Extension:
The Floppy Disk may be extended up to 4 drives (2 units) using the daisy-chain connection. It is
therefore important to change the connection of each unit if the extension is made. The extension
should be done according to "Method of extension" described hereafter.
A
wrong connection
destroys the drive signal circuit. When extending the disk, an exclusive extension unit MZ-80FDK
m ust be used.
Ambient temperature:
The diskette used as a recording medium for the MZ-80FD is sensitive to temperature change:
easily expanding or contracting; therefore, the ambient temperature should be kept below 25°C
during continuous operation, and below 27°C during intermittent operation.
Power supply:
Supply voltage should be local voltage. Excessively high or low voltage could result in faults and
thus insufficient performance.
Do not connect the system to the same power line as other apparatus (e.g. a large-scale motor)
which cause noise. If the system malfunctions due to the noise from the power line, connect the
system to the power line that has been cleared of mixed noise using a power line filter. Turn on or
off the system power supply while the diskette is out of the drive, otherwise a malfunction occurs.
Humidity and dust:
The Floppy Disk, a precision mach ine, is easi Iy damaged by excessively high humidity. Do not use
this unit in a location that is high in humidity or is dusty. (Working ambient humidity range: 20% to
80%)
Water and foreign matter:
It is dangerous to use this unit with water or other liquid or metallic objects such as a needle, pin
or the like remaining therein. Take care not to allow any extraneous matter to get into the unit.
Especially if any liquid (including water) or powdery matter gets into the unit, be sure to contact the
dealer from which you have purchased the unit.
The same caution is required for the diskette. Do not operate the Floppy Disk while smoking or
drinking.
Installing conditions and shock:
The Floppy Disk consists of precision mechanism and electronic parts. Do not use it in a location
that is subjected to too !.igh or too low temperatures, radical temperature changes, much vibration or
dust. Do not give any shock to the unit by violently putting or dropping object(s) on it. Keep this unit
away from
loudspeakers, televisions, tape recorders or other magnetism-generating apparatus,
otherwise it may cause a malfunction, or data or text recorded on the diskette may be erased.
Only operate the unit on a level surface. Locate the signal cables (flat cable, etc.) as far as possible
from other apparatus and power cords.
