Important Notes
Servicing
• If you return this device for servicing, the contents of
memory may be lost. Please store important contents on
USB memory, or make a note of the contents. We take
utmost care to preserve the contents of memory when
performing service, but there may be cases when the stored
content cannot be recovered because the memory section
has malfunctioned. Please be aware that we cannot accept
responsibility for the recovery of lost memory content or for
any consequences of such loss.
Other Cautions
• Stored content may be lost due to a malfunction of the
device or because of inadvertent operation. You should
back up important content on USB memory as a safeguard
against such loss
• We cannot accept responsibility for the recovery of any
content lost from internal memory or USB memory, or for
the consequences of such loss.
• Do not apply excessive force to the buttons, knobs, or
input/output jacks, since this may cause malfunctions.
• When connecting or disconnecting cables, grasp the plug
(not the cable) to prevent short circuits or broken
connections.
• Please enjoy your music in ways that do not inconvenience
other people nearby, and pay particular attention to the
volume at nighttime. Using headphones will allow you to
enjoy music without having to be concerned about others.
• 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.
