2	TX1&TX2 Battery Life	The battery level of connected TX devices is displayed in real time, while the battery level of unconnected TX devices is displayed as 0%.
3	MIC1 UV	Real-time level feedback allows you to determine the radio volume by the color of the signal level. The volume is still within the normal range when the signal reaches the yellow zone, but there may be popping or crackling sounds when it reaches the red zone. (In mono mode, only one UV line is displayed.)
4	MIC2 UV	Real-time level feedback allows you to determine the radio volume by the color of the signal level. The volume is still within the normal range when the signal reaches the yellow zone, but there may be popping or crackling sounds when it reaches the red zone. (In mono mode, only one UV line is displayed.)
5	Noise Cancellation Level	Three noise reduction levels are available: weak noise reduction (10dB), medium noise reduction (15dB), and strong noise reduction (20dB). Strong noise reduction is suitable for most outdoor environments, while weak noise reduction is suitable for environments with predominantly low-frequency noise. The noise reduction setting can be adjusted according to the ambient noise level.
6	RX Output Level	It has 6 adjustable levels. The higher the level, the louder the final recording will be, and vice versa. The factory default level is 5.
7	Audio Track Mode	It can output in either mono or stereo mode; the default is mono mode.
8	EQ Adjustment	The preset EQ effects allow users to achieve clearer and more natural sound during recording. EQ presets include: Equal, Deep, and Bright. The default is Equal mode.
9	Reverb Adjustment	The reverb effect makes the recorded sound fuller and more pleasing to the ear in different usage scenarios. Preset reverb levels: Small, Medium, and Large. Reverb is off by default and needs to be enabled manually.
10	MIC Recognization	When activated, the TX1 indicator light will be purple, and the TX2 indicator light will be yellow. Note: When noise cancellation is enabled, the green indicator light for noise cancellation mode will be displayed first; when the indicator light switch is turned off, the indicator lights on the TX will turn off.
