Operating Instructions
Scanning Modes
The Tera 3106 scanner offers two primary scanning modes:
- Key Trigger Mode (Manual): Press the trigger button on the scanner to activate the laser and scan a barcode. Release the button after a successful scan.
- Continuous Mode (Automatic): In this mode, the scanner's laser remains active, continuously scanning for barcodes without requiring a trigger press. This is ideal for hands-free operation, especially when used with a scanner stand (not included). You can switch between these modes by scanning specific configuration barcodes provided in the full user manual (if applicable).

Scanning Barcodes
- Point the scanner's laser beam directly at the center of the 1D barcode you wish to scan.
- Ensure the barcode is within the scanner's optimal reading distance.
- Press the trigger (in Key Trigger Mode) or allow the scanner to automatically detect the barcode (in Continuous Mode).
- A successful scan is typically indicated by an audible beep and/or a visual confirmation (e.g., LED indicator). The scanned data will be transmitted to your connected computer.
