- General Cleaning: Keep the exterior of the scanner clean by wiping it with a dry or slightly damp cloth.
- Storage: When not in use, store the scanner in a clean, dry environment away from direct sunlight, extreme temperatures, and excessive dust.
- Cable Care: Avoid bending or twisting the USB cable excessively. Do not pull the cable to disconnect the scanner; always grasp the plug.

6. Troubleshooting
If you encounter issues with your OBZ PaymentBox F3 scanner, refer to the following common problems and solutions:
- Scanner not reading barcodes:
Ensure the protective film has been removed from the scan window.
Verify the barcode is within the optimal scanning depth and angle.
Check if the barcode type is supported by the scanner (refer to "Wide Compatibility" in Key Features).
Ensure the USB cable is securely connected to both the scanner and the host device.
- Incorrect characters or symbols appear after scanning (e.g., ':' becomes '+', '=' becomes '^', '@' becomes '"' when scanning URLs):
This issue typically occurs when the scanner's default language setting is English, but the host system's keyboard layout is set to Japanese or another non-English layout. To resolve this, switch your computer's keyboard input language to English (US) before scanning URLs or specific character strings.
- Scanner not powering on:
Confirm the USB cable is firmly connected to a powered USB port on your computer or POS system.
Try connecting the scanner to a different USB port or a different computer to rule out port or device issues.
- Scanner makes a loud startup sound:
The scanner is designed to emit a clear startup sound to confirm connection. While the scan success sound is necessary for operational feedback, the startup sound cannot be adjusted. This is normal operation.
