RECYCLING: Your battery used in the headset must be recycled or disposed of properly. Contact your local recycling center for proper disposal of your headset battery.

To protect your hearing, some hearing experts suggest you:

Set the volume control in a low position before putting your headset on your ear and use as low volume as possible
Avoid turning up the volume to block out noisy surroundings. Whenever possible, use your headset in a quiet environment with low background noise
Limit the amount of time you use headsets at high volume levels
Turn the volume down if the sound from the headset prevents you from hearing people speaking near you

Exposure to high volume sound levels or excessive sound pressure may cause temporary or permanent damage to your hearing. Although there is no single volume setting that is ap- propriate for everyone, you should always use your headset with the volume set at moderate levels and avoid prolonged exposure to high volume sound levels

The louder the volume, the less time is required before your hearing could be affected. You may experience different sound levels when using your headset with different devices. The device you use and its settings affect the level of sound you hear. If you experience hearing discomfort, you should stop listening to the device through your headset and have your hearing checked by your doctor
