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 Start your volume control at a low setting Slowly increase the sound until you can hear it comfortably and clearly without distortion Once you have established a comfortable level Set the dial and leave it there Taking a minute to do this now will help to prevent hearing loss or damage in the future After all we want you listening for a lifetime Decibel Level Example 30 Quiet library soft whispers 40 Living room refrigerator bedroom away from traffic 50 Light traffic normal conversation quiet office 60 Air conditioner at 20 feet sewing machine 70 Vacuum cleaner hair dryer noisy restaurant 80 City traffic garbage disposals alarm clock at two feet The following noises can be dangerous under constant exposure 90 Subway motorcycle truck traffic lawn mower 100 Garbage truck chain saw pneumatic drill 120 Rock concert in front of speakers thunderclap 140 Gunshot blast jet plane 180 Rocket launching pad STI LLA JER WT ade 405 624 8510 LIMITED WARRANTY Stillwater Designs warrants this product to be free from defects in material and workmanship under normal use and conditions for a period of three 3 years from date of origi
