Service and Inspection Precautions
1. Obey
precautionary
markings
and
instructions
Labels and stamps on the cabinet, chassis, and components identify
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 components that have
particularly important safety functions; 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 inclusion
of insulating materials (tubes and tape) and the mounting 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, therefore, be sure to duplicate
the original layout.
4. Inspect after completing service
After servicing, inspect to make sure that all screws, components,
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...
· The temperature of the soldering-iron tip should be about 270C.
· 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.
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: Danger of explosion if battery is incorrectly
replaced. Replace only with the same or equivalent type
recommended by the manufacturer. Discard used batteries
according to the manufacturer'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.
