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. VocoPro and the Electronic
Industries Association's Consumer Electronics Group want you to get the most out of your equipment by playing it at a
safe level. One that lets the sound come through loud and clear without annoying blaring or distortion and, most
importantly, without affecting your sensitive hearing.

Sound can be deceiving. Over time your hearing 'comfort level' adapts to a higher volume 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:

• Start your volume control at a low setting.

• Slowly increase the sound until you can hear it comfortably and clearly, and without
 distortion.

Once you have established a comfortable sound level:

• Set the dial and leave it there.

• Pay attention to the different levels in various recordings.

Taking a minute to do this now will help to prevent hearing damage or loss in the future. After all, we want you listening for
a lifetime.

Used wisely, your new sound equipment will provide a lifetime of fun and enjoyment. Since hearing damage from loud
noise is often undetectable until it is too late, this manufacturer and the Electronic Industries Association's Consumer
Electronics Group recommend you avoid prolonged exposure to excessive noise. This list of sound levels is included for
your protection.

Some common decibel ranges:

Level

30
40
50
60
70
80

Example

Quiet library, Soft whispers
Living room, Refrigerator, Bedroom away from traffic
Light traffic, Normal Conversation
Air Conditioner at 20 ft., Sewing machine
Vacuum cleaner, Hair dryer, Noisy Restaurant
Average city traffic, Garbage disposals, Alarm clock at 2 ft.

The following noises can be dangerous under constant exposure:

Level

90
100
120
140
180

Example

Subway, Motorcycle, Truck traffic, Lawn Mower
Garbage truck, Chainsaw, Pneumatics drill
Rock band concert in front of speakers
Gunshot blast, Jet plane
Rocket launching pad
