Important Safety Information
Avoiding hearing damage
Permanent hearing loss may occur if you use your Headset at a high volume. Set the volume to a
safe level. You can adapt over time to a higher volume of sound that may sound normal but can be
damaging to your hearing.
If you experience ringing in your ears or muffled speech, stop listening and have your hearing checked.
The louder the volume, the less time is required before your hearing could be affected. Hearing experts
suggest that to protect your hearing:
• Limit the amount of time you use Headset at high volume.
• Avoid turning up the volume to block out noisy surroundings.
• Turn the volume down if you can’t hear people speaking near you.
Please refer to your handset user guide for more information on how to adjust listening levels on
your handset.
Using headsets safely
Use of Headset to listen to music while operating a vehicle is not recommended and is illegal in
some areas. Be careful and attentive while driving. Stop using this device if you find it disruptive or
distracting while operating any type of vehicle or performing any other activity that requires your
full attention.
