Chapter 1. Important safety information

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. If different
