3. Operating Instructions
3.1 Barcode Compatibility
The HC-651D scanner offers powerful decoding capabilities, supporting a wide range of 1D and 2D barcodes from both paper and digital screens (e.g., phone screens, computer screens). It can read distortion, damaged, colorful, and reflective barcodes.
- 1D Barcodes: EAN, UPC, Code 39, Code 93, Code 128, UCC/EAN 128, Codabar, Interleaved 2 of 5, ITF-6, ITF-14, ISBN, ISSN, MSI-Plessey, GS1 Databar, Code 11, Industrial 25, Matrix 2 of 5, etc.
- 2D Barcodes: QR Code, DataMatrix, PDF417, Aztec Code, Maxi Code, etc.

3.2 Scanning Modes
The scanner supports three types of scanning modes to suit different operational needs:
- Manual Trigger Mode: Press the trigger button to scan each barcode individually. This is the default and most frequently used mode.
- Continuous Scan Mode: The scanner continuously emits a scan line, automatically reading barcodes as they are presented. This mode is suitable for high-volume scanning.
- Auto-sensing Scan Mode: The scanner automatically detects a barcode when it is placed in front of the scanning window and initiates a scan. This mode is especially useful when using the scanner with a stand for hands-free operation.

3.3 Self-Sensing Mode with Stand (if applicable)
If your scanner model includes a stand, it can automatically switch between manual and self-sensing modes:
- Self-Sensing-on: When the scanner is placed on its stand, it automatically switches to self-sensing mode, allowing for hands-free scanning.
- Self-Sensing-off: When the scanner is lifted from the stand, it automatically reverts to manual trigger mode.

3.4 Powerful Edit Functions
The scanner supports various data editing functions to customize your barcode output:
- Add Prefix: Add characters before the scanned barcode data.
- In The Middle: Insert characters within the barcode data.
- Add Suffix: Add characters after the scanned barcode data.
- Hide Front/End: Conceal specific characters from the beginning or end of the barcode data.
Refer to the full instruction manual (if available as PDF) for specific programming barcodes to activate these functions.

3.5 Beep Setting
You can adjust the scanner's beep sound settings:
- Turn on Sound: Activates the audible beep for successful scans.
- Turn off Sound: Disables the audible beep.
Refer to the full instruction manual (if available as PDF) for specific programming barcodes to change the beep settings.

4. Maintenance
4.1 Cleaning the Scanner
To ensure optimal performance and longevity of your scanner:
- Use a soft, clean cloth slightly dampened with water or a mild cleaning solution to wipe the exterior of the scanner.
- For the scanning window, use a lint-free cloth and a non-abrasive cleaner specifically designed for optics.
- Do not use harsh chemicals, abrasive cleaners, or excessive moisture, as these can damage the device.
4.2 Storage

7. User Tips
- For optimal scanning, ensure the barcode is flat and well-lit. Avoid scanning through highly reflective surfaces if possible.
- When scanning from digital screens, adjust the screen brightness to a medium level to prevent glare and improve readability.
- If you need to customize data output (e.g., add prefixes/suffixes), refer to the detailed programming guide (often included as a separate document or available from the manufacturer's support website) for the specific barcodes to scan.
- The compact size (approximately 9.2 x 4.1 x 2.9 inches) and lightweight design (around 200g) make it comfortable for extended handheld use.
