- Connect the scanner directly to your computer using the provided USB cable.
- The scanner will automatically switch to wired mode and can be used immediately.
- In wired mode, the scanner also charges its internal battery.
Operating Modes
1. Instant Upload Mode:
In this mode, barcode data is transmitted to your computer immediately after each successful scan. This is the default operating mode and is suitable for real-time inventory management or point-of-sale applications.

Figure 6: The scanner can read barcodes directly from digital screens, such as a phone display. Example barcode: 6901234567892.
2. Offline Storage Mode:
When operating outside the wireless transmission range, the scanner can store up to 100,000 barcodes in its internal memory. To activate this mode, scan the appropriate barcode from the user manual (refer to the manual for specific programming barcodes). Once scanning is complete, return to the wireless range and upload the stored data to your device.
Scanning Techniques:
- Trigger Mode: Press the trigger button to initiate each scan.
- Automatic Mode: The scanner will continuously scan without requiring a button press, ideal for high-volume scanning. To switch modes, scan the corresponding programming barcode in your user manual.
