BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostat-

charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic break-down and also
use the procedure in the printed matter which is included in the
repair parts.
The fl exible board is easily damaged and should be handled with
care.

NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused
on the disc refl ective surface by the objective lens in the optical
pickup block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.

Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40 °C higher
• Unleaded solder melts at a temperature about 40 °C higher
than ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.

Caution: The printed pattern (copper foil) may peel away if the
heated tip is applied for too long, so be careful!
• Strong viscosity
Unleaded solder is more viscou-s (sticky, less prone to fl ow)
than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.

• Do not subject the unit to strong shocks or vibrations.
• Do not place the unit in a location subject to mechanical
vibration or at an unstable location.
• Do not move the unit while the power cord is connected to a
wall outlet.
• Do not disconnect the power cord while the unit is recording or
playing a track.
• Do not use the unit in a place subject to extreme changes in
temperature (a temperature gradient greater than 18°F (10°C)/
hour).

• Do not attempt to replace or upgrade the hard disk drive by
yourself, as this may cause the unit to malfunction.

On data back up
Audio data and system settings stored on the unit’s hard disk may
be lost during repairs done to the unit. Before taking the unit in for
repairs, it is recommended that you record the settings on a piece
of paper and that you use the Back Up function to back up the data
to a shared folder on your computer or a USB hard disk drive (see
“Backing up and restoring audio data” on page 104).
Data on the unit’s HDD is subject to damage during normal
operations. To prevent the loss of data, you should back up the data
on a regular basis. Please note that we cannot take responsibility
for any data that may be lost or
