3) Procedures of Cleaning
a) Wet type
Dispense the cleaning solution onto the lint-
free cleaning disk through the cutout- in the disk
jacket. Insert the cleaning disk and activate the
drive. Load head and rotate disk for 2 v 3 minutes.
Eject cleaning disk and wait for another 2 ^ 3
minutes to dry heads.
As the cleaning disk is high in light transmittance,
cover the index hole by a semi-transparent material
such as tracing paper, or color in black the index
hole circular area of the disk, when the head are not
loaded on the cleaning disk.
b) Dry type
Abrasive type dry cleaning disk may also be used for
a hard deposit on the disk. 1 / 2 v 1 minutes would be
sufficient. Wet type finish would be recommended
after dry type cleaning.
4) Other Comments
a) Please contact maintenance or service facilities if
the above procedures can not recover the good per­
formance .
b) The diskette medium is weak for abrasion in temper­
atures below the specified range (below 10°C or
50°F). The durability in such low temperatures
are different largely for diskette brands.
c) Dry type wculc be usable once a month, but we don't
recommend to use two times or more in a month.
c) Recommended to use dry type limitted by maintenance
personnel only, or limited to use by users when
frecuent errors or disk scratches are found.
