3. Operating the Scanner
3.1 Scanning Modes
The scanner supports two primary scanning modes:
- Key Trigger Mode: Press the trigger button to scan each barcode individually.

3.2 Upload Modes
The Tera HW0004 offers two data upload modes:

Image: Diagram illustrating the two upload modes: Instant Upload Mode and Storage Upload Mode with 16MB memory.
3.2.1 Instant Upload Mode
In this mode, scanned barcode data is immediately transmitted to your connected device. This is suitable for real-time data entry.
3.2.2 Storage Upload Mode
When operating out of wireless signal range, or for batch processing, barcodes can be scanned and stored in the scanner's built-in 16MB memory. Data can then be uploaded to your computer at a later time when a connection is established.
3.3 Supported Barcode Types (1D)
The scanner supports various 1D printed barcode symbologies:
- Code 39
- UPC-A/UPC-E (including Complement Code)
- EAN13, EAN8
- Code 93
- Code 128
- Codabar
- Industrial/Interleaved 2 of 5
- MSI
- Code11
- ISBN/ISSN
- Matrix 2 of 5
- And others.

3.4 Unsupported Barcode Types and Scanning Surfaces
The Tera HW0004 scanner does not support:
- 2D codes (e.g., QR codes, PDF417)
- Scanning directly from screens (e.g., mobile phones, computer monitors)
3.5 Multifunction Settings
The scanner includes several configurable functions:
- Voice Setting: Adjust or disable audible feedback.
- Stand-by Setting: Configure the idle time before the scanner enters power-saving mode.
- Support Uppercase / Lowercase Setting: Define how character cases are handled.
- Identify Barcode Type: Enable or disable automatic identification of barcode symbologies.
- Add Prefix and Suffix: Customize data output by adding characters before or after the scanned barcode data.
- Hide Characters: Configure the scanner to omit certain characters from the output.
Refer to the programming barcodes provided in the supplementary guide (if applicable) to configure these settings.
4. Maintenance
4.1 Cleaning the Scanner
To maintain optimal performance, keep the scanner's scanning window clean. Use a soft, lint-free cloth, slightly dampened with water or a mild, non-abrasive cleaning solution. Avoid harsh chemicals or abrasive materials that could scratch the window.
4.2 Battery Charging
For wireless operation, ensure the scanner's internal battery is adequately charged. Connect the scanner to a USB power source using the provided USB cable. The charging indicator light will show the charging status.
5. Troubleshooting
5.1 Common Issues
- Scanner not connecting: Ensure the USB cable is securely connected or the wireless dongle is properly inserted and the scanner is powered on. Try a different USB port.
- No data output: Verify the scanner is in the correct upload mode (Instant or Storage). Check if the target application (e.g., Word, Excel) is active and ready to receive input.
- Scanner not scanning: Ensure the laser is emitting. Check for obstructions on the scanning window. Confirm the barcode type is supported.
- Incorrect data output: Review multifunction settings for prefixes, suffixes, or character hiding. Ensure the correct keyboard language is set on your computer if experiencing character mapping issues.
5.2 Decoding Ability
The Tera HW0004 features powerful decoding capabilities, allowing it to read various challenging 1D barcodes:

Image: Examples of the scanner's ability to decode damaged, fuzzy, reflective, and smudged 1D barcodes.
- Damaged Barcodes: Can often read barcodes with minor damage or tears.
- Fuzzy Barcodes: Capable of decoding barcodes that are slightly out of focus or poorly printed.
- Reflective Barcodes: Designed to minimize interference from reflective surfaces.
- Smudged Barcodes: Can read barcodes with minor smudges or ink bleed.
For persistent issues, refer to the full programming guide or contact customer support.
