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
