Ultimate Ears F1 19 PRO Headphones User Manual

OSHA has established the following noise exposure limits:
YOU SHOULD NEVER BE EXPOSED TO SOUND PRESSURE LEVELS ABOVE 115 dB(A).
For more information visit the OSHA website at www.osha.gov.
The foregoing OSHA exposure levels should be considered maximum
limits. Compliance with the OSHA limits will not provide you with
protection from potential hearing loss. Accordingly, we recommend
never exceeding 50% of the permitted volume on your audio playing
device and limiting your use of headphones to durations of one hour or
less per day. Decibel levels of 85 dB(A) are dangerous to your hearing
and may cause hearing loss.
ƽ Do not use these earphones in any environment where a failure to
hear surrounding sounds could be dangerous. In no way should these
earphones be used while driving a car, biking, walking or operating
machinery.
ƽ Do not submerge or expose the earphones to water (see page 15 for
Earphone Care and Maintenance).
ƽ When using your earphones with an unfamiliar or unstable sound
system (airplane, public access ports, etc…) make sure volume is
low and is kept at a moderate level to prevent “break-in” bursts of
loud sounds. For these environments, we recommend use of the
sound level attenuator to aid in buffering unusually high sound
output
(see page 16 for Sound Level Attenuator)
.
ƽ Keep the Triple.fi earphones away from young children. This product
includes small parts and cables that may create a choking hazard.
