Usage Hints
When installing this set, be sure to connect
the grounding wire to the grounding terminal
of the set. Otherwise, an electric shock can
result when a failure or leakage occurred on
the set.
Do not damage, break or modify the power
cord.
Placing a heavy load, heating, pulling or for-
cibly bending the cord can damage it result-
ing in a fire or an electric shock.
Do not use this set at a voltage other than the
supply voltage stated on the set. Otherwise,
a fire, an electric shock or system failure can
result.
Do not touch inside the set with wet hands.
When your hands are wet, don’t try to con-
nect or disconnect the power cord or touch
the switches. Otherwise, an electric shock
can result.

4
When cleaning the surface, do not use any
organic solvent such as thinner or benzene.
Otherwise, the painting on the surface may be
damaged.
For cleaning the surface, remove the dust,
then wipe with clean dry cloth.
Do not try to make transmission when the
transducer is not connected, otherwise, the
transducer may fail.
Do not try to make transmission when the
transducer is not in water. Otherwise, the
transducer or transmitter may fail.
Do not bring the set in a cooled state suddenly
into a warm room.
A high voltage may leak due to dew condensa
-
tion resulting in a failure. In this case, use
the set after leaving it alone for 30 minutes.
When removing the power cord, be sure to re-
move the power cord terminal correctly.
Pulling the power cord can damage it resulting
in a fire or an electric shock.

2 Installation
Do not install the set in a place that exposes the CRT to direct sun
for a long time or a place whose environmental temperature can
reach 55 degree Centigrade or above. Otherwise, fire hazards or
system failure can result from such operating environment.
Do not install the set on an unstable place such as shaky or in-
clined bench. Otherwise, personal injuries can result from the
fallen or collapse set.
Environment of the set must be free of magnetism field. Failure to
observe this precaution may disturb the screen display colors of
water depths or of alarms, thus causing accidents.
Do not close the ventilation port of the set. Otherwise, fire haz-
ards or system failure can result from the heated set.
Reasonable care must be exercised for the routing of piezoelectric
transducer, power cable and grounding cable. Otherwise, the
echo sounder can adversely effect other equipment or vice versa.
When the echo sounder installation is complete, turn on power for
all other equipment to make sure that they are free of troubles.

2.1 Mounting of Echo Sounder
(1) Mounting location
1. The transducer cable tends to pick up generate noise, thus the echo sounder must
be installed in a location that can prevent interference between the cable and a co-
axial cable on a radio equipment.
2. The echo sounder must not be installed near a DSB or amateur radio equipment.

(2) Mounting procedure
1. Loosen two main body fixing bolts situated at lower front side of the main body, then
remove the mounting plate.
2. Drill four tapping screw holes (φ4 mm) in the main body mounting location.
3. Using the tapping screws attached to the main body, fix the mounting plate to the
desk.
4. Using the two bolts already being removed (in the step 1 above), fix the main body
to the mounting plate.

2.3 Connecting the Power Supply and Transducer Connectors
(1) Connecting the Power Cables
1. Use 7ZCNA0827A(CFQ-8827) for the power cable.
2. Connect the power cables as indicated below:
3. When the installation requires to extend the power cable, the cable used must be
DPYC-2.5or above so that voltage on the connector when conducted may not go
10.2V or less.
4. At powering on, 8A current (10.2V) is conducted to the JFV-700HP for two sec-
onds. Current capacity of a circuit breaker, if any, must be suitable for the above
current.
5. If you connect the power cable to the power terminal used on the radio equipment,
noise can be generated on the equipment.
(2) Power Cable Connecting Procedure for AC specification
1. Connect NBA-3263 rectifier to the AC power supply (100/110/220V), then connect
the power cable to the rectifier.
(3) Power Cable Wiring Procedure
1. Don't try to bundle the radio equipment coaxial cable with the echo sounder power
cable. Such practice can generate noise on the radio equipment.
(4) Transducer Cable Connecting Procedure
1. Connectors are attached to the transducer. Connect the cables to the connectors
as indicated below, then solder them to the connectors.

(5) Transducer Cable Wiring Procedure
1. Don't try to bundle the transducer cable with other cables. When this cable is
routed along with another cable, 50 cm minimum space must be provided between
the them.
2. The cable on the echo sounder transducer tends to pick up or generate noise, thus
it must not be bundled with the coaxial cable on the radio equipment.
3. It is recommended to route the transducer cable through iron pipe.

For DC specs., connect the 7ZCBS0827A (CFQ-8827) to the inboard power supply.
For AC specs., connect the 7ZCBS0827A (CFQ-8827) to the NBA-3263 rectifier.
Use DPYCY-2.0 (or higher in ratings) as an extension power cable.
