Important Headset Safety Information

When you plug in your headset, lower the volume of the headset speaker before you put the headset on. If

you remember to lower the volume before you take the headset off, the volume will start lower when you

plug in your headset again.

Be aware of your surroundings. When you use your headset, it may block out important external sounds,

particularly in emergencies or in noisy environments. Don't use the headset while driving. Don't leave your

headset or headset cables in an area where people or pets can trip over them. Always supervise children who

are near your headset or headset cables.
