HCD-LF10
The laser diode in the optical traverse unit block may suffer
electrostatic 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
The laser beam on this model is concentrated so as to be focused on
the disc reflective surface by the objective lens in the optical traverse
unit. Therefore, when checking the laser diode emission, observe
from more than 30 cm away from the objective lens.
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 viscou-s (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.

NOTE  OF  REPLACING  THE  DMB07  BOARD-1
When replacing the DMB07 board, since the adjustment value is
not set up correctly, “Drive Auto Adjustment” can’t be performed.
In this case, initialize memory in the following procedures.
Procedure:
1. Set the test mode. (See page 26)
2. Press the [2]  key on the remote commander, and set the
“DRIVE MANUAL OPERATION”. (See page 28)
3. Press the [6] key on the remote commander, and set the “2-6,
Memory Check”. (See page 30)
4. Press the [CLEAR] key on the remote commander, and initialize
memory.
NOTE  OF  REPLACING  THE  DMB07  BOARD-2
New part of EEPROM (IC204, IC903) on the DMB07 board cannot
be used. Therefore, if the mounted DMB07 board is replaced,
exchange new EEPROM with that used before the replacement.
