4. Getting Started
4.1. Charging the Device
Before first use, fully charge the GC-03 using the provided USB Type-C cable and a standard 5V/1A USB power adapter (not included). The charging indicator on the screen will show the battery status.
4.2. Powering On/Off
- To Power On: Press and hold the power button (usually located on the side or top) for a few seconds until the screen illuminates.
- To Power Off: Press and hold the power button again until the device shuts down.
5. Operating Instructions
5.1. Navigating the Interface
The GC-03 features an intuitive rotary knob for easy navigation through menus and settings. Rotate the knob to scroll and press it to select options.

5.3. Nuclear Radiation Detection
The GC-03 utilizes an energy compensation GM tube for precise detection of ionizing radiation (Gamma rays, X-rays, and Hard Beta rays).
- Hold the device in the area you wish to monitor.
- Observe the real-time radiation values on the screen.
- The device will alert you if radiation levels exceed preset thresholds.

5.4. Electromagnetic Field (EMF) Detection
The device measures both electric and magnetic fields. Note that magnetic field values are displayed only when the magnetic field is changing or being cut; static magnetic fields (e.g., from permanent magnets) may not show a reading.
- Select the appropriate EMF detection mode.
- Move the device around the area or object to be measured.
- Readings for electric field (V/m) and magnetic field (µT or mG) will be displayed.

5.5. Alarm Settings
You can customize alarm thresholds for nuclear radiation. When these thresholds are exceeded, the device will provide visual, audible, and vibration alerts. For electric and magnetic field alarms, the over-limit status will be displayed on the interface, but there will be no vibration, sound, or light prompts.
5.6. Day & Night Themes
Adjust the display theme in the settings menu to switch between light and dark modes for optimal visibility in different lighting conditions.
6. Maintenance
6.1. Cleaning
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the casing or screen.
6.2. Battery Care
The GC-03 uses a 1500mAh Lithium Polymer battery. To prolong battery life, avoid extreme temperatures and store the device with a partial charge if not used for extended periods.
6.3. Firmware Upgrade
Periodically check the official FNIRSI website for available firmware updates. Follow the instructions provided with the update package to ensure proper installation.
7. Troubleshooting
- Device does not power on: Ensure the battery is charged. Connect the device to a power source using the Type-C cable and try again.
- Inaccurate readings: Ensure the device is used in an environment free from strong electromagnetic interference. Calibrate if necessary (refer to advanced settings in the device menu).
- No magnetic field reading: Magnetic field values are typically displayed only when the magnetic field is changing or being cut. Static magnetic fields will not register a reading. This is normal operation.
- Screen is dim or unreadable: Adjust the screen brightness in the settings menu or switch between Day/Night themes.
