4.4 Cleaning and Handling
4.4.1 Escutcheon
(1) Cleaning the escutcheon
① Follow the same procedures as described for replacing the display section (LCD panel) in
section 4.3.3 (3), and open the display section so that the rear side of the escutcheon can be
cleaned.
② Wipe the escutcheon with a soft clean cloth. If the escutcheon is heavily dirtied, soak the cloth
in a neutral detergent, and wipe the display. Do not use alcohol or paint thinner, etc.
4.4.2 Floppy disk drive
(1) Cleaning the floppy disk drive
When the floppy disk drive is used for a long time, magnetic particles or dust from the disk may
adhere onto the head surface. This can cause the reading and writing processes to be inhibited.
Clean the head periodically (once every two months) with the following procedure.
a) Recommended cleaning disk
Maker : Japan Morex
Type
: Morex cleaning floppy for double-sided 3.5-inch
Method : Dry
b) Cleaning method
① Insert the cleaning disk into the floppy disk drive to be cleaned.
② Start the cleaning program, and follow the instructions given on the screen.
③ When the program is completed, eject the cleaning disk.
Note 3) There is a limit to the number of times the cleaning disk can be used. When the limit is
reached, replace the cleaning disk with a new one. Refer to the cleaning disk manual
for the limit.
(2) Handling floppy disks
Observe the following items to ensure that the floppy disk can be used for a long time.
a) Precautions for use
① Never tough the magnetic surface with hands.
Finger prints on the magnetic surface will inhibit the
reading process.
② Do not touch the floppy disk with hands dirtied with oil or
iron chips.
③ Do not place the floppy disk near cigarette smoke.
Do not apply solvents on the magnetic surface.
④ Always attach the index label to the correct position so that it will
not come off. Do not layer the index labels.
⑤ Fill in the index label before attaching it to the floppy disk.
When writing on a label already attached to the floppy disk, use a
felt-tip pen, etc.
⑥ Carefully insert the floppy disk into the drive with it facing the correct
direction. Rough handling during insertion and ejection could damage
the floppy disk.
⑦ When bringing the floppy disk inside from outdoors where the
temperature and humidity difference are great from indoors,
wait at least 30 minutes before starting use.
