nut with 19 mm ratchet wrench.
3. Check that the transducer raises and lowers smoothly, from the upper to the lower limit
positions. If the transducer cannot be raised smoothly, do not use excessive force; the
shaft may bend, causing damage to other components.
4. Check soundome and tank. Remove marine life with fine sandpaper or piece of wood.
Attach ratchet
wrench here.
Hull unit
6-2
6. MAINTENANCE, TROUBLESHOOTING
6.4
Transducer Maintenance
When the ship is dry-docked remove marine growth from the transducer with fine
sandpaper or a piece of wood. Coat the transducer face with anti-fouling paint (Chugoku
MarineStar 20 Red or the equivalent)
NOTICE
Do not paint the transducer face.
Loss of sensitivity will result.
Do not use plastic solvents to clean the
transducer.
They can damage the transducer.
6.5
Fuse Replacement
The fuse in the hull and transceiver units protect them from overvoltage, equipment fault
and reverse polarity of the ship’s mains. If the power cannot be applied first check that the
power cable between the transceiver unit and the monitor unit is firmly connected. If the
power still cannot be applied, the fuse in the transceiver unit may have blown. Have a
suitably qualified technician check the fuse.

6.6
Troubleshooting
The table below provides common symptoms of equipment troubles and the means to
rectify them.
Symptom
Cannot turn on the
power.
Check, Remedy
• Check cable between transceiver unit and monitor unit.
• Check ship’s mains.
• Have a suitably qualified technician check the fuse in the
transceiver unit.
Bottom echo
becomes irregular.
• Rough seas. Distance to the bottom changes due to rolling and
pitching.
• Long range selected. Transmission period is longer so ship’s
pitching and rolling are apt to affect detection of echo.
Weak echo
• Output power set to minimum. Set to maximum, on the COM1
menu.
• Excessive TVG. Readjust TVG on the appropriate menu (HORZ,
VERT, ES). Note that readjustment of TVG is necessary when gain
is adjusted.
Somewhat strange
color
• Brilliance setting too low. Increase brightness with BRILL key
(supplied monitor) or brilliance control on commercial monitor.
Picture contains
noise.
• Equipment not grounded properly. Check equipment ground.
• Power cable is too close to the signal cable. Relocate power cable
or signal cable.
• Debris may be on sea surface. Reject unwanted noise with the
interference rejector on the COM1 menu.
Picture does not
change when tilt
angle is changed.
(Bottom is not
displayed in vertical
scan picture when
bottom is flat.)
• Problem in tilt mechanism or control line. Contact a FURUNO agent
or dealer for advice.
