- Charging:
- USB Charging: Pull out the waterproof USB plug on the right side and insert the Type-C USB cable.
- Cradle Charging: A separate cradle can charge one battery and one terminal simultaneously. The left indicator light shows battery charging status (red for charging, green for full). The right light indicates power on (green for on, off for off).
- Low Battery Warning: Charge the device when battery power is less than 20% to prevent over-consumption. If the battery is in an over-consumption state, charge for 20-30 minutes to restore normal charging status.

- Troubleshooting Scanning: If no data is received despite the scan light being on, check "keyboard output" in scan settings. If checked, reset the scan demo twice (OFF-ON). If the device cannot scan, check if scan buttons work, if the scan engine supports the barcode, if the scanning lens is clear, and reset scan settings.
- NFC Function (Optional):
- Locate and open the "NFC" app.
- Read cards by placing them near the NFC reading area.
- System Updates (OTA):
- Go to "Settings" > "About phone" > "System update."
