Video: Demonstrates the three scanning modes of the Eyoyo barcode scanner: Manual Trigger, Continuous Scanning, and Auto-sensing Scanning.
6.1 Manual Trigger Mode
In this mode, press the trigger button once to initiate a single scan. Ideal for precise, controlled scanning.
6.2 Continuous Scanning Mode
The scanner will continuously emit a scan beam without needing to press the trigger. Suitable for high-volume scanning where items are rapidly presented to the scanner.
6.3 Auto-sensing Scanning Mode
The scanner automatically detects when a barcode is presented within its scanning field and activates the scan beam. It enters standby when no object is detected, conserving battery life.
7. Data Upload Modes
The scanner supports two data upload modes:
7.1 Instant Upload Mode
In this mode, scanned barcodes are immediately transmitted to the connected device (PC, phone, tablet). This is the default mode and is suitable for real-time data entry.
7.2 Storage Mode
When out of range or not connected, the scanner can store up to 100,000 barcodes in its internal memory. Once reconnected, you can upload all stored data to your device by scanning a specific 'Data Upload' barcode from the manual. Remember to clear the data after successful upload to prevent duplicate entries.
8. Customization and Settings
8.1 Sound and Vibration Adjustment
You can adjust the scanner's feedback according to your preference:
