Scanning Barcodes
To scan a barcode, point the scanner's lens at the barcode and press the scan button. The scanner will emit a light beam to read the code. A successful scan is typically indicated by a vibration (if enabled) and/or an audible beep.

The scanner can read a wide variety of barcode types, including:
- 1D Barcodes: UPC, EAN, Code128, Code39, Code 39 Full ASCII, Coda bar, Industrial 2/5, Interleaved 2/5, Code 93, MSI, Code11, ISBN, ISSN, GS1, Databar, Code32.
- 2D Barcodes: QR Code, Data Matrix, PDF417, Micro PDF417, MaxiCode, Aztec.
Upload Modes
- Instant Upload Mode: In this mode, scanned barcodes are immediately transmitted to the connected device. This is the default mode and is suitable for real-time data entry.
- Memory Mode: If the scanner is out of range or not connected to a host device, it can store scanned barcodes in its internal 16MB memory. This memory can hold up to 50,000 barcodes. To upload stored data, reconnect the scanner to your device and scan the "Upload Data" barcode (refer to the full manual for specific barcodes).
Vibration Function
The scanner features a vibration function to provide tactile feedback upon a successful scan. This is particularly useful in noisy environments where audio cues might be missed, or in quiet environments where an audible beep is undesirable. You can typically enable or disable this function by scanning specific configuration barcodes (refer to the full manual).

Maintenance
Cleaning
Wipe the scanner's exterior with a soft, dry, lint-free cloth. For stubborn dirt, slightly dampen the cloth with water. Do not use harsh chemicals, abrasive cleaners, or solvents, as these can damage the device.
Storage
Store the scanner in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period, ensure the battery is partially charged (around 50%) to prolong its lifespan.
Battery Care
The scanner is equipped with a 400mAh rechargeable battery. To maximize battery life:
- Avoid fully discharging the battery frequently.
- Avoid leaving the scanner connected to power for prolonged periods after it's fully charged.
- Charge the scanner using only the provided USB cable and a compatible 5V/1A (max 5V/1.2A) power source.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Scanner not connecting via Bluetooth. | Scanner not in pairing mode; device Bluetooth off; interference. | Ensure scanner is in Bluetooth pairing mode (scan appropriate barcode). Turn Bluetooth off/on on host device. Move closer to host device. |
| Scanner not reading barcodes. | Barcode damaged/unreadable; insufficient light; scanner settings. | Ensure barcode is clear and well-lit. Try scanning a different, known-good barcode. Check scanner's configuration settings (refer to full manual). |
| Scanned data not appearing on device. | Not connected; incorrect upload mode; application issue. | Verify connection (Bluetooth, 2.4G, USB). Ensure scanner is in instant upload mode. Check if the receiving application is active and ready for input. |
| Short battery life. | Battery not fully charged; aging battery; high usage. | Ensure full charge before use. Reduce continuous scanning if possible. If battery life significantly degrades, contact support. |
