Then adjust the volume control on the left earpiece
until you reach a comfortable listening level.

To protect your hearing, follow these guidelines when you
use this headset.

• Set the volume to the lowest setting before you begin

listening. After you begin listening, adjust the volume
to a comfortable level.

• Do not listen at extremely high volume levels.

Extended high-volume listening can lead to perma-
nent hearing loss.

• Once you set the volume, do not increase it. Over

time, your ears adapt to the volume level, so a vol-
ume level that does not cause discomfort might still
damage your hearing.

Do not wear this headset while operating a motor vehicle
or riding a bicycle. This can create a traffic hazard and
could be illegal in some areas.

To enjoy your RadioShack PRO-100 Communications
Headset for a long time:

• Keep the headset dry. If it gets wet, wipe it dry imme-

diately.

• Use and store the headset only in normal tempera-

ture environments.

• Handle the headset gently and carefully. Don’t drop it.

• Keep the headset away from dust and dirt.

• Wipe the headset with a damp cloth occasionally to

keep it looking new.

Modifying or tampering with the headset’s internal com-
ponents can cause a malfunction and might invalidate its
warranty. If your headset is not performing as it should,
take it to your local RadioShack store for assistance.
