radio's speaker directly against your ear
• Use careful with the earphone maybe possible excessive sound pressure
from 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 first and can
have a cumulative effect.
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
Long transmission
•When the transceiver is used for long transmissions, the radiator and
chassis will become hot.
