Listening Safely

CARE AND MAINTENANCE

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 l istening can lead to perma­nent hearing loss.

• Once you set the volume, do not increase it. Over
time, your ears adapt to the volume l evel, so a vol­ume 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 creat e a tra ffic hazard and could be
illegal in s ome areas.

If you use the headset with your cellular telephone while
riding a bicycle, be very careful. Do not listen to a continu­ous broadcas t. Even thoug h so me ea rphones /headp hone s
let you hear some outside so unds when listen ing at normal
volume levels, they still can present a traffic hazard.

Your RadioShack HS-1903 Earpiece with Boom Micro­phone, Noise Cancellation, Volume Control and Micro­phone Mute is an example of superior design and
