SECTION  1
SERVICING  NOTES
The SERVICING NOTES contains important information for servicing. Be sure to read this section before repairing the unit.
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.
REPLACING  THE  LITHIUM  BATTERY  OF  THE  REMOTE  
COMMANDER (Except Russian model only)
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.
