2. Battery Activation: The device comes with a pre-installed CR2450 battery. Ensure any protective tabs are removed if present.
3. Software Installation (Optional for Advanced Configuration): While basic data retrieval does not require software, for advanced settings such as delayed start, logging intervals, temperature units, time zones, and alarm ranges, download and install the Frigga Data Software from the official Frigga website. The software is compatible with Windows and Mac OS.
4. Device Configuration: Connect the data logger to your computer via the USB port. Use the Frigga Data Software to set your desired logging parameters. This includes setting the start delay, logging interval, temperature units (°C/°F), time zone, and temperature alarm thresholds.

5. Operating Instructions

1. Starting a Recording: Press and hold the Start Button until the 'REC' icon appears on the LCD screen, indicating that recording has begun. If a delayed start was configured, the device will begin recording after the set delay period.
2. Monitoring Status: The LCD screen will display the current temperature, recording status (REC), and battery level. The LED indicator will flash to confirm operation or indicate an alarm.
3. Switching Temperature Units: Briefly press the Start Button to toggle between Celsius (°C) and Fahrenheit (°F) on the LCD display.
4. Stopping a Recording: Press and hold the Stop Button until the 'REC' icon disappears from the LCD screen. The recording session is now complete.
5. Alarm Indication: If the temperature exceeds the pre-set alarm thresholds during recording, the LED indicator will flash, and an alarm icon may appear on the LCD screen.

6. Data Export and Analysis

1. Direct Report Generation: After stopping a recording, remove the USB cover and plug the data logger into a USB port on your computer. The device will automatically generate a PDF report and a CSV data file. These files can be accessed directly from the device's storage, which appears as a removable drive.
2. Using Frigga Data Software: For more detailed analysis, charting, and statistical reports, open the Frigga Data Software on your computer. Connect the data logger, and the software will allow you to download the recorded data. You can then export this data to various formats, including Excel and PDF, and generate calibration certificates.

7. Maintenance

• Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or immerse the device in liquids.
• Battery Replacement: The Frigga M2D uses a CR2450 coin cell battery. When the battery indicator shows low power, replace the battery by carefully opening the battery compartment (refer to the device's physical markings for access). Ensure correct polarity.
• Storage: Store the data logger in a cool, dry place away from direct sunlight and extreme temperatures when not in use.

8. Troubleshooting

• Device Not Starting Recording: Ensure the battery is not depleted. Check if the device was properly configured using the Frigga Data Software. Press and hold the Start Button firmly until 'REC' appears.
• No Data Exported via USB: Ensure the USB connector is fully inserted into the computer's port. Try a different USB port or computer. Verify that the recording session was stopped correctly.
• LED Alarm Flashing: This indicates that the temperature has gone outside the pre-set alarm thresholds. Review your recorded data to identify the exact time and duration of the excursion.
• Software Issues: If experiencing problems with the Frigga Data Software, ensure you have the latest version installed from the official website. Refer to the software's help documentation or contact Frigga technical support.
