Chapter 1 INTRODUCTION 1.1 Operational Overview The RC-1800F/1800T radio rack console conforms to the IMO regulations for GMDSS radio equipment. It contains an SSB radiotelephone, DSC terminal, NBDP terminal and Inmarsat C mobile earth station. The RC-1800F is operated with the control panel and the dimmer knob. You can monitor the AC mains source by the Lamp. Power can be checked with the power meter. The RC-1800T is operated with the control panel and the dimmer knob (option).
1.2 System Diagram The figure below shows the system diagram for the RC-1800F/1800T. The RC-1800 series GMDSS Radio Station consists of two models' RC-1800F (floor deck mount) and 1800T (tabletop mount). Equipment are controlled using FURUNO’s radio interface protocol 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 protocol developed by FURUNO for remote control of radio equipment.
1.3 Equipment Description Regulations require that all equipment be powered while the vessel is underway. SSB Radiotelephone For ship-ship and ship-station radio communications in the MF/HF band (1.6-26.
1.4 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 MF/HF DSC Terminal or NBDP Terminal, the Tx and Rx frequencies and class of emission are automatically set on the SSB Radiotelephone and then the message is transmitted. Two printers are supplied and one is dedicated to the Inmarsat C.
Turning off the system Reverse the order shown at the previous page to turn off the system. (Example for RC-1800F-15A) Battery Charger Inmarsat C (24 VDC backed up by battery) FS-1570 (24 VDC backed up by battery) PR-850AR PR-300 24 VDC Battery 100/110/220 VAC (Main Switch) Turning off the printer interface 1. Remove four screws to remove the control panel. 2. Turn off the switch shown below. IF8 I 500 ON OF F 3. Attach the control panel.

Chapter 2 MAINTENANCE 2.1 Control Panel The figure which follows is an exploded view of the Control Panel. 4 3 STOP 5 BUZZER switch Dimmer knob: right side of console (refer to page 1-1) (RC-1800T: option) Voltmeter and Ammeter 2 EMG LIGHT 1 switch BATTERY MONITOR lamp 6 BATTERY CHARGER switch For flooded lead-acid battery: Control description 1. EMG LIGHT switch Turns the emergency lamps at the top of the console on/off (RC-1800T: option).
2. BATTERY MONITOR lamp IN USE lamp (AC power failure: orange) Lights to alert that the AC power has failed and the radio equipment is being powered by the radio battery (DC power) alone. When lit, only the equipment related to distress communication are powered. (Power is not supplied to console lights.) LOW VOLT lamp (low battery voltage: red) Lights to alert that the battery voltage is below 22 VDC. (The aural alarm sounds until the voltage becomes higher than 22 VDC.) 3.
2) Confirming charging Confirm that the BATTERY CHARGER switch on the Control Panel is set to AUTO. Further, confirm that the voltage shown on the battery voltage meter on the Control Panel is normal (between 26.5 VDC and 27.0 VDC). 3) 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 organic solvents, thinner, gasoline, benzine or alcohol to clean the battery. (They may crack the case.
WARNING 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 harmful to the human body, 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.
2. Cleaning floppy disk drives The heads in the floppy disk drive of the terminal unit and Inmarsat-C should be cleaned regularly to prevent damage to floppy disks. Use a cleaning floppy disk. (FURUNO can supply a cleaning floppy disk. It is type MCD-2, code no. 000-116-420.) Procedure 1. Insert ∞a cleaning floppy disk 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.
Loading roll paper This section shows you to load the roll paper. CAUTION Keep fingers away from edges on the printer and cover. Edges can cut fingers. Observe the following cautions when loading the paper: • To prevent paper skewing or jamming, be sure the paper is positioned correctly. • Never turn the platen knob too fast—gears may be damaged.
Removing remaining paper 1. Press P. PARK the switch to back up the paper. Turn off the power. 2. Unfasten screws A and push back B (for both right and left) shown below to remove the printer cover. C Paper Paper Cover Screw A B Printer cover 3. Swing out the paper cover by 100° to 120° then lift it from the right-hand side to remove it from the printer. 4. Referring to the figure above, lift the paper bail C.
6. Pull the paper bail forward. Manually feed the paper over the paper guide bar and under the platen. Turn the platen knob clockwise to feed the paper so it reaches the paper guide bar. Paper Guide Bar Paper Release Lever Platen Knob Paper Bail Platen 7. Unlock the paper release lever to adjust the paper and then lock it. 8. Slide the left and right guide rings to position the paper straightly. Guide Ring Guide Ring 9. Replace the paper cover, the printer cover and roll paper stay.
