1. Obey precautionary markings and instruc-
tions
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.

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 occurrence; 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.
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 270
• 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.
