Listening Safely

To protect your hearing, follow these guide- lines when you use an earphone.

Set the volume to the lowest setting before you begin listening. After you begin listening, adjust the volume to a comfort- able 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 time, your ears adapt to the vol- ume level, so a volume level that does not cause discomfort might still damage your hearing.

MAINTENANCE

Your Radio Shack AM/FM Portable Radio is an example of superior design and craftsman- ship. The following suggestions will help you care for the radio so you can use it for years.

Keep the radio dry. If it gets wet, immedi- ately wipe it dry. Liquids might contain minerals that can corrode the electronic circuits.

Use and store the radio only in normal temperature environments. Temperature extremes can shorten the life of electronic devices, damage batteries and distort or melt plastic parts.

Handle the radio gently and carefully. Dropping it can damage its circuit board and can cause the radio to work improp- erly.

Keep the radio away from dust and dirt, which can cause premature wear of parts.

Wipe the radio with a damp cloth occa- sionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the radio.

Modifying or tampering with the radio’s inter- nal components can cause a malfunction and might invalidate the radio’s warranty and void your FCC authorization to operate it. If your radio is not performing as it should, take it to your local Radio Shack store for assistance.
