●Servicing Precautions
In servicing the FCP-7101/FX-7102, observe the following.
DANGER
Never remodel the medical electronic equipment.
If remodelled, the equipment may not ensure safe operation,
thereby causing accidental hazards to the patient and
operator.
CAUTION
yThe service manual is intended for the service engineers
of Fukuda representatives and the technical staff
concerned with medical electronic equipment. Servicing,
reassembling, and adjustment shall be performed by
autorized service engineers.
yPrepare proper facilities and tools when servicing.
yBe sure to follow the instructions of operation manual
when operating the instrument. For operating precautions,
refer to the operation manual.

iii
CAUTION
Disassembling/Reassembling Precautions
yBe sure to turn the power off and disconnect the power supply cord
from the wall outlet. Then start disassembling the instrument.
yWhen removing the main PC board, remove the battery in advance.
yTake care not to disconnect and connect the key panel and sensor
board from/to the connector too frequently. Too frequent disconnection
and connection of these units may cause poor contact.
yUse proper screwdrivers to loosen screws.
yWhen reassembling, make sure all screws are tightened to original
positions and all disconnected connectors are reconnected properly.
PC Board Handling Precautions
yPC boards are equipped with extremely sensitive devices to static
electricity.
yPC boards are sensitive electronic assemblies. Take proper measures
for removed PC boards, e.g. put them in a conductive bag.
yHandle PC boards carefully. Giving an impact to them may damage
devices mounted onto them.
yNever remove a PC board or connect the connector to it when it is
supplied with power.
CAUTION
If you find a value which exceeds the allowable level, be sure to let the
user avoid using the instrument. If the user operates the instrument as it
is, he/she may receive an hazardous accident.
