SECTION  1
SERVICING  NOTES
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.
ABOUT  CHECKING  THE  OPERATION
When checking the operation of this unit, connect a USB device 
to this unit.
Refer to the support site written in the operating instruction for the 
details about the compatibility of a USB device.
NOTE  OF  REPLACING  THE  KEY  BOARD
When the KEY board is defective, exchange the FRONT PANEL 
ASSY (Ref. No. FP1).
NOTE  OF  REPLACING  THE  IC603  ON  THE  MAIN  BOARD
IC603 on the MAIN board cannot exchange with single. When this 
part is damaged, exchange the complete mounted board.
Maintenance
Replacing the lithium battery of the 
remote commander
When the battery becomes weak, the range 
of the remote commander becomes shorter. 
Replace the battery with a new CR2025 
lithium battery. Use of any other battery may 
present a risk of fire or explosion.
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 assure 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.
Cleaning the connectors
The unit may not function properly if the 
connectors between the unit and the front 
panel are not clean. In order to prevent this, 
detach the front panel (page 6) and clean the 
connectors with a cotton swab. Do not apply 
too much force. Otherwise, the connectors 
may be damaged.
WARNING
Battery may explode if mistreated.
Do not recharge, disassemble, or dispose 
of in fire.
+ side up
Notes
ˎ For safety, turn off the ignition before cleaning 
the connectors, and remove the key from the 
ignition switch.
ˎ Never touch the connectors directly with your 
fingers or with any metal device.
