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.

2006+A11:2009:+A1:2010+A12:2011, it is mandatory to perform audio tests for EN50332.

This device has been tested to comply with the Sound Pressure Level requirement laid down

in the applicable EN 50332-1 and/or EN 50332-2 standards. Permanent hearing loss may

occur if earphones or headphones are used at high volume for prolonged periods of time.
