• It will automatically activate again when sound is detected.

⚙️ Parameter Tuning

1. Tap the Menu button on the device or remote control to enter the settings menu.

2. Use the VOL+ / VOL- buttons to adjust menu options.

3. To exit the menu, press the remote’s Exit button or wait 5 seconds for the menu to disappear automatically.

🎚️ Sensitivity Adjustment

• During normal operation, press VOL+ / VOL- to adjust sensitivity.
  Range: 0–19

• An adjustable potentiometer on the back of the unit allows line gain adjustment (only effective for line input).

⏰ Clock Adjustment

1. Enter Clock Display Mode (MODE: 9).

2. Use the VOL- button to select position, and VOL+ to change values.

📊 Display Mode Descriptions (MODE Setting)

Select from 14 display modes using the remote or touch interface:

⚙️ Additional Settings

• SPEED: Controls fall speed of floating points and horizontal scroll.
  Range: 0–4 (slow to fast)

• DIMMER: Screen brightness adjustment.
  Levels: 0–4

• GAIN: Manual gain control.
  Range: 0–19

• SMOOTH: Visual smoothing settings.
  0 = None, 1 = Linear smoothing, 2 = Quadratic fitting

• LEARN (Noise Cancellation):
  Press VOL+ to enter learning mode.
  A horizontal line appears — ambient noise during this time will be sampled and filtered out in future displays.
  After ~30 seconds, the process ends, normal display resumes, and gain resets to 0.

• DEMO: Automatic demo mode.
  0 = Off, 1 = On (cycles through display modes automatically)

• MIC: Enable or disable built-in microphone input.
  0 = Off, 1 = On

• AGC (Automatic Gain Control):
  0 = Off, 1 = On
  AGC adjusts input gain dynamically every 5 seconds to maintain ideal display amplitude.

• SLEEP: Automatic sleep mode.
  0 = Off, 1 = Switches to clock display after mute

• FACTORY: Resets all parameters and noise data to factory defaults.
