# Scan Mode

## Key Trigger Mode
Press the button to trigger scanning, and release the button to end scanning. Scanning ends when the scan is successful or the reading time exceeds the single reading time.

## Continuous Mode
The scanner works continuously. If the scan is successful or the scan time exceeds the single working time, the current scan ends. If the time exceeds the specified time, the next scan is automatically triggered.

## Auto Sensing Mode
In the auto sensing mode, the scanner will detect the brightness of the surrounding environment. When the brightness changes, the scan is triggered. The scan ends when the scan is successful or the scan time exceeds the single working time. Regardless of whether the last scan was successful or failed, the brightness of the surrounding environment will be detected again.

## Same Code Delay Settings
To prevent the same barcode from being scanned multiple times in [Continuous Mode](#continuous-mode) and [Auto Sensing Mode](#auto-sensing-mode), you can require the scanner to wait for a set delay before allowing the same barcode to be scanned.

### No Delay
