electrical code for installation requirements in your area.
WARNING: Excessive sound pressure from earphones
or headphones can cause hearing damage or loss.
Adjustment of the volume control as well as the equalizer
to settings other than the center position may increase the
earphones or headphones output voltage, and therefore the
sound pressure level.
The use of factors influencing the earphones or
headphones output other than those specified by the
manufacturer (e.g. operating system, equalizer software,
firmware, driver, etc.) may increase the earphones or
headphones output voltage and therefore the sound
pressure level.
The use of earphones or headphones other than those
specified by the manufacturer may lead to heightened
sound pressure level.
