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 higher 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.
