4. Setup
Your Symcode 1D Ring Barcode Scanner offers three primary connection methods to suit your operational needs.
4.1 Charging the Scanner
Before initial use, fully charge the scanner. Connect the provided USB charging cable to the scanner's micro-USB port and the other end to the USB power adapter or a computer's USB port. The indicator light on the scanner will show charging status (e.g., red for charging, green for fully charged).
4.2 Connection Methods
Turn on the scanner using the On/Off switch located at the back.
2.4G Wireless Connection
For devices without Bluetooth or for a dedicated wireless connection:
- Insert the 2.4G wireless receiver (dongle) into an available USB port on your computer or POS system.
- The scanner will automatically pair with the receiver. A successful connection is usually indicated by a specific sound or light pattern on the scanner.
Bluetooth Connection
For mobile devices, tablets, or computers with Bluetooth capability:
- Ensure Bluetooth is enabled on your host device (smartphone, tablet, laptop).
- On your host device, search for available Bluetooth devices. The scanner should appear as "Barcode Scanner HID" or similar.
- Select the scanner to pair. Once paired, the scanner is ready for use.
USB Wired Connection
For direct and stable connection, or when charging:
- Connect the scanner to your computer using the provided USB charging cable.
- The scanner will function as a wired scanner and also charge simultaneously.

5. Operating Instructions
Once connected, your Symcode 1D Ring Barcode Scanner is ready to scan.
5.1 Basic Scanning Operation
- Wear the scanner comfortably on your finger.
- Point the scanning head towards the barcode you wish to read.
- Press the yellow activation button on the side. A red laser line will appear, and a successful scan will be indicated by a beep and/or vibration.
- The scanned data will be transmitted to your connected device.
5.2 Upload Modes
The scanner supports two data upload modes:
Instant Upload Mode
In this mode, barcode data is immediately transmitted to your connected device as soon as it is scanned. This is suitable for real-time inventory management or POS operations.
Storage Mode
When out of range or when real-time transmission is not required, the scanner can store up to 50,000 barcodes in its internal 16MB memory. Data can be uploaded to your device later by switching to instant upload mode or connecting via USB.

Image: This graphic explains the two data upload modes: Instant Upload, where data is sent immediately, and Storage Mode, where data is saved internally for later transfer.
5.3 Transmission Distance
The effective transmission range varies based on the connection type and environment:
- 2.4G Wireless: Up to 150m (492ft) in a barrier-free environment; up to 30m (98ft) with barriers.
- Bluetooth: Up to 50m (164ft) in a barrier-free environment; up to 15m (49ft) with barriers.

- Scanner not reading barcodes: Ensure the barcode is clean and not damaged. Verify that the scanner's laser is active when the button is pressed. Check the reading distance and angle. Ensure the barcode type is supported by the scanner.
- Scanned data not appearing on device: Confirm the scanner is successfully connected to your device. Check if the scanner is in storage mode; if so, switch to instant upload mode or manually upload stored data.
