16. Noise lock squelch control + voice code navigation lock squelch control

1. (built in voice control matrix system) support multiple full open modes, greatly improve the ability to prevent howling, and make the human voice more fidelity without adding feedback device

2. (any two-way can switch to true diversity reception mode) so that the microphones distributed at the far end and the chairman microphone have better stable performance

3. (with Chairman priority function) make the meeting better controlled

4. The unit adopts OLED HD color display

5. The unit uses 2000mha lithium battery, which can work continuously for more than 10 hours and stand by for more than 20 hours

6. Exquisite short rod design, the line of sight pickup distance can reach 80cm, clear and clear

7. Multiple machines can be connected in series to realize the multi person full open mode. A chairman unit can prohibit all representative units from automatically recovering after 6 seconds

8. Equipped with automatic frequency scanning function, the host radar scans the surrounding radio waves and automatically selects a frequency without interference
