Scanning Process
To scan a barcode or RFID tag:
- Ensure the scanner is powered on and connected to your host device.
- Select the appropriate reading mode (RFID, Barcode, or combined).
- Point the scanner's reading window at the barcode or RFID tag.
- Press the trigger button. The scanner will emit a light beam or RFID signal.
- Upon successful read, the scanner will provide vibration feedback and/or an audible beep, and the indicator lights will change. The data will be transmitted to the connected device.
Features and Indicators
The SR290 is designed with user feedback and clear indicators:
- Vibration Feedback: The device provides tactile feedback upon successful scans, confirming data capture.
- Four-Color Indicator Lights: A set of four distinct colored lights (Red, Yellow, Blue, Green) provide visual cues for battery status, connection status, and scanning feedback.
