2.2 Headphones
CAUTION
Impaired hearing due to excessive sound pressure
The setting of the volume and the equalizer can increase the sound pressure in the
headphones. Other factors not mentioned by the manufacturer can also influence the
sound pressure, for example, the operating system, equalizer software, firmware and
driver.
Excessive sound pressure from headphones can result in impaired hearing or even loss of
hearing.
Set the volume control and equalizer to the lowest value before you put on the
headphones. Keep checking the volume control setting. Only use headphones and
software approved by the manufacturer.
