Listening Safely
To protect your hearing, follow these guidelines when
you use the headset.
• Set the phone’s 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.
Traffic Safety
Do not use the headset with your cellular telephone when
operating a motor vehicle or riding a bicycle in or near
traffic. Doing so can create a traffic hazard and could be
illegal in some areas.
If you use the headset with your cellular telephone while
riding a bicycle, be very careful. Do not listen to a continu-
ous broadcast. Even though some earphones/headphones
let you hear some outside sounds when listening at normal
volume levels, they still can present a traffic hazard.
CARE AND MAINTENANCE
Your RadioShack HS-1903 Earpiece with Boom Micro-
phone, Noise Cancellation, Volume Control and Micro-
phone Mute is an example of superior design and
craftsmanship. The following suggestions will help you
care for your headset so you can enjoy it for years.
• Keep the headset dry. If it gets wet, wipe it dry imme-
diately.
• Handle the headset gently and carefully. Don’t drop
it.
• Use and store the headset only in normal tempera-
ture environments.
• 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
your headset’s warranty. If your headset is not perform-
ing as it should, take it to your local RadioShack store for
assistance.
