Dangerous!
Do not connect the AC power or DC power over 8.6V with
any connector or terminal of the radio. Otherwise it will cause
fire, electric shock or damage to the radio.
Warning!
Do not reverse power connection.
It may cause harm to the radio if signal input on the antenna
connector is larger than 20 dBm (100mW).
Do not turn on the radio before the antenna or load
connection is completed.
If the antenna has been damaged, do not use the radio.
Damaged antenna may cause light burning on skin.
Though the radio is waterproof, it's better to avoid putting it
in rain or snow, or any other liquid to ensure its life and
performance.
