Chapter 1 INTRODUCTION
1.1 System Diagram
The figure below shows the system diagram for the RC-1500-1T. Equipment are controlled
using FURUNO’s own radio interface system called MIF (see note below).
The type and number of the component differ from set to set.
Note: MIF is a handshaking type signal exchange system developed by FURUNO for remote
control of our radio equipment. In the RC-1500-1T, for example, the DSC-60 can automatically
set the frequency on the FURUNO SSB Radiotelephone.

1.2 Equipment Description
Keep the all equipment powered while the vessel is underway by regulations.
FURUNO SSB Radiotelephone
For ship-ship and ship-station radio communications in the MF/HF band. The main communi-
cations modes used are;
• Voice communications (J3E/H3E) via the handset
• DSC communications (Telex) by the DSC-60
• Telex communications by the DP-6
DSC-60 MF/HF DSC Terminal
The DSC-60 has many functions. Below are its main functions.
• Distress alert: Transmit the distress alert via the FURUNO SSB Radiotelephone.
• Watches DSC distress and safety frequencies. The DSC-60 receives distress alert from ves-
sel in distress and all ships call (safety and urgent call) from ship or coast station.
• All Ships Call: For urgent situation on own ship (for example, request for medical assis-
tance).
• Individual Call: Place a call to a specific ship or coast station.
NBDP Terminal
The DP-6 provides Telex communications with coast stations over the MF/HF band via the
FURUNO SSB Radiotelephone. Furthermore, it can receive MSI (Maritime Safety Informa-
tion) messages via the FURUNO SSB Radiotelephone (Scan reception).
Note: NBDP is not included in the dual Inmarsat C type radio rack console.
Inmarsat C Mobile Earth Station
Provides distress and general Telex communications for mobile and fixed terrestrial subscrib-
ers in the Inmarsat C communications network.Telex messages are processed by what is known
as store-and-forwardTelex.ATelex message transmitted by you arrives at a coast station where
it is stored temporarily and then delivered to the subscriber specified (No full duplex communi-
cations possible.)
AC/DC Radio Switch Box
TheAC/DC Radio Switch Box consists of a battery charger and two rectifiers (PR-850AR and
PR-300) which can accept both AC and DC powers. In the event of main AC power failure,
auxiliary power (battery) provides power to the equipment, for the amount of time stipulated by
radio regulations.

1 –4
1.3 Mutual Operation of Equipment
As noted earlier, the equipment in this radio console are interfaced by FURUNO's MIF radio
interface. For example, to transmit a message over the DSC-60 or DP-6, the Tx and Rx frequen-
cies and class of emission are automatically set on the FURUNO SSB Radiotelephone and then
the message is transmitted.
Two printers are supplied and one is dedicated to the Inmarsat C. The other printer is for both
the DSC-60 and DP-6. If the DP-6 is used (message transmission or reception), this printer is
automatically connected to the DP-6 to print out the data. When the printer selector switch in
the console is set to the “AUTO” position, it automatically connects one of those equipment to
the printer on a first-come-first-served basis. For example, if the DSC-60 is used (message
transmission or reception), the printer selector switch automatically connects the printer to the
DSC-60 and disconnects itself from other equipment.
Connection between DSC-60 and DP-6
Suppose you transmitted a call over the DSC-60 and want to communicate with the receiving
station by the DP-6 instead of FURUNO SSB Radiotelephone. If the DSC-60 and DP-6 were
not connected you would have to set the several data such as working frequency, communica-
tion mode, etc. manually on the DP-6. Because they are connected by the remote function,
however, the data mentioned above are automatically set on the DP-6 via the DSC-60.

Battery charging
Before operating the radio, check the battery voltage on the meter provided on the AC/DC
Radio Switch Box. The battery voltage is maintained between 24VDC and 27.5VDC when the
BATTERY CHARGER switch is in the AUTO position. Note that the OFF position of the
BATTERY CHARGER switch may allow the voltage to drop below 24 VDC. In this case,
charge the battery as follows:
1. Set the BATTERYCHARGER switch for MANUAL. Watch the charging current at theAC/
DC Radio Switch Box. (For a 200AH battery, the charging current will be around 20Aat the
start, and will be reduced gradually as charging proceeds.) For maintenance free
battery, set the BATTERY CHARGER switch for AUTO.
2. Turn the BATTERY CHARGER switch off or set it to AUTO when the charging current
falls below 2A.
Note: If the AC power has failed, the radio battery automatically supplies power to the radio
equipment regardless of BATTERYCHARGER switch position. The battery will not discharge
as long as the AC power is alive.
Care of the lead-acid battery
The lead-acid battery powers distress-related communications equipment when the ship’s main
power and emergency power fail, to enable communications in the event of distress. Therefore,
follow the points mentioned below to keep the battery in good working order.
Keep sparks and lit smoking materials
away from the lead-acid battery. Make sure
the battery room is well ventilated.
The battery emits hydrogen gas which can
cause explosion.
The electrolyte in the lead-acid battery
contains sulfuric acid which can be harm-
ful, particularly to the eyes.
If sulfuric acid contacts eyes, skin or clothing,
flush directly with water. For eyes, contact a
physician. Loss of eyesight can result.
The temperature of the electrolyte in the
lead-acid battery should not exceed 45°C.
The electrolyte can cause explosion if it
becomes too hot.

1. Confirming charging
Confirm that the BATTERY CHARGER switch on the control panel is set for AUTO. Further,
confirm that the battery voltage meter on theAC/DC Radio Switch Box reads between 24 V and
27.5 VDC.
2. Checking specific gravity of electrolyte
The specific gravity of electrolyte is normal if it is 1.240 ±0.010 (at 20°C).
3. Water supply
The electrolyte level can be seen on the battery. When the electrolyte falls below the highest
graduation on the scale, fill to highest graduation with distilled water. Do not use diluted sulfu-
ric acid or ordinary tap water—they will shorten battery life.
4. Cleaning
The battery and the area around it should always be clean and dry. Clean the battery case with
a water-moistened cloth. Do not use chemical cleaners to clean the battery; they may crack the
case. Kerosene may be used.
5. Environmental conditions
• Keep the battery out of direct sunlight.
• Coat the nuts and bolts which secure the battery contacts with anticorrosive paint for the
lead-acid battery. Check yearly that bolts are securely fastened. Tighten nuts and bolts if
necessary.
2.2 Maintenance
1. Cleaning display screens
Dust or dirt on the display screens of equipment may be removed with a soft cloth. Do not use
chemical cleaners—they may remove paint and markings.
2. Cleaning floppy disk drives
The heads in the floppy disk drive of the DP-6 and FELCOM 12 should be cleaned regularly to
prevent damage to floppy disks. Use a floppy disk cleaning kit. (FURUNO can supply a floppy
disk cleaning kit. It is type MCD-2, code no. 000-116-420.)
Procedure
1. Insert a floppy disk cleaning kit in the drive.
2. Execute “Format” operation (in the F1 menu). The access lamp on the drive lights.
3. Wait until the access lamp goes off. Remove the disk. (Error message for formatting appears
