Chassis Cover Removal and Replacement
Before removing the chassis cover to service or modify the equipment, you must disconnect all power
and modem cords (and remove the main battery in portable computers).
Replace the chassis cover and secure it with the screws before plugging in the power cable and turning
it on.
Avoid contact with the equipment during thunderstorms.
In thunderstorm conditions, make sure that you disconnect your modem from the telephone line or
your TV port from the aerial socket. A lightning strike to nearby telephone lines or an aerial could
damage your modem, TV card or even your whole computer system. Please note that the product
warranty does not apply if damage to your computer is the result of a lightning strike.
Excessive sound pressure from earphones and headphones can cause hearing loss.
Adjustment of the equalizer to other values than the neutral or centre position may increase the
earphones and headphones output voltage and therefore the sound pressure level.
Other influencing factors relevant for the earphones/headphones output and which are specified by
the manufacturer (e.g. operating system, other equalizer software, firmware and drivers) may increase
the earphones and headphones output voltage and therefore the sound pressure level.
