SAFETY INSTRUCTIONS
Safety Instructions for the Operator
WARNING
Do not open the equipment.
There are no uer-serviceable parts inside.
Do not disassemble or modify the
equipment.
Fire, electrical shock or serious injury can
result.
Immediately turn off the power at the
switchboard if the equipment is emitting
smoke or fire.
Continued use of the equipment can cause
fire or electrical shock. Contact a FURUNO
agent for service.
Do not maneuver the vessel based
on the depth indication alone.
Grounding may result.
Use the proper fuse.
Fuse rating is shown on the equipment.
Use of a wrong fuse can result in damage
to the equipment.
Do no turn on the equipment with the
transducer out of water.
The transducer may be damaged.
The picture is not refreshed when
picture advancement is stopped.
Maneuvering the vessel in this condition
may result in a dangerous situation.
Use the proper gain setting.
Incorrect gain may produce wrong depth
indication, possibly resulting in a dangerous
situation. See "Adjusting the gain" on page
7 for details.
CAUTION
WARNING
To avoid electrical shock, do not
remove cover. No user-serviceable
parts inside.

Safety Instructions for the Installer
WARNING
Turn off the power at the switchboard
before beginning the installation.
Fire or electrical shock can result if the
power is left on.
Be sure no water leaks in at the trans-
ducer or sensor mounting location.
Water leakage can sink the vessel. Also
confirm that the transducer and sensor will
not loosen by ship's vibration. The installer
of the equipment is solely responsible for
the proper installation of the equipment.
FURUNO will assume no responsibility for
any damage associated with improper
installation.
Use the specified power cable.
Use of other power cable may result in
fire.
CAUTION
Do not install the equipment where
air bubbles and noise are present.
Performance will be affected.
The following are guidelines for
handling of the transducer cable.
- Do not locate near oils and fuels.
- Locate it in a safe place.
- Do no paint the cable.
The sheath of the cable is made of
chloroprene rubber (or polychloride
vinyl). For this reason do not paint
the cable.
Observe the following compass safe
distances to prevent interference to a

FOREWORD
A Word to LS-6100
Owners
Congratulations on your choice of the

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 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 operated and maintained properly.

Features
The FURUNO LS-6100 is a dual frequency
(50 kHz, 200 kHz) monochrome LCD echo
sounder. Comprised of a display unit and a
transducer, the LS-6100 displays
underwater conditions on a bright 6-inch
monochrome LCD.
The main features of the LS-6100 are
• Compact design permits installation
where space is limited.
• Bright 6-inch monochrome LCD gives
excellent readability even in broad
daylight.
• Wide variety of display modes: single
frequency, dual frequency, bottom-lock,
marker-zoom, bottom-zoom, and nav
data.
• Automatic function permits unattended
adjustment of range and gain. The range
scale and gain automatically change to
display the bottom in the darkest gray
tone on the lower half of the screen.
• User-programmable nav data displays
provide analog and digital nav data.
• Alarms: Bottom, Fish (bottom-lock and
normal), Speed, Water Temperature and
Arrival. (Speed and arrival alarms require
appropriate sensor; water temperature
alarm requires water temperature data.)
• A-scope display helps discern echo
amplitude.
• White line feature helps discriminate fish
lying near the bottom.
• Destination waypoint feature provides
range, bearing, and time-to-go to
destination waypoint.
• Waterproof construction permits
installation on open bridge.

Single frequency display
50 kHz
The sounder uses ultrasonic signals to
detect bottom conditions. The lower the
frequency of the signal, the wider the
detection area. Therefore, the 50 kHz
frequency is useful for general detection
and judging bottom condition.
200 kHz
The higher the frequency of the ultrasonic
signal the better the resolution. For this
reason the 200 kHz frequency is ideal for
detailed observation of fish schools.
