4. Setup and Connection
The HC-2000R offers three connection modes: Bluetooth, 2.4GHz Wireless, and Wired USB. No drivers are typically required for installation; it's plug-and-play.
4.1. Bluetooth Connection
This mode allows wireless connection to devices with Bluetooth capability, such as smartphones, tablets, and laptops.
- Ensure the scanner is charged.
- Turn on the scanner.
- Scan the Bluetooth pairing barcode (refer to the quick start guide or a specific barcode in the physical manual if available).
- On your device (phone, tablet, PC), go to Bluetooth settings and search for "HENEX HC-2000R" or similar.
- Select the scanner to pair. A successful connection will be indicated by a specific sound or light on the scanner.
Transmission Distance: Approximately 10m (33ft) in environments with obstacles, up to 50m (164ft) in barrier-free environments.
4.2. 2.4GHz Wireless Connection
This mode uses the included USB dongle for wireless connection to devices without Bluetooth, or for a more stable connection.
- Plug the 2.4GHz 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 will be indicated by a specific sound or light on the scanner.
Transmission Distance: Approximately 50m (99ft) in environments with obstacles, up to 100m (328ft) in barrier-free environments.

Figure 4.1: Wireless Transmission Distances.
This diagram illustrates the effective transmission ranges for both Bluetooth and 2.4GHz wireless connections. Bluetooth offers 15m (49ft) with obstacles and 30m (98ft) in barrier-free environments. 2.4GHz wireless offers 20m (66ft) with obstacles and 50m (164ft) in barrier-free environments.
4.3. Wired Connection
For direct connection and simultaneous charging, use the USB Type-C cable.
- Connect the USB Type-C end of the cable to the scanner.
- Connect the USB-A end of the cable to an available USB port on your computer or device.
- The scanner will function as a wired scanner and charge simultaneously.

5. Operating Instructions
5.1. Scanning Barcodes
To scan a barcode, point the scanner's window at the barcode and press the "SCAN" button. A successful scan will be confirmed by a slight vibration and an audible beep (if not muted).
The HC-2000R utilizes CMOS scanning technology, allowing it to read barcodes from various surfaces, including computer monitors, smartphone screens, tablets, and through glass or plastic shrink wrap.
5.2. Supported Barcode Types
The scanner supports a wide range of 1D and 2D barcode symbologies:
- 1D Barcodes: UPC, EAN, Code128, Code39, Code11, Interleaved 2 of 5, Codabar, MSI, etc.
- 2D Barcodes: PDF417, Data Matrix, QR Code, Aztec Code, Maxicode, etc.

Figure 5.1: Supported Barcode Types.
This image illustrates examples of various 1D barcodes (One dimensional, Incomplete, High density, Deformation, Border) and 2D barcodes (PDF417, Minitype, QR Code, DataMatrix) that the HENEX HC-2000R scanner is capable of decoding.
5.3. Data Transfer Modes
The HC-2000R offers two data transfer modes:
- Instant Upload Mode: Barcodes are transmitted to the connected device immediately after scanning.
- Offline Storage Mode: Barcodes are stored in the scanner's internal memory (16MB, capable of storing up to 12,500 barcodes) and can be uploaded to the connected device later. This is useful when out of range or not connected.

Figure 5.2: Data Transfer Modes.
This image visually explains the two data transfer modes: "Instant upload mode" where scanned barcodes are immediately sent to a connected device, and "Offline storage mode" where barcodes are saved internally for later upload.
5.4. Buzzer and Vibration Settings
The scanner provides tactile feedback (vibration) upon successful scans. The audible buzzer can be configured to be muted for quiet operation in sensitive environments.
6. Battery and Charging
The HENEX HC-2000R is equipped with a 1200mAh Lithium Ion battery, providing extended continuous use and standby time. The scanner can be charged via the included USB Type-C cable by connecting it to a computer or a USB power adapter.

This image highlights the 1200mAh battery capacity of the HENEX scanner, comparing it favorably to "Other Ordinary Scanners" which typically have 500mAh batteries, indicating longer continuous use and standby time.
7. Maintenance
- Cleaning: Use a soft, dry cloth to clean the scanner's exterior. For the scanning window, use a lens cleaning cloth to avoid scratches. Do not use abrasive cleaners or solvents.
- Storage: Store the scanner in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: For optimal battery life, avoid fully discharging the battery frequently. If storing for a long period, charge the battery to about 50% and recharge every few months.
- Firmware Updates: Check the official HENEX website for any available firmware updates to ensure optimal performance and compatibility.
8. Troubleshooting
