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 soldering iron around 270 °C during 
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.
CAUTION
Use of controls or adjustments or performance of procedures 
other than those specifi ed herein may result in hazardous radia-
tion exposure.

SECTION  1
SERVICING  NOTES
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 fl exible 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.
If the optical pick-up block is defective, please replace the whole 
optical pick-up block.
Never turn the semi-fi xed resistor located at the side of optical 
pick-up block.

semi-fixed resistor
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.
The SERVICING NOTES contains important information for servicing. Be sure to read this section before repairing the unit.
REPLACING  THE  LITHIUM  BATTERY  OF  THE  REMOTE  
COMMANDER
Under normal conditions, the battery will last 
approximately 1 year. (The service life may be 
shorter, depending on the conditions of use.)
When the battery becomes weak, the range of the 
remote commander becomes shorter.
CAUTION
Danger of explosion if battery is incorrectly 
replaced. Replaced only with the same or 
equivalent type.
Notes on the lithium battery
ˎ Keep the lithium battery out of the reach of children. 
Should the battery be swallowed, immediately 
consult a doctor.
ˎ Wipe the battery with a dry cloth to ensure a good 
contact.
ˎ Be sure to observe the correct polarity when installing 
the battery.
ˎ Do not hold the battery with metallic tweezers, 
otherwise a short-circuit may occur.
WARNING
Battery may explode if mistreated. Do not 
recharge, disassemble, or dispose of in fire.
