3. Setup and Operation
3.1 Device Components

The data logger features a USB connector, a start/stop button, and LED indicators for status updates. The specific model shown is for 7 days of recording.
3.2 Starting the Data Logger
- To activate the data logger, press and hold the START/STOP button for approximately 5 seconds.
- Upon successful activation, the green LED indicator will flash 3 times. This confirms the device has started recording.
- There is a default power-on delay time of 10 minutes. During this delay, the yellow LED light will flash every 30 seconds. This indicates that the device is preparing to record but has not yet started logging temperature data.
- After the 10-minute delay, the device will begin active temperature logging.

3.3 LED Indicator Status
The LED indicators provide visual feedback on the device's status:
- Green LED flashes 3 times: Device successfully started.
- Yellow LED flashes every 30 seconds: Indicates the 10-minute start delay is active.
- Green LED flashes (during logging): Temperature is within the configured alarm range.
- Red LED flashes (during logging): Temperature has exceeded the default alarm range.

3.4 Stopping the Data Logger
The data logger is designed for single use. It will automatically stop recording once its specified duration (e.g., 7 days for this model) is complete, or when it is connected to a computer for data retrieval. Once stopped and data is accessed, the device cannot be restarted for a new recording cycle.
4. Data Retrieval and Reporting
After the monitoring period is complete, retrieve the recorded data by following these steps:
- Locate the USB connector on the data logger.
- Plug the data logger directly into an available USB port on your computer.
- The device will automatically generate PDF and CSV reports. No special software installation is required.
- The reports will typically appear as a removable drive on your computer, containing the PDF and CSV files. Save these files to your computer for analysis.

The reports include detailed temperature graphs, summary statistics, and a calibration certificate, providing comprehensive data for cold chain analysis.

6. Maintenance
The Freshliance Fresh Tag 1 is a disposable device and requires minimal maintenance. It is designed for single use and cannot be reset or reused after data retrieval.
- Storage: Store unused loggers in their original packaging in a cool, dry place, away from direct sunlight and extreme temperatures, to preserve battery life and accuracy. The product has a shelf life of 3 years.
- Disposal: Dispose of the used data logger according to local regulations for electronic waste.

7. Troubleshooting
- Device Not Starting: Ensure you press and hold the START/STOP button for a full 5 seconds until the green LED flashes 3 times. If the battery is depleted (unlikely for a new device within shelf life), the device may not start.
- No Data After Starting: Remember the default 10-minute delay after pressing the start button. The yellow LED will flash during this period. Actual temperature logging begins after this delay.
- Cannot Generate Report: Ensure the data logger is fully inserted into a functional USB port. Try a different USB port or computer. The device is single-use; if it has been previously connected to a computer and stopped, it cannot generate a new report.
- LED Indicators Not Functioning: If the LEDs do not respond after pressing the button, the device may be faulty or the battery may be completely drained.
