Polyvinyl Chloride (PVC) cable and cord notice

WARNING: Handling the cord on this product or cords associated
with accessories sold with this product will expose you to lead, a
chemical known to the State of California to cause cancer, and birth
defects or other reproductive harm. Wash hands after handling.

Using headphones or earphones

CAUTION:

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.
