Important safety and handling information

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.
