USER SAFETY GUIDE
ESTABLISH A SAFE SOUND LEVEL
Over time hearing will adapt to continuous exposure to loud sounds and what can seem normal, may in fact be harmful.
To guard against this BEFORE HEARING ADAPTS, set the volume at a low level.
• Slowly increase the level until sound can be heard comfortably and clearly, without distortion.
• Hearing damage is cumulative and is irreversible.
• Ringing or discomfort in the ears indicates the volume is too loud.
Once a comfortable listening level has been established, DO NOT INCREASE THE SOUND LEVEL FURTHER.
The following list of typical sound levels may assist you in recognizing how loud you have set the volume level.
