To avoid hearing damage, limit the time you use
earphones at high volume and set the volume to a
safe level. The louder the volume, the shorter the safe
listening time is.
Danger
To prevent accidents and damage to ears:
• Listen at reasonable volumes for reasonable periods
of time.
• Be careful not to adjust the volume continuously upwards
as your hearing adapts.
• Do not turn up the volume so high that you can’t hear
what’s around you.
