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 0 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.
CAUTION: Changing the back up battery.
• Overcharging, short circuiting, reverse charging, multilation or
incineration of the cells must be avoided to prevent one or more of
the following occurrences; release of toxic materials, release of
hydrogen and/or oxygen gas, rise in surface temperature.
• If a cell has leaked or vented, it should be replaced immediately
while avoiding to touch it without any protection.
