Caution About High Volume Usage

Warning: Exposure to loud noise from any source for extended periods of 
time may temporarily or permanently affect your hearing. The louder the 
volume sound level, the less time is required before your hearing could be 
affected. Hearing damage from loud noise is sometimes undetectable at first 
and can have a cumulative effect. To protect your hearing:
• Start your volume control at a low setting and use as low a volume as 

possible.

• Limit the amount of time you use headsets or headphones at high volume.
• Where possible, use your headset in a quiet environment with low 

background noise.

• Avoid turning up the volume to block out noisy surroundings.
• Turn the volume down if you can’t hear people speaking near you.
If you experience hearing discomfort, including the sensation of pressure or 
fullness in your ears, ringing in your ears, or muffled speech, you should stop
