WARNINGS
Be sure to read all warnings and instructions before using your
Metro.fi 2 earphones
.
To avoid damage to your hearing, we recommend that you do not
exceed 50% of the maximum volume on your audio playing device and
that you limit your use to one hour per day.
Always turn music volume down on your listening device before
inserting Metro.fi 2 earphones into your ears. Once earphones are
inserted, gradually increase the volume to a moderate listening level.
Using earphones at high volumes (greater than 85 dB(A)) or for
extended periods of time (more than a one hour period per day) can
permanently damage your ears. Ringing in your ears or other discomfort
can indicate that the music volume is too high.
Hearing damage can be gradual and cumulative. There are
sometimes no obvious warning signs. A hearing test and medical
examination are the only way to accurately diagnose hearing damage.
However, the following symptoms are serious enough to warrant an
appointment with the ear doctor.
• Ringing or buzzing in the ears
• Difficulty in understanding speech.
• Muffling of sounds
LISTEN RESPONSIBLY!
Hearing health is critical to the enjoyment and to the quality of life.
Protect your hearing by listening to your music in a responsible manner
that protects your long term hearing health.
Please review and consider the following Occupational Safety Health
Administration (“OSHA”) guidelines regarding the maximum time
exposure to sound pressure levels before hearing damage may occur.
