SERVICING NOTES
UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the
leadfree 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.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specifi ed herein may result in hazardous
radiation exposure.
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
OR BASE UNIT
The laser diode in the optical pick-up block may suff er electrostatic
break-down because of the potential diff erence 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 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.
CAUTION
Caution – use of controls or adjustments or performance of proce-
dures other than those specifi ed herein may result in hazardous ra-
diation exposure.
This appliance is classifi ed as a CLASS 1 LASER product under
IEC 60825-1:2014.
When unpacking the carton, be sure that two people handle the unit.
Dropping the unit may cause personal injury and/or property dam-
age.
For customers in EA
CAUTION
Risk of explosion if the battery is replaced by an incorrect type.
Do not expose batteries or appliances with battery-installed to ex-
cessive heat, such as sunshine and fi re.
