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 manu-
facturer. Discard used batteries according to the
manufacturer’s instructions.

CAUTION: The battery pack used in this device
may present a fi re or chemical burn hazard if mis-

treated. Do not disassemble, heat above

°C

(

140

°F) or incinerate. Dispose of used battery

promptly. Keep away from children.

CAUTION: Changing the back up battery.

•

Overcharging, short circuiting, reverse charg-

ing, multilation or incineration of the cells must
be avoided to prevent one or more of the fol-
lowing 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.

Service and Inspection Precautions

1. Obey precautionary markings and

instructions

Labels and stamps on the cabinet, chassis, and
components identify areas requiring special pre-
cautions. 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 charac-
teristics as the originals. Also remember that the

mark, which appears in circuit diagrams and

parts lists, denotes components that have particu-
larly 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 fea-
tures, 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 du-
plicate 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 confi rm
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.
