If the product is defective, please contact the store where you bought it.
SHARP is not responsible for damage incurred during, or as a result of, operation.
CAUTION
'-'
1) Do not use this unit where rapid increases or decreases in temperature occur
or in humid or dusty environment. This unit consists of precision parts, such
as LSI circuits, that can be affected by the operating environment. Do not
expose the unit to direct sunlight.
2) Do not bump or drop this unit, or turn it upside down.
3) Use this device horizontally on a stable, strong support.
4) To prevent electrical noise (RF interference), keep this unit away from all
devices that are likely to generate such.
5) Do not open or push the disk holder during operation (while the BUSY lamp
is on).
6) Be sure to insert the disk along the disk guides for correct insertion. (See page
4. Inserting a disk into the drive.)
7) Clean the head periodically. (See page 6.)
8) Do not operate this unit continuously more than fifty times. If you do, a
malfunction may occur. (Avoid this by programming.)
9) Do not put anything on top of this unit, not even a cloth.
10) Clean the unit with a dry, ~oft cloth. Do not use volatile liquids (alcohol,
benzine, thinner, etc.) or a wet cloth.
11) If MZ disk errors occur frequently, clean the head. If errors continue, contact
the store where you bought the unit.

MZ DISK
(1) Disk
This drive uses 2.8-inch double-sided MZ disks. A disk is a flexible magnetic
sheet that stores programs and data. It is permanently contained in a stiff
jacket. The magnetic sheet is viewed th rough the head window. The next
figure shows a standard disk.

Side A label
Drive hole
When the disk is mounted in the disk drive, the rotary spindle of the drive
frts snugly into this hole. The drive's guide pin fits into the guide hole and
helps turn the disk.
Head window
The magnetic head of the disk drive reads and writes data to the disk,
touching it through this window.
Note:
Do not touch the magnetic material - be sure to handle the disk only by its
jacket.

Disk holder
1) Press the EJECT button to open the disk holder.
2) Insert the disk along the disk guides with the head window at the front.
(Hold the disk by the edge of its jacket.) Data can be read or written
on side A or side B. Check the side to be used - it is indicated on the
jacket.
3) Push the disk in lightly until it stops, then close the disk holder. Be sure
to insert the disk along the disk guides. Never close the disk holder unless
the disk is fully inserted.
(3) Write-protect tab
This tab is removed to prevent 'data on the disk from being deleted accidentally. When this tab is removed, no data can be saved to the disk,
although data can be read.
Some master disks are supplied by SHARP with their tabs already removed.
Sides A and B have one write protection tab each, so each side can be write
protected independently.
The write-protect tab is on the right side of the side of the disk it protects
(as shown in the figure on page 3).

(4) Data read/write
The only operation the user can perform on this unit is removing and
inserting disks. All data operations are controlled by the computer. Refer to
the manual for the software in use.

1. Follow the instructions on the protective envelope of the disk.
2. When disks are not in use, store them vertically in their envelopes in a disk
storage box. Do not lean disks against anything. This will bend them.
3. Do not bend or fold disks. A bent or folded disk is useless.
4. Information should be written on a label before it is attached to a disk.
When information must be written on a label already attached to a disk,
use a soft-tipped pen (felt making pen, etc.) Do not use a pencil or ballpoint pen - you can ruin your disk this way.
S. Do not place disks near magnetic materials. This may destroy programs
and data on the disk.

HOW TO CLEAN THE DISK HEAD
You must clean the disk head regularly - determine the interval of cleaning
based on the degree of oxide buildup on the head. Using a dirty head will cause
disk errors and much frustration.
1) Open the disk holder by pressing the EJECT button.
2) Notice the head at the back of the disk table.
3) Wipe the head surface with an applicator moistened with head-cleaning liquid.
(Perform this procedure in the similar way as cleaning a tape recorder head.)
/ Disk holder
Disk table (Disk shaft)
Note:
1. Use only the specified applicator to clean the head.
2. Purchase head cleaning liquid and applicators at an electrical store. (Use a
new applicator for each cleaning - use several if the first one becomes dirty.)
3. Cotton swabs available at any drugstore may be used as applicators.
