Features

1, can be used in Zone I, II explosive gas dangerous places;

2, the power strictly explosion-proof standard requirements, the use of advanced intrinsically safe limiting circuit, even in the most adverse circumstances, the power will not exceed 3.5W and dangerous;

3, the shell has a special anti-static treatment to eliminate the possibility of electrostatic accumulation may be dangerous, the use of rubber cushioning shell material to absorb the impact energy drop, to prevent damage to the machine;

4, dual-mode communication mode, read and write frequency encryption, analog audio / digital sub-audio;

5, using explosion-proof nickel-metal hydride batteries, standby time longer;

6, in a low power supply voltage to achieve a high launch power, and thus reduce the size of the battery to achieve a miniaturization of the whole machine.
