Important safety and handling information

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 eq ualizer 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 specific ations 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 503 32-1 (Clause 6.5 Limitation Values).

Using headphones that do not comply with EN 50332-1 can be dangerous due

to excessive sound pressure levels.
