2. Setup
2.1 Charging the Scanner
Before first use, fully charge the scanner. Connect the USB cable to the scanner and a power source (e.g., computer USB port or USB wall adapter). The built-in 2000mAh battery provides approximately 16.5-19.5 hours of continuous scanning time and up to 60 days of standby time.

This image highlights the scanner's 2000mAh battery capacity and the visual battery level indicator, showing working time, charging time, and standby time.
2.2 Connection Modes
The Tera HW0002 supports three connection modes: Bluetooth, 2.4G Wireless, and USB Wired.

This diagram illustrates the three available connection methods: Bluetooth for wireless pairing with devices, USB for direct wired connection, and 2.4G wireless via a USB dongle.
2.2.1 2.4G Wireless Connection (via Dongle)
- Insert the 2.4G USB dongle into an available USB port on your computer or device.
- Turn on the scanner. It should automatically connect to the dongle.
- A successful connection is indicated by a specific sound or LED light on the scanner.
- The transmission distance can reach 328ft in open environments and 114ft in environments with obstacles.
2.2.2 Bluetooth Connection
- Ensure Bluetooth is enabled on your host device (smartphone, tablet, computer).
- Scan the "Bluetooth Pairing" barcode (refer to the physical manual for this barcode).
- On your host device, search for available Bluetooth devices and select "Tera HW0002" (or similar).
- Pair the devices. A confirmation sound or LED light on the scanner will indicate successful pairing.
2.2.3 USB Wired Connection
- Connect the scanner to your computer using the provided USB cable.
- The scanner will function as a standard USB HID keyboard device. No additional drivers are typically required.
3. Operation
3.1 Basic Scanning
Point the scanner at a 1D or 2D barcode and press the trigger button. The scanner will emit a light beam to read the barcode. A successful scan is indicated by a sound, LED illumination, and a mild vibration (if enabled).

This image demonstrates the Tera HW0002 scanner's ability to read both 1D and 2D barcodes directly from digital screens, such as computer monitors.
3.2 Hands-free Scanning with Stand
The included stand allows for hands-free operation. Place the scanner in the stand, and it can be configured for continuous scanning or trigger-activated scanning while docked.

This image shows the barcode scanner positioned in its stand on a desk, ready for hands-free scanning, ideal for environments requiring frequent item processing.
3.3 Advanced Settings
The scanner can be configured by scanning specific barcodes found in the full user manual. These settings include:
- Volume and Vibration Settings: Adjust the sound level (Off, Low, Medium, High) and enable/disable vibration alerts for successful scans.
- Symbology-Specific Settings: Customize data output for specific barcode types (e.g., Code39). For example, you can set the scanner to delete the first 2 characters and add 2 TAB characters when scanning Code39, while leaving other barcode types unedited.
- Prefix/Suffix Addition: Add custom characters or data (like date and time) before or after scanned barcode data.
- Upload Modes: Choose between Storage Mode (scans are stored internally and uploaded later) and Instant Upload Mode (scans are transmitted immediately).
- Multi-Language Support: Configure the scanner for various keyboard layouts to ensure correct character output.

This graphic illustrates the adjustable volume levels (Off, Low, Medium, High) and the option to toggle vibration alerts on or off for scan confirmations.

This image shows how the scanner can be configured to add the current date and time either before (prefix) or after (suffix) the scanned barcode data.

This diagram illustrates the two data upload modes: Storage Mode, where scanned data is saved internally for batch upload, and Instant Upload Mode, where data is transmitted immediately after each scan.
4. Maintenance
4.1 Cleaning
To maintain optimal scanning performance, keep the scanner's optical window clean. Use a soft, lint-free cloth, slightly dampened with water or a mild cleaning solution. Avoid abrasive materials or harsh chemicals.
4.2 Battery Care
- Charge the scanner regularly, especially if it will be stored for an extended period.
- Avoid fully discharging the battery frequently, as this can reduce its lifespan.
- Store the scanner in a cool, dry place when not in use.
5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Scanner not turning on. | Low battery. | Charge the scanner for at least 3-4 hours. |
| Scanner not connecting via 2.4G. | Dongle not properly inserted or not recognized. | Ensure the dongle is firmly inserted. Try a different USB port. Re-pair if necessary (refer to manual for pairing barcode). |
| Scanner not connecting via Bluetooth. | Bluetooth not enabled on host device, or scanner not in pairing mode. | Enable Bluetooth on your device. Scan the "Bluetooth Pairing" barcode in the manual. Ensure no other devices are interfering. |
| Scanned data is incorrect or missing characters. | Incorrect keyboard layout setting or symbology-specific settings. | Scan the appropriate barcode from the manual to set the correct keyboard layout for your region. Review symbology-specific settings. |
| Scanner not reading barcodes. | Barcode damaged, poor lighting, or scanner lens is dirty. | Ensure the barcode is clear and well-lit. Clean the scanner lens. Try scanning a different, known-good barcode. |
| No sound or vibration on successful scan. | Volume or vibration alert is disabled. | Scan the appropriate barcodes from the manual to enable sound and vibration alerts. |
