TROUBLESHOOTING
This chapter provides the information necessary for the maintenance and
checking of the FELCOM 15. Please review the safety information at the
beginning of this manual before attempting any maintenance procedures.
9.1 General Checking and Maintenance
Turn off the power before conducting any maintenance procedures other than
the cleaning of the terminal unit.
NOTICE
Do not apply paint, anti-corrosive sealant or contact spray
to coating or plastic parts of the equipment.
Those items contain organic solvents that can damage coating
and plastic parts, especially plastic connectors.
Cleaning the terminal unit
Wipe the LCD carefully to prevent scratching, using tissue paper and an LCD
cleaner. To remove dirt or salt deposits, use an LCD cleaner, wiping slowly with
tissue paper so as to dissolve the dirt or salt. Change paper frequently so the
salt or dirt will not scratch the LCD. Do not use solvents such as thinner, acetone
or benzine for cleaning; they can remove paint and marks or deform the
equipment.
Checking connectors and earth terminal
Check that the connectors and earth terminal on the terminal unit are tightly
fastened. If the copper strap (earth material) has rusted, clean it.
Floppy disk drive head
The floppy disk is coated with a magnetic material which stores the information
entered into the disk. If this material is damaged by foreign material adhering to
the disk drive head it may not be possible to read from or write to the disk. Clean
the head regularly with a cleaning floppy disk to prevent loss of data.
When the power can’t be turned on
When the terminal unit cannot be turned on do the following:
• Check that the power cable connector on the rear panel of the terminal unit for
tightness.
• Check if the ship’s mains switchboard is turned on.
• Have a qualified technician check the power voltage at the power connector
on the rear of the terminal unit.
