COLOR Fish Finder FF50
Before You Begin
Thank you for purchasing our JRC color LCD Fish Finder FF50.
This unit displays fish schools in color on a bright TFT LCD screen.
•This unit is for detecting schools of fish. Before attempting to
operate it, read this instruction manual thoroughly to correctly and
safely operate this unit in accordance with the warning instructions
and operation procedures in this manual.
•Storing this instruction manual carefully for future reference is highly
recommended. In the event that you have an operational problem or
malfunction, this manual will provide useful instructions.
•This unit is an aid to navigation. It's accuracy can be afected by
many factors including equipment failure or defects, environmental
conditions, and improper handling or use. It is the user’s responsibil-
ity to exercise common prudence and navigational judgement. This
unit should not be relied on as a substitute for such prudence and
judgement.
The LCD uses 224,000 or more TFTs (Thin Film Transistor).
If some pixels on the screen are not clear, the color is different, or the
screen is brighter than usual, it is not because of defect, instead it is
because of inherent characteristics of the TFT display technology.

Usage Hints
Do not remove the cover of the
unit. Doing so may cause an
electric shock
by high voltage
from within
the product’s
enclosure.
Do not touch the radiator fin of the
unit. Doing so
may cause a burn
by high
temperature.
Do not try to disassemble or
modify the unit.
Doing so may
cause a fire,
electric shock
or malfunction.
Do not place objects
containing liquid or
metal fragments on
top of the unit,
which might be
spilled or dropped
into the unit.
Doing so may cause a
fire, electric shock or malfunction.
WARNING
Operate the unit only
on 12 VDC to 24 VDC.
Not doing so may
cause fire or
electrical shock.
Do not (dis)connect the power
cable(from) to the main unit with
wet hands, as
doing so
may cause
electrical
shock.
In the event that you spill or drop
any liquids or metals etc., turn off
the main unit, unplug the power
supply terminal, and contact our
company, branch, or local office.
Continuing
operation as
is may cause
a fire, electric
shock or
malfunction.
In the event that smoking or burning
odors are detected, immediately
terminate operation of the unit and
contact your dealer. Continuing
operation as is may cause
a fire or
electrical
shock.
Never
attempt
to service
the interior
of the unit.

When disconnecting
the power cable,
be sure to grasp
it by the plug.
Never pull on the
connecting cord
itself, as doing so
increases the risk
of malfunction.
Do not drop the unit
into water. When
disconnecting the
connector on the
back side,
be sure it does
not get wet, as
doing so increases
risk of electrical shock or
malfunction.
Do not use or
install the unit
in a place where
the LCD is subject
to direct
sunlight, or in
a location near
heat sources
where the temperature
is 50°C or more.
Doing so may cause a malfunction
or defect.
Do not turn on the unit immediately
after moving it from a cold place to a
warm one. Let the unit stand for
around 30 minutes before turn on,
until the inside temperature of the
unit reaches the same level as that of
the room it was moved to.
Not doing so increases risk of
malfunction.
Do not try to turn
on the main unit while
the transducer is
disconnected or
out of the water.
Doing so may cause
an electrical shock
or malfunction.
Be sure to connect a cable to the
grounding terminal when installing.
Not doing so may cause an electric
shock or
excessive
noise from/
to other
equipment.
Do not use any type
of organic solvent
such as thinner
or benzine
when
cleaning the
surface of
the cabinet.
Doing so may damage the coating or
the finish of the unit’s surface.
Remove any dust and clean the unit’s
surface with a soft dry cloth.

EMC Installation & Service Guidelines
IMPORTANT NOTE
All JRC equipment and accessories are designed to the highest industry
standards for use in a marine environment. Their design and manufacture
conforms to the appropriate Electro Magnetic Compatibility (EMC) standards,
but good installation is required to ensure that performance is not compromised.
Although every effort has been taken to ensure that the equipment will perform
under all conditions, it is important to understand what factors could affect
operation of the product. Complete installation instructions are provided in
SECTION 3 of this manual. Some preliminary suggestions are made below.
Installation
To avoid the risk of operating problems, all JRC equipment and cables
connected to it should be:
•At least 1m (3 feet) from any equipment transmitting or cables carrying radio
signals e.g. VHF radios, cables and antennas. In the case of SSB radios the
distance should be increased to 2m (7 ft).
•More than 2 m (7 ft) from the path of a radar beam. A radar beam can nor-
mally assume to spread 20 degrees above and below the radiating element.
•The equipment should be supplied from a different battery than the one used
for engine start. Voltage drops below 10V in the power supply to our products
can cause the equipment to reset. This will not damage the equipment, but will
cause some loss of information and this can also change the operating mode.
•Genuine JRC Cables should be used at all times. Cutting and rejoining these
cables can compromise EMC performance and should therefore be avoided
unless doing so is suggested in the installation manual.
Check Before Going to Sea
•Always check the installation before going to sea to make sure that it is not
affected by radio transmissions, engine starting, low battery voltage, or other
problems.
•In some, installations, it may not be possible to prevent the equipment from
being affected by external influences. In general this will not damage the
equipment but it can lead to it resetting, or momentarily may result in faulty
operation. This can then be avoided by turning off the FF50 prior to starting
the boat engines for instance.
6
Servicing and Safety
•JRC equipment should be serviced only by authorized JRC service engineers.
They will ensure that service procedures and replacement parts used will not
affect performance. There are no user serviceable parts in any JRC product .
•Some products generate high voltages, and so never handle the cables /connec-
tors when power is being supplied to the equipment.
•Always report any EMC related problem to your nearest JRC dealer. We will
use any such information to improve our quality standards.
Suppression Ferrites
The following illustration shows the range of suppression ferrites fitted to
JRC equipment.
Notes for Suppression Ferrite Installation
Connections to other equipment
If your JRC equipment is going to be connected to other equipment using a
cable not supplied by JRC, a suppression ferrite MUST always be fitted to the
cable close to the JRC unit.
