CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous ra-
diation exposure.
Notes on chip component replacement
· Never reuse a disconnected chip component.
· Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
Flexible Circuit Board Repairing
· Keep the temperature of the soldering iron around 270 ° C dur-
ing repairing.
· Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
· Be careful not to apply force on the conductor when soldering
or unsoldering.
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 flow) 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.
On power sources
· Use house curre nt, nikel metal hyd ride
rechargeable battery, LR6 (S G) battery, or car
battery.
· For use in your house: For the s uppl ied battery
charging s ta nd, use the AC po wer adaptor
s uppl ied with this recorder. Do not use an y other
AC power adaptor s ince it ma y cause the recorder
to malfuncti on.

NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electro-
static 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 flexible board is easily damaged and should be handled with
care.
NOTES ON LASER DIODE EMISSION CHECK
Never look into the laser diode emission from right above when
checking it for adjustment. It is feared that you will lose your sight.
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
(LCX-5R)
The laser diode in the optical pick-up block may suffer electro-
static break-down easily. When handling it, perform soldering
bridge to the laser-tap on the flexible board. Also perform mea-
sures against electrostatic break-down sufficiently before the op-
eration. The flexible board is easily damaged and should be handled
with care.
OPTICAL PICK-UP FLEXIBLE BOARD
SECTION 1
SERVICING NOTES
· In performing the repair with the power supplied to the set, re-
moving the MAIN board causes the set to be disabled.
In such a case, fix a convex part of the open/close detect switch
(S804 on MAIN board) with a tape in advance.
Handle the FLEXIBLE board (over write head) with care, as it
has been soldered directly to the MAIN board.
In repairing the component side of MAIN board, connect the
FLEXIBLE board (over write head) and the MAIN board with
the lead wires in advance. (See page 8)

· The shipment data will be cleared when the NV is reset. There-
fore, change the NV adjusted values following the Change of
NV Adjusted Values immediately after the NV was reset. (See
page 19)
· The set having the microcomputer version 1.000 to 1.300 re-
quires the patch data in the nonvolatile memory (IC802) to be
rewritten using the application, when the MAIN board was re-
placed. (See page 27)
On the set having the microcomputer version 1.400 or later, re-
writing the patch data is unnecessary.
· Replacement of CXD2677-205GA (IC801) used in this set re-
quires a special tool.
