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 manufacturerís
instructions.
CAUTION: The battery pack used in this device may
present a fire or chemical burn hazard if mistreated.
Do not disassemble, heat above 100C (212F) or
incinerate.
Dispose of used battery promptly.
Keep away from children.
CAUTION: Changing the back up battery.
ï 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.
ï If a cell has leaked or vented, it should be replaced
immediately while avoiding to touch it without
any rotection.
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 setís 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...
ï The temperature of the soldering-iron tip should be
about 270C.
ï Do not apply the tip more than three times to the
same pattern.
ï Handle patterns with care; never apply force.
Caution: Remember that hard disk drives are easily
damaged by vibration. Always handle with care.
