The liquid crystal display (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.
Note: For products with mercury-containing fluorescent lamps (for example, non-LED), the fluorescent lamp
in the liquid crystal display (LCD) contains mercury; dispose of according to local, state, or federal laws.
Use earphones, headphones, or a headset
• If your computer has both a headphone connector and an audio line-out connector, always use the
headphone connector for earphones, headphones, or a headset. However, the headphone connector
does not support the microphone of the headset.
• If your computer has both a headset connector and an audio line-out connector, always use the headset
connector for earphones, headphones, or a headset.
Excessive sound pressure from earphones and headphones can cause hearing loss. Adjustment of the
equalizer to maximum increases the earphone and headphone output voltage and the sound pressure level.
Therefore, to protect your hearing, adjust the equalizer to an appropriate level.
Excessive use of headphones or earphones for a long period of time at high volume can be dangerous if the
output of the headphone 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) or 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, the combination of
the headphones or earphones and the computer already complies with the specifications of EN 50332-1. If
different headphones or earphones are used, ensure that they comply with EN 50332-1 (Clause 6.5
Limitation Values). Using headphones that do not comply with EN 50332-1 can be dangerous due to
excessive sound pressure levels.
