FOREWORD
A Word to the Owner of the FURUNO FSV-84
Congratulations on your choice of the FURUNO FSV-84 Color Scanning Sonar.
We are confident you will see why the FURUNO name has become synonymous
with quality and reliability.
For over 50 years FURUNO Electric Company has enjoyed an enviable
reputation for quality 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 operated and maintained properly. Please carefully read and follow the
recommended procedures for operation and maintenance.
Thank you for considering and purchasing FURUNO equipment.
Features
The FSV-84 is a full-circle, multibeam electronic color scanning sonar which
detects and displays fish schools on a 21-inch non-glare, high-resolution color
monitor. (System also available without monitor.)
The main features of the FSV-84 are
• Cylindrical + sphere transducer provides 90 degrees vertical detection.
• Vivid 32-color echo strength dependent display for improved recognition of
bottom, fish school concentration, distribution and volume.
• Fish schools can be searched from horizontal (range direction), vertical (depth
direction) with vertical and half-circle features.
• Function keys for direct access to desired menu item.
• User programs for one-touch setup of equipment.
• Menu-driven operation.
• Fish histogram shows signal strength distribution of echo within estimate
mark.
• Various marks and alphanumeric fishing and navigation information for
intuitive operation.
• Memory cards for storage and replay of picture and settings.

FOREWORD
xii
• Audio function allows monitoring of echoes along user-selected area through
built-in loudspeaker.
• Fish mark estimates fish speed.
• Fish estimate feature compares volume of two fish schools.
• Target lock automatically tracks fish school.
• Net course mark shows probable drift of net against tide.

1.2 Turning the Power On/Off
1.2.1 Turning the power on
Press the POWER ON (|) switch.A beep sounds, the lamp above the switch
lights, and the last-used mode is presented.
1.2.2 Turning the power off
1. First retract the transducer with the [ ] key. The lamp above the switch blinks
while the transducer is being raised and lights steadily when it is fully raised.
Note: While raising the transducer, the ship speed must be no more than 15
kts to prevent damage to the transducer and hull unit.
2. Press the POWER OFF ( ) switch for more than one second, after the [ ]
key lights steadily.
Note: The transducer is automatically retracted into the tank if the POWER
OFF ( ) switch is pressed before retracting the transducer. However,
for safety purposes, make it a habit to retract the transducer before
turning off the power.

1.3 Lowering, Raising the Transducer
CAUTION
Maximum speed while the transducer is
projected and being raised or lowered
is as below, to prevent damage to the
transducer.
Projected Raising/
Lowering
800 mm stroke Max. 18 kt Max. 15 kt
1100 mm stroke Max. 18 kt Max. 15 kt
1.3.1 Lowering the transducer
With the boat at the fishing ground, press the [ ] or [ ] key. The lamp above the
key pressed blinks during lowering and lights when the transducer is completely
lowered to selected protrusion distance. It takes about 21 seconds for full
protrusion in case of 800 mm stroke and 28 seconds in case of 1100 mm stroke.
In normal use fully lower the transducer. If the transducer becomes entangled in
the net for some reason, partially raise the transducer with the [ ] key. This
raises the transducer by 400 mm.
1.3.2 Raising the transducer
Press the [ ]key to raise the transducer. The lamp above the switch blinks while
the transducer is being raised and lights steadily when it is fully raised.
1.4 Screen Brilliance
The [BRILLIANCE] control adjusts screen brilliance.Adjust it to suit lighting
conditions.
Note: The brilliance of an external monitor cannot be adjusted with the
[BRILLIANCE] control. Use the associated control on the monitor.
