SAFETY INSTRUCTIONS
iii
CAUTION
Check the zinc plate (anticorrosion
measure) regularly for corrosion and
replace it when the ship is drydocked.
Corrosion may occur. As a result the
transducer may fall out, allowing water to
leak inside the vessel.
Do not use the equipment for other than
its intended purpose.
Damage to the equipment or bodily
injury may result if the equipment is
misused.
Do not transmit with the transducer out
of water, when drydocked, etc.
The transducer may become damaged.
Turn off the power at the switchboard
immediately whenever you feel the
equipment is abnormal.
Turn off the equipment at the switchboard
if it becomes warm or is making strange
noises. Contact your dealer at your earliest
convenience.
A warning label is attached to the
transceiver and monitor units. Do not
remove the labels. If a label is missing
or damaged, contact a FURUNO agent or
dealer about replacement.
WARNING
To avoid electrical shock, do not
remove cover. No user-serviceable
parts inside.

FOREWORD
A Word to the Owner of the CI-68
Congratulations on your choice of the FURUNO CI-68 Doppler Sonar Current Indicator. We are
confident you will see why FURUNO has become synonymous with quality and reliability.
Since 1948, FURUNO Electric Company has enjoyed an enviable reputation for innovative and
dependable marine electronics equipment. This dedication to excellence is furthered by our ex-
tensive global network of agents and dealers.
Your current indicator 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 op-
eration and maintenance.
Thank you for considering and purchasing FURUNO equipment.
Features
• With heading data from a gyrocompass, satellite compass, etc., the absolute movements of tide
measuring layers is displayed, in colors.
• When ground (bottom) reference is not available acoustically; namely, ship is in deep water, this
equipment provides absolute movements of measuring layers by receiving position (or speed)
data from a GPS navigator and heading data from a gyrocompass or satellite compass.
• Single-mold transducer plus compact monitor unit, control unit, transceiver unit and junction box
(option) permit installation on small vessels.
• Data is displayed on a bright, non-fading 10.4 inch TFT LCD. Background color is selectable
from three colors.
• Commercially available monitor may be used in lieu of the LCD monitor.
• Six display modes to discern tide movement from a variety of angles.
• Logical keyboard layout and menu structure for intuitive operation. Function key provides short-
cut menu operation.
• Triple-beam system for automatic error compensation against pitching and rolling.
• Echo level continuously displayed on the screen, for monitoring signal conditions on three
sounding beams.
• Bottom echo can be found using external depth data. Further, the bottom echo can be acquired
manually by monitoring the echo level display. This is useful when in deep seas, air bubbles
block reception of the bottom echo, or a thick layer of plankton or a large fish school is mistak-
enly tracked as the bottom echo.
• Various alarms: tide, tide differential, speed, trip, etc. Audible and visual alerts are released if
alarm condition is violated.
• Graph display shows past current data.
• Water temperature graph helps locate current rip. (Temperature sensor required.)

DISPLAY EXAMPLE
Tide vector display
Solid line: The speed and direction of the tide
• Tide vector for Layer 1 (LYR1) : Yellow
• Tide vector for Layer 2 (LYR2) : Purple
• Tide vector for Layer 3 (LYR3) : Blue
• Tide vector for Layer 4 (LYR4) : Green
