Chapter 1. Important safety information The power cord must be disconnected from the wall outlet or receptacle before installing all other electrical cables connected to the Lenovo computer. The power cord may be reconnected to the wall outlet or receptacle only after all other electrical cables have been connected to the computer. „ Liquid crystal display (LCD) notice For products with mercury-containing fluorescent lamps: (non-LED LCD) The fluorescent lamp in the liquid crystal display contains mercury; dispose according to local, state, or federal laws. 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. „ Using headphones or earphones If your computer has both a headphone connector and an audio-out connector, always use the headphone connector for headphones (also called a headset) or earphones. Excessive sound pressure from earphones and headphones can cause hearing loss. Adjustment of the equalizer to maximum increases the earphones and headphones output voltage and therefore the sound pressure level. Excessive use of headphones or earphones for a long period of time at high volume can be dangerous if the output of the headphones or earphone connectors do not comply with specifications of EN 50332-2. The headphone output connector of your computer complies with EN 50332-2 Sub clause 7. This specification limits the computer's maximum wide band true RMS output voltage to 150 mV. To help protect against hearing loss, ensure that the headphones or earphones you use also comply with EN 50332-2 (Clause 7 limits) for a wide band characteristic voltage of 75 mV. Using headphones that do not comply with EN 50332-2 can be dangerous due to excessive sound pressure levels. If your Lenovo computer came with headphones or earphones in the package, as a set, combination of the headphones or earphones and the computer already complies with the specifications of EN 50332-1.
