Audio safety guidelines

If you use your BlackBerry Universal Headset at the maximum sound level over an extended period, hearing impairment might occur.

Research In Motion guarantees compliance with the maximum sound power of its headset as determined by relevant regulatory bodies.

Audio files: The headset can play audio files. When you listen to audio files using a headset, permanent hearing loss might occur if you use the headset at a high volume. Avoid increasing the volume of your headset to block out noisy surroundings. If you experience ringing in your ears or muffled speech, consult a physician to have your hearing checked.
