Notice:
The green light is on when VSWR is less than 1.5, the yellow light is on when VSWR is greater than 1.5 and less than 2.5, and the red light is on when VSWR is greater than 2.5. If the VSWR is greater than 2.5 less than 3, the buzzer will alarm intermittently, if the VSWR is greater than 3, (aisanray) will alarm continuously. Battery undervoltage, the buzzer will keep prompting and the yellow indicator light will be on. The buzzer can be turned off with one key
