11-3 Replacing On-board Parts
CAUTION
If any electrical parts need to be replaced, it is recommended to replace the entire
board whenever possible.
Most electrical parts on the board are soldered into a very small area, and attempts to
replace these on-board electrical parts present risks of damaging the board as well as
other electrical parts.
CAUTION
When operating the equipment with its housing removed, a safety check will be
required after it has been assembled. Contact the related department of Fukuda
Denshi (International Sales Division) beforehand when operating the equipment
with its housing removed.
In order to avoid damage to electric parts by static electricity, operate the
equipment on a working desk with anti-static mat. Furthermore, make sure to wear
an anti-static wrist strap designed to discharge static electricity from human body
when operating the equipment.
Keep PC boards and electric parts that have been removed from the equipment in a
conductive bag in order to protect them from static electricity, liquid spills and
shock.
When replacing parts, make sure to only use parts that are specified for the
equipment.
Use proper screwdrivers to tighten or loosen screws.
Make sure to use screws that are specified by Fukuda Denshi.
When reassembling, make sure all screws are tightened to original
positions and all disconnected connectors are reconnected properly. After
assembling the equipment, check that there are no foreign objects in the connector
sockets or in the battery terminal.
