Additional Safety Information; Rack Shelf Safety Information - Lenovo ThinkStation S20 Safety And Warranty Manual

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) 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.
