(especially aggressive) on the Transceiver;
•It if forbidden to use the Transceiver during storms;
•Don't open the Transceiver. It contains the radio elements, which have the high sensitivity to the
static electricity. This document contains all the necessary information about the internal design
to satisfy the curiosity of Users. To repair the Transceiver ask the manufacturer;
•Always unplug the Transceiver's antenna, if you don't control it or if there appear a danger of
atmospheric electricity damage;
•Save the Transceiver, cables and wires from the influence of the magnetic pickups (emergency
states), out controlled currents and voltages and the domestic animals;
