- SET Button [SET]: Click to select menu items. Pay attention to the flashing status of screen characters.
- Up Arrow Button [▲]: Click to increase a value or change a state.
- Down Arrow Button [▼]: Click to decrease a value or change a state.
- Temperature Setting: When 'SV' (or a temperature value like '65°C') is flashing, use the Up/Down arrow buttons to adjust the target heating temperature.
- Unit Switch: When '°C' is flashing, click the arrow button to switch between Celsius (°C) and Fahrenheit (°F).
- LED Status: When 'SUNLU' (or similar indicator) is flashing, click the arrow button to change the LED running light status (e.g., flow LED, always on, or off).
- Filament Type Setting: When 'PETG' (or similar filament type indicator) is flashing, click the arrow button to set the filament type and use recommended temperature parameters.
- Time Setting: When 'Time: 04:53:52' is flashing, click the arrow button to set the drying time (maximum 99 hours).
- Humidity Setting (MO2 Mode): When 'RH 48%' (or similar humidity value) is flashing, click the arrow button to preset the automatic startup humidity value for MO2 mode (maximum 50%, minimum 30%).
- Mode Selection: When 'MO' is flashing, click the arrow button to switch between MO1 and MO2 modes.
Mode Descriptions:
- MO1: Time control mode (device shuts down after the countdown ends).
- MO2: Humidity control mode (after the countdown ends, if humidity rises slowly to 50% or the user-set humidity value, it will automatically start heating until the humidity drops to 25%).
Note: If the humidity does not decrease to the target value, check if the top cover is properly closed or increase the set heating temperature by 5 °C.

Tips to Prevent Consumables from Getting Wet Again
To prevent filaments from becoming damp again after drying:
- Users can place desiccant in the desiccant tank.
- Use the silicone plug provided in the accessory bag to block any unnecessary outlet holes.
Note: Do not block the outlet holes while the machine is running, as this can prevent internal moisture from being discharged.
