Product Introduction
This walkie talkie, in conjunction with the base station host, forms a wireless dispatch command system that can achieve intercom function, single call function, group call function, automatic power-saving function, low voltage prompt function, etc
The shell has undergone special anti-static treatment to eliminate the possibility of static electricity accumulation and potential hazards
The shell is made of cushioning rubber material to prevent damage to the machine
Dual mode communication mode, read-write frequency encryption, analog sub audio/digital sub audio
Powered by explosion-proof nickel hydrogen batteries, with longer standby time
Strict explosion-proof standards are required for power, and advanced intrinsic safety limiting circuits are used. Even under the most unfavorable conditions, the power will not exceed 3.5W and pose a danger
High transmission power was achieved at low power supply voltage, achieving miniaturization of the entire machine
Application Scenario:
Can be used in explosive gas hazardous areas in Zone I and Zone II
