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, 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.

Additional safety information

Plastic bags can be dangerous. Keep plastic bags away from babies and children to avoid danger of

suffocation.

Your Additional Responsibilities
