1. Product Features
JWAT943 telephone adopts stainless steel wire drawing panel and shell, which has high mechanical strength and strong wear resistance and corrosion resistance. The circuit board adopts the concept of integrated design, and integrates the basic call circuit and noise removal circuit in a machine. And preferably foreign well-known brand components. After high and low temperature testing, procurement and production, the circuit undergoes strict protection treatment, so that the environmental adaptability of the whole machine is further improved.
