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

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
– 2 –
EXPLODED VIEW PARTS LIST
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°C.
• 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.
