SAFETY PRECAUTIONS

Four types of messages are used in this manual to bring important information to your
attention. Each of these messages will be italicized and identified as shown below.

DANGER: “Danger” indicates the existence of a hazard that could result in death or

serious bodily injury, if the safety instruction is not observed.

WARNING: “Warning” indicates the existence of a hazard that could result in bodily

injury, if the safety instruction is not observed.

CAUTION:

“Caution” indicates the existence of a hazard that could result in property

damage, if the safety instruction is not observed.

NOTE:

“Note” contains general information that relates to your safe maintenance

service.

Improper repair of the computer may result in safety hazards. Toshiba requires service
technicians and authorized dealers or service providers to ensure the following safety
precautions are adhered to strictly.

Be sure to fasten screws securely with the right screwdriver. If a screw is not fully

fastened, it could come loose, creating a danger of a short circuit, which could cause
overheating, smoke or fire.

If you replace the battery pack or RTC battery, be sure to use only the same model

battery or an equivalent battery recommended by Toshiba. Installation of the wrong
battery can cause the battery to explode.
