Prevent hearing damage
Lenovo Phone has a headphone connector. Always use the headphone
connector for headphones (also called a headset) 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 Lenovo Phone complies with EN 50332-2
Sub clause 7. This specification limits Lenovo Phone'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.
