Head Unit Changes:
1. Fixed a bug where a small black box appeared in the upper-right corner of the TX ERROR prompt page.
2. Fixed a bug where automatic antenna tuning would get stuck in SLPT mode.

Main Unit Changes:
1. Fixed a bug where NFM had no receive (RX) audio.
2. Adjusted the display method of the ALC value:
   - Range: 0-100 
   - Meaning: Indicates MIC or LINE IN audio level. A higher value represents a stronger input signal. 
     When operating in DIGI mode, adjust the LINE IN gain or PC volume to ensure the ALC value remains 
     ≤ 50 for optimal linearity.
