Plastic bag notice 

 DANGER 

Plastic bags can be dangerous. Keep plastic bags away from babies and 

children to avoid danger of suffocation. 

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.
