4. Caution in removal and making wiring connection to
the parts for the automobile.
Disconnect the battery terminal after turning the igni-
tion key off. If wrong wiring connections are made with
the battery connected, a short circuit and/or fire may
occur. If extensive damage is caused due to negligence
of repair, the legal responsibility shall be with the repair-
ing company.
5. Cautions regarding chips.
Do not reuse removed chips even when no abnormal-
ity is observed in their appearance. Always replace them
with new ones. (The chip parts include resistors, ca-
pacitors, diodes, transistors, etc). The negative pole of
tantalum capacitors is highly susceptible to heat, so
use special care when replacing them and check the
operation afterwards.
6. Cautions in handling flexible PWB.
Before working with a soldering iron, make sure that the
iron tip temperature is around 270-C. Take care not to
apply the iron tip repeatedly (more than three times) to the
same patterns. Also take care not to apply the tip with
force.
