devices.
4. Use only an antistatic solder removal device. Some solder
removal devices not classified as "antistatic (ESD protected)" can
generate electrical charge sufficient to damage ES devices.
5. Do not use freon-propelled chemicals. These can generate
electrical charges sufficient to damage ES devices.
6. Do not remove a replacement ES device from its protective
package until immediately before you are ready to install it. (Most
replacement ES devices are packaged with leads electrically
shorted together by conductive foam, aluminum foil or
comparable conductive material).
7. Immediately before removing the protective material from the
leads of a replacement ES device, touch the protective material to
the chassis or circuit assembly into which the device will be
installed.
CAUTION: Be sure no power is applied to the chassis or circuit,
and observe all other safety precautions.
8. Minimize bodily motions when handling unpackaged replacement
ES devices. (Otherwise harmless motion such as the brushing
together of your clothes fabric or the lifting of your foot from a
carpeted floor can generate static electricity (ESD) sufficient to
damage an ES device).

4.1.1. SIMPLIFIED FAULT FINDING DATA
Simplified Self-Diagnostic System facilitates finding the cause of the fault. A 3-digit fault code
will be displayed in F.I.P.
The Simplified Fault finding data is stored in the Memory IC (IC6005). This data is cleared after it
is displayed, and then the POWER button is pressed back on.
