Prevent hearing damage

Your device 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 your device complies with EN 50332-2 Sub 
clause 7. This specification limits the device'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 your device came with headphones or earphones in the package, as a set, the 
combination of the headphones or earphones and the device 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.
