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.
