Charging

Lenovo is not responsible for the performance or safety of products

not manufactured or approved by Lenovo. Use only approved Lenovo

ac adapters and batteries. Adapter shall be installed near the

equipment and shall be easily accessible.

Prevent hearing damage

The 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 the Lenovo Phone complies with

EN 50332-2 Sub clause 7. This speciﬁcation limits the 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.

If the Lenovo Phone came with headphones or earphones in the

package, as a set, the combination of the headphones or earphones

and the Lenovo Phone 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.
