The large LCD screen displays key radiation parameters:
- ODODO: Real-time radiation dose rate (µSv/h). This value updates continuously.
- AVG: Average radiation dose rate (µSv/h). This value represents the average over a period of time.
- ACC: Cumulative radiation dose (mSv). This value represents the total accumulated dose since the last reset.
A trend graph is also displayed at the bottom of the screen, visually representing real-time radiation fluctuations.

- L (Sound) Button: Toggles the audible click sound on or off.
- M (Play) Button: Resets the AVG (average) reading.
- R (Light) Button: Toggles the screen backlight on or off.
- L + R (Sound + Light) Buttons: Pressing both L and R buttons simultaneously resets the ACC (cumulative) reading.
