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 the AC/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 on the screen.)
