PROFESSIONAL TWO-WAY RADIOPT4200 FM PORTABLE RADIO SERVICE MANUAL V060802 PT4200 SERVICE MANUAL DANGEROUS! Do not connect the AC power or DC power over 8.6V with any connector or terminals of the radio. Otherwise it will cause fire or 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 bigger than 20 dBm (100mW). Do not turn on the power before the antenna or load connection is completed. If the antenna has been damaged, do not use the radio. Damaged antenna may cause lightly burning on skin. Though the radio is waterproof, it's better avoid putting it in rain or snow, or any other liquid to ensure its life and performance.
