Quick Reference Guide
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.
