against your ear.

earphones and headphones can cause hearing loss.
Note: Exposure to loud noises from any source for extended periods of time may temporarily or
permanently affect your hearing. The louder the radio's volume, the less time is required before
your hearing could be affected. Hearing damage from loud noise is sometimes undetectable at

Avoid Burns
Antennas
• Do not use any portable radio that has a damaged antenna. If a damaged antenna comes into
contact with the skin when the radio is in use, a minor burn can result.
Batteries (If appropriate)
• When the conductive material such as jewelry, keys or chains touch exposed terminals of the
batteries, may complete an electrical circuit (short circuit the battery) and become hot to cause
bodily injury such as burns. Exercise care in handling any battery, particularly when placing it inside
a pocket, purse or other container with metal objects.
