SERVICING NOTES
UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the lead-
free mark (LF) indicating the solder contains no lead.
(
Caution:
Some printed circuit boards may not come printed with
the lead free mark due to their particular size)
: LEAD FREE MARK
Unleaded solder has the following characteristics.
• 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.
Soldering irons using a temperature regulator should be set to
about 350 °C.
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 viscous (sticky, less prone to
fl
ow)
than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.
• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostat-
ic break-down because of the potential difference generated by the
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 re
fl
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.
RELEASING THE DISC TRAY LOCK
The disc tray lock function for the antitheft of an demonstration
disc in the store is equipped.
Releasing Procedure:
1. Press
[
?/1
] button to turn the power on.
2. Press the [FUNCTION] button to select CD function.
3. While pressing the [
x
] button, press the [
Z
] button for more 5
seconds).
4. The message “UNLOCKED” is displayed and the disc tray is
unlocked.
Note:
When
“
LOCKED
”
is displayed, the slot lock is not released by
turning power on/off with the
[
?/1
]
button.
NOTE THE IC1, IC5 AND IC13 ON THE USB MICOM
BOARD REPLACING
IC1, IC5 and IC13 on the USB MICOM board cannot exchange
with single. When IC1, IC5 and IC13 on the USB MICOM board
are damaged, exchange the entire mounted board.
