DANGER
If the backup battery is incorrectly replaced, there is danger of explosion.
The lithium battery contains lithium and can explode if it is not properly handled
or disposed of.
Replace only with a battery of the same type.
To avoid possible injury or death, do not: (1) throw or immerse the battery into
water, (2) allow it to heat to more than 100 °C (212 °F), or (3) attempt to repair or
disassemble it. Dispose of it as required by local ordinances or regulations and
your company's safety standards.
DANGER
Follow the instruction below when installing or reconfiguring the CDC or Mini
PCI option.
To avoid shock hazard, disconnect all the cables and the ac adapter when you
install the CDC or Mini PCI option or open the covers of the system or attached
devices. Electrical current from power, telephone, and communication cables is
hazardous.
CAUTION:
When you have added or upgraded a CDC or Mini PCI Card or a memory
card, do not use your computer until you have closed the cover. Never use
the computer when the cover is open.
CAUTION:
The fluorescent lamp in the liquid crystal display (LCD) contains mercury.
Do not put it in trash that is disposed of in landfills. Dispose of it as
required by local ordinances or regulations.
The LCD is made of glass, and rough handling or dropping the computer
can cause the LCD to break. If the LCD breaks and the internal fluid gets
into your eyes or on your hands, immediately wash the affected areas with
water for at least 15 minutes; if any symptoms are present after washing,
get medical care.
