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

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.
If Lenovo Phone came with headphones or earphones in the 
package, as a set, the combination of the headphones or earphones 
and 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.
