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

•Set the radio’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 permanent hearing loss.

•Once you set the volume, do not increase it. Over a period of time, your ears adapts to the volume level, so a level that does not cause discomfort might still damage your hearing.

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

Even though some earphones let you hear some outside sounds when listening at normal volume levels, they still can present a traffic hazard.

Your clock radio might cause TV or radio interference even when it is operating properly. To determine whether your clock radio is causing the interference, turn off your clock radio. If the interference goes away, your clock radio is causing it. Try to eliminate the interference by:

•moving your clock radio away from the receiver

•connecting your clock radio to an outlet that is on a different electrical circuit from the receiver

•contacting your local RadioShack store for help

If you cannot eliminate the interference, the FCC requires that you stop using your clock radio.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
