Portable Device Battery Safety

WARNING: The system battery can only be replaced by an authorized service provider. Using an incompatible battery may increase the risk of fire or explosion.

Do not expose (store or place) your computer or battery pack next to a heat source such as a radiator, fireplace, stove, electric heater, or other heat-generating appliance or otherwise expose it to temperatures in excess of 65ºC (149ºF). When heated to excessive temperatures, battery cells could vent or explode, posing risk of fire.

Earphone and Headphone Safety

WARNING: Excessive sound pressure from earphones or headphones can cause hearing damage or loss. Adjustment of the volume control as well as the equalizer to settings other than the center position may increase the earphones or headphones output voltage, and therefore the sound pressure level.

The use of factors influencing the earphones or head- phones output other than those specified by the manufac- turer (e.g. operating system, equalizer software, firmware, driver) may increase the earphones or headphones output voltage and therefore the sound pressure level.

The use of earphones or headphones other than those specified by the manufacturer may lead to heightened sound pressure level.
