Scanning Modes
The scanner offers three operational scanning modes, configurable via specific QR codes in the user manual (physical or digital):
- Manual Trigger Mode: Press the scan button to initiate each scan. Scan QR Code for Manual Trigger Mode ($Set#Code^30)
- Auto-sensing Scan Mode: The scanner automatically detects and scans barcodes when presented within its field of view. Scan QR Code for Auto-sensing Scan Mode ($Set#Code^31)
- Continuous Scan Mode: The scanner continuously scans, ideal for high-volume scanning environments. Scan QR Code for Continuous Scan Mode ($Set#Code^32)
Image: Three scenarios demonstrating the scanning modes: a hand holding the scanner to manually scan a phone screen, a worker scanning boxes in auto-sensing mode, and the scanner continuously scanning items on a conveyor belt.
Data Uploading Modes
The scanner supports two methods for uploading scanned data:
- Instant Upload Mode: Barcodes are immediately transmitted to the connected device upon scanning. This is the default mode.
- Storage Mode: Scanned barcodes are stored in the scanner's internal memory (supports over 50,000 barcodes) and can be uploaded later. To activate storage mode, scan the appropriate QR code. To upload stored data, scan the "Data Uploads" QR code. Scan QR Code for Storage Mode Activation (%%ALLMEM-SET) Scan QR Code for Data Uploads (%%ALLMEM-SC)

Maintenance
Cleaning
To clean the scanner, use a soft, dry cloth. For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaner. Do not use harsh chemicals or abrasive materials, as they may damage the device.
Storage
Store the scanner in a cool, dry place away from direct sunlight and extreme temperatures. When not in use for extended periods, ensure the battery is partially charged (around 50%) to preserve its lifespan.
Durability
The scanner features an IP54 dust and waterproof rating and a high-strength ABS+PC material shell, allowing it to withstand drops from up to 1.5m/5ft. While durable, avoid intentional drops or impacts.
