Using 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.
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.
