Important Headset Safety Information
High Sound Pressure—Avoid listening to high volume levels for long periods to prevent
possible hearing damage.
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.
