1. Obey precautionary markings and
instructions
Labels and stamps on the cabinet, chassis, and components iden-
tify areas requiring special precautions. Be sure to observe these
precautions, as well as all precautions listed in the operating
manual and other associated documents.
2. Use designated parts only
The set’s components possess important safety characteristics,
such as noncombustibility and the ability to tolerate large
voltages. Be sure that replacement parts possess the same safety
characteristics as the originals.Also remember that the ( mark,
which appears in circuit diagrams and parts lists, denotes com-
ponentsthathaveparticularlyimportantsafetyfunctions;be extra
sure to use only the designated components.
3. Always follow the original design
when mounting parts and routing wires
The original layout includes various safety features, such as in-
clusion of insulating materials (tubes and tape) and the mount-
ing of parts above the printer board. In addition, internal wiring
has been routed and clamped so as to keep it away from hot or
high-voltage parts. When mounting parts or routing wires. there-
fore, be sure to duplicate the original layout.
Caution Markings for Lithium/Ion Battery - The following or
similar texts shall be provided on battery pack of equipment or
in both the operating and the service instructions.
CAUTION:Dangerofexplosion if battery is incorrectlyreplaced.
Replace only with the same or equivalent type recommended by
the manufacturer. Discard used batteries according to the manu-
facturer’s instructions.
CAUTION: The battery pack used in this device may present a
fire or chemical burn hazard if mistreated. Do not disassemble,
heat above 100˚C (212˚F) or incinerate.
Dispose of used battery promptly.
Keep away from children.
4. Inspect after completing service
After servicing, inspect to make sure that all screws, compo-
nents, and wiring have been returned to their original condition.
Also check the area around the repair location to ensure that
repair work has caused no damage, and confirm safety.
5. When replacing chip components...
Never reuse components. Also remember that the negative side
of tantalum capacitors is easily damaged by heat.
6. When handling flexible print boards...
• Thetemperatureofthesoldering-irontipshouldbeabout270C.
• Do not apply the tip more than three times to the same pattern.
• Handle patterns with care; never apply force.
Caution: Remember that hard disk drives are easily damaged
by vibration. Always handle with care.
