SAFETY INSTRUCTIONS
WARNING
Immediately turn off the power at the
switchboard if water leaks into the
equipment or something is dropped in
the equipment.
Continued use of the equipment can cause
fire or electrical shock. Contact a FURUNO
agent for service.
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 operate the equipment with wet
hands.
Electrical shock can result.
ELECTRICAL SHOCK HAZARD
Do not open the equipment.
Only qualified personnel
should work inside the
equipment.
DANGER
Never touch the SSB antenna, antenna
coupler or lead-in insulator when the
SSB radiotelephone is transmitting.
High voltage which will cause death or
serious injury is present at the locations
shown in the illustration below when the
SSB radiotelephone is transmitting.
Antenna
Coupler
Antenna Wire
(High Voltage)
Indoor Antenna
Wire
Lead-in
Insulator
(High
Voltage)
Use the proper fuse.
Use of the wrong fuse can cause serious
damage to the equipment and void the
warranty.
CAUTION

iii
Do not operate the [DISTRESS] button
except in case of a life-endangering
situation on your vessel.
If the distress alert is accidentally
transmitted, contact the nearest coast
station and inform them of the accidental
transmission as follows:
a) Ship's name
b) Ship's call sign and DSC number
c) Position at time of transmission
d) Time of transmission
This equipment is intended for maritime
use. Do not use it in other applications.
A warning label is attached to the
transceiver unit and a danger label is
attached to the antenna coupler.
Do not remove the labels.
If a label is missing or illegible,
contact a FURUNO agent or dealer
about replacement.
WARNING
To avoid electrical shock, do not
remove cover. No user-serviceable
parts inside.

1.2 Turning the Power On/Off
Press the [POWER] switch at the right-hand side of the control unit to power the system.
Press it again to turn the system off. In the dual control unit system, the control unit
connected to the CONTROLLER 1 port on the transceiver unit has priority and it controls
the power for both the No.1 and No. 2 control units. The power switch of the No. 2 control
unit powers on/off the No. 2 control unit only.
Note: Turn on ship’s mains five minutes before turning on this equipment.
