All other names of systems, products and services
in this manual are trademarks or registered trade-
marks of their respective owners. In this manual,
the (TM) or (R) mark are not specified.
Caution Markings for Lithium/Ion Battery - The
following or similar texts shall be provided on
battery pack of equipment or in both the operat-
ing and the service instructions.
CAUTION: Danger of explosion if battery is in-
correctly 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 fire or chemical burn hazard if mis-
treated. 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 charg-
ing, multilati on 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 re-
placed 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 are as 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 re-
placement 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 re-
turned to their original condition. Also check the
area around the repair location to ensure that re-
pair 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 dam-
aged 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.
