3.2. Charging the Battery

The device is equipped with a 3.7V, 1800mAh rechargeable lithium battery. Before first use, fully charge the device.

1. Connect the provided Type-C USB cable to the charging port on the device.
2. Connect the other end of the cable to a standard USB power adapter (not included) or a computer USB port.
3. The charging indicator on the device will show charging status. A full charge provides approximately 5 days of battery life in standard mode, or up to 30 days in long endurance mode.

3.3. Initial Power On

Press and hold the power button (usually the central 'OK' button) until the LCD screen illuminates. The device will perform a self-test and then display the main measurement interface.

4. Operating Instructions

4.1. Understanding the Display

The LCD display provides real-time radiation data. The main interface typically shows:

• Real-time Dose Rate: Current radiation level (e.g., μSv/h).
• Average Dose Rate: Average radiation level over a period.
• Total Dose: Cumulative radiation dose received.
• Count Rate: Number of radiation particles detected per unit time (CPM/CPS).

Figure 5: Overview of the device's display and key features, including real-time, average, and total dose readings.

Figure 6: The device supports multiple display interfaces, including a simple style and a curve interface for dose rate trends.

4.2. Alarm Functions

The FS5000 features three combined alarm modes: Light, Vibration, and Audible. You can set alarm thresholds for both current dose rate and accumulated dose.

• If the detected radiation dose exceeds the set threshold, the device will automatically trigger the configured alarms.
• The particle counting sound provides an auditory indication of radiation presence, which can be toggled on or off in settings.

Figure 8: The device features a clear particle counting sound and dual alarm indicators for dose and dose rate.

4.3. Adjusting Settings

Navigate through the device's menu using the control buttons to access various settings:

• Threshold: Set alarm values for current dose rate and accumulated dose.
• Data: Access recorded data and historical trends.
• Timed Dose: Configure timed measurement periods.
• Alarm: Enable/disable specific alarm types (light, vibration, sound).
• Language: Switch between multiple language options.
• Time: Adjust calendar clock settings.
• Backlight: Adjust screen backlight time and brightness.
• Mode: Switch between different display styles (simple/compact).

5. Maintenance

5.1. Cleaning

Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the casing or screen.

5.2. Storage

Store the device in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, ensure the battery is partially charged (around 50%) to prolong its lifespan.

5.3. Battery Care

To maximize battery life, avoid fully discharging the battery frequently. Recharge the device when the battery indicator is low.
