Important safety and handling information

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.
