Important Notes
When you need to transport the unit, package it in the box
(including padding) that it came in, if possible. Otherwise,
you will need to use equivalent packaging materials.
If using the music rest, do not apply excessive force to it.
Some connection cables contain a resistor. Do not connect
such cables to this device. Doing so may make the volume
extremely low or inaudible. Please use connection cables
not containing a resistor.
Do not insert your finger into the bass reflex port (hole) of
the speaker box. The edge of the wood may injure you.
Never insert foreign objects (flammable material, coins,
wire, etc.) into the bass reflex port (hole) of the speaker
box. Doing so may cause damage or malfunctions.
Floppy Disk Handling
(Using Optional Floppy Disk Drive)
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).
Recommended temperature range: 10–50 degrees C
(50–122 degrees F).
Do not expose floppy disks to strong magnetic fields,
such as those generated by loudspeakers.
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.
fig.DiskProtect.e.eps
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.
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.
