• Install the unit on a solid, level surface in an area free 

from vibration. If the unit must be installed at an angle, 
be sure the installation does not exceed the permissible 
range.

603

• Avoid using the unit immediately after it has been moved 

to a location with a level of humidity that is greatly 
different than its former location. Rapid changes in the 
environment can cause condensation to form inside the 
drive, which will adversely affect the operation of the 
drive and/or damage floppy disks. When the unit has 
been moved, allow it to become accustomed to the new 
environment (allow a few hours) before operating it.

• To insert a disk, push it gently but firmly into the drive—

it will click into place. To remove a disk, press the EJECT 
button firmly. Do not use excessive force to remove a disk 
which is lodged in the drive.

605b

• Never eject a disk while reading or writing is in progress, 

since that can damage the magnetic surface of the disk, 
rendering it unusable. (The disk drive's indicator will 
light up at full brightness when the drive is busy reading 
or writing data. Ordinarily, the indicator will be less 
brightly lighted, or be extinguished.)

606

• Remove any disk from the drive before powering up or 

down.

607

• To prevent damage to the disk drive’s heads, always try 

to hold the floppy disk in a level position (not tilted in 
any direction) while inserting it into the drive. Push it in 
firmly, but gently. Never use excessive force.

608

• To avoid the risk of malfunction and/or damage, insert 

only floppy disks into the disk drive. Never insert any 
other type of disk. Avoid getting paper clips, coins, or 
any other foreign objects inside the drive.

651

• Floppy disks contain a plastic disk with a thin coating of 

magnetic storage medium. Microscopic precision is 
required to enable storage of large amounts of data on 
such a small surface area. To preserve their integrity, 
please observe the following when handling floppy disks: 
• Never touch the magnetic medium inside the disk.
• Do not use or store floppy disks in dirty or dusty 

areas.

• Do not subject floppy disks to temperature extremes 

(e.g., direct sunlight in an enclosed vehicle). Recom-
mended temperature range: 0 to 50° C (50 to 122° F).

• Do not expose floppy disks to strong magnetic fields, 

such as those generated by loudspeakers.

652

• Floppy disks have a “write protect” tab which can protect 

the disk from accidental erasure. It is recommended that 
the tab be kept in the PROTECT position, and moved to 
the WRITE position only when you wish to write new 
data onto the disk.

653

• The identification label should be firmly affixed to the 

disk. Should the label come loose while the disk is in the 
drive, it may be difficult to remove the disk.

654

• Store all disks in a safe place to avoid damaging them, 

and to protect them from dust, dirt, and other hazards. 
By using a dirty or dust-ridden disk, you risk damaging 
the disk, as well as causing the disk drive to malfunction.

655

• Disks containing performance data for this unit should 

always be locked (have their write protect tab slid to the 
“Protect” position) before you insert them into the drive 
on some other unit (except the PR-300, or a product in the 
HP-G/R, MT, KR, or Atelier families), or into a 
computer’s drive. Otherwise (if the write protect tab 
remains in the “Write” position), when you perform any 
disk operations using the other device’s disk drive (such 
as checking the contents of the disk, or loading data), you 
risk rendering the disk unreadable by this unit’s disk 
drive.
