which are not manufactured or approved by Lenovo.
Prevent hearing damage
Your device 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 your device complies with EN 50332-2 Sub clause
7. This specification limits the device'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 device came with headphones or earphones in the package, as a set, the
combination of the headphones or earphones and the device 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 limits). Using headphones that
do not comply with EN 50332-1 can be dangerous due to excessive sound pressure
levels.
Sound pressure warning statement
For devices that are tested in accordance with EN 60950-1:
2006+A11:2009+A1:2010+A12:2011, it is mandatory to perform audio tests for
EN50332. This device has been tested to comply with the Sound Pressure Level
requirement laid down in the applicable EN 50332-1 and/or EN 50332-2 standards.
Permanent hearing loss may occur if earphones or headphones are used at high
volume for prolonged periods of time.
Warning statement
To prevent possible hearing damage, do not listen at high volume levels for
a long period of time.
Take care when using your device in a motor vehicle or on a bicycle
Always prioritize your safety and the safety of others. Follow the law. Local laws and
regulations might govern how you can use mobile electronic devices, such as your
device, while you drive a motor vehicle or ride a bicycle.
