The Safety of Your Ears is in Your Hands
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 affecting 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.
ESTABLISH A SAFE LEVEL:
Set 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 sound level, set the dial and leave it there.
BE SURE TO OBSERVE THE FOLLOWING GUIDELINES:
Do not turn up the volume so high that you can’t hear what’s around you.
Use caution or temporarily discontinue use in potentially hazardous situations.
Do not use headphones while operating a motorized vehicle; the use of headphones may create a traffic hazard and is illegal in many areas.
