Hearing safety
Danger
To avoid hearing damage, limit the time you
use earpieces at high volume and set the
volume to a safe level. The louder the
volume, the shorter the safe listening time is.
Be sure to observe the following
guidelines when using your earpieces.
• 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.
• You should use caution or
temporarily discontinue use in
potentially hazardous situations.
• Excessive sound pressure from
earpieces and earpieces can cause
hearing loss.
• Using earpieces with both ears
covered while driving is not
recommended and may be illegal in
some areas.
• For your safety, avoid distractions
from music or phone calls while in
trac or other potentially dangerous
environments.

of water or diluted mild soap, to clean the
product.
The integrated battery shall not be exposed to
excessive heat such as sunshine, re or the like.
