regulations.
The available scientific evidence does not show that any health problems are associated
with using low power wireless devices. There is no proof, however, that these low power
wireless devices are absolutely safe. Low power Wireless devices emit low levels of radio
frequency energy (RF) in the microwave range while being used. Whereas high levels of RF
can produce health effects (by heating tissue), exposure of low-level RF that does not
produce heating effects causes no known adverse health effects. Many studies of low-level
RF exposures have not found any biological effects. Some studies have suggested that
some biological effects might occur, but such findings have not been confirmed by additional
research. These models have been tested and found to comply with FCC/IC radiation
exposure limits set forth for an uncontrolled environment and meet the FCC radio frequency
(RF) Exposure Guidelines in Supplement C to OET65 and RSS-102 of the IC radio
frequency (RF) Exposure rules.
Listening for a Lifetime
Selecting fine audio equipment such as the unit you’ve just purchased is only the start of
your musical enjoyment. Now it’s time to consider how you can maximize the fun and
excitement your equipment offers. This manufacturer, the Consumer Electronics Association
(CEA)® and the American Speech-Language-Hearing Association (ASHA) want you to get
the most out of your equipment by playing it at a safe level; a level that lets the sound come
through clearly without annoying blaring or distortion and, most importantly, without
damaging your sensitive hearing.
Sound can be deceiving. Over time your hearing “comfort level” adapts to higher volumes of
sound. So what sounds “normal” can actually be loud and harmful to your hearing. Guard
against this by setting your equipment at a safe level BEFORE your hearing adapts.
TO ESTABLISH A SAFE LEVEL:
Set your volume control to the lowest level where you can hear the music comfortably
and clearly. Prolonged exposure to anything over 85 decibels can cause gradual
hearing loss.
Once you have established a sound level where you can hear the audio comfortably,
clearly and without distortion, set the dial and leave it there.
See if your music player has a volume limiter that allows you to set a safe listening level
by establishing a maximum volume level on your player. This is a great solution for
parents to ensure their children listen at a safe level.
Limit listening time to give your hearing “quiet breaks.”
BE SURE TO OBSERVE THE FOLLOWING GUIDELINES WHEN WEARING YOUR
HEADPHONES OR EARBUDS:
Do not turn up the volume so high that you can’t hear sounds around you.
Do not use headphones or earbuds while operating a motorized vehicle; it may create a
traffic hazard and is illegal in many areas.
Used wisely, your new sound equipment will provide years of fun and enjoyment.
Since hearing damage from loud noise is often undetectable until it is too late, this
manufacturer, CEA and ASHA recommend that you avoid prolonged exposure to excessive
noise. The following list of sound levels is included for your information so that you can better
protect your hearing.
DECIBEL LEVEL EXAMPLES:
30 Whisper
40 Quiet room
50 Moderate rainfall
60 Normal conversation
70 Busy traffic, vacuum cleaner
80 Alarm clock
CONSTANT EXPOSURE TO THESE NOISES CAN BE DANGEROUS:
90 Lawn mower, motorcycle
100 Chain saw
110 Rock concert
120 Jet plane takeoff
130 Jackhammer
140 Firecrackers
