Components:
- Barcode Scanner Unit: The main handheld device for scanning.
- Auto-Sensing Stand: Allows for hands-free scanning and automatic mode switching.
- USB Receiver: For wireless connection to your computer.
- USB Charging Cable: For recharging the scanner's internal battery.
3. Setup
3.1 Charging the Scanner
The scanner is equipped with an 1800mAh rechargeable battery. Before first use, fully charge the scanner. Connect the USB charging cable to the scanner and a power source (e.g., computer USB port, USB wall adapter). A full charge typically takes approximately 4 hours.

Figure 3.1: The scanner features an 1800mAh rechargeable battery, providing up to 30 hours of scanning time and 720 hours of standby time with a 4-hour charging duration.
3.2 Connecting the USB Receiver
Insert the USB receiver into an available USB port on your computer (laptop or desktop). The scanner will automatically attempt to pair with the receiver.
3.3 Pairing Modes
The scanner supports two pairing modes:
- One-to-one Mode: One scanner transmits barcode data to a single USB receiver.
- More-to-one Mode: Multiple scanners can transmit barcode data to a single USB receiver. This is ideal for environments where several users are scanning simultaneously, such as a warehouse.

Figure 3.2: Illustration of the two pairing methods: one scanner to one receiver, and multiple scanners to one receiver.
3.4 Auto-Sensing Stand Configuration
The scanner automatically switches to auto-sensing mode when placed on its stand and to manual key mode when removed. No special setup code is required for this functionality.

Figure 3.3: The scanner automatically switches between manual key mode (Self-Sensing-off) when off the stand and self-sensing mode (Self-Sensing-on) when on the stand.
4. Operating the Scanner
4.1 Scanning Modes
- Manual Trigger Mode: When holding the scanner in hand, press the trigger button to activate the scan beam and read barcodes.
- Auto-Sensing Mode: When the scanner is placed on its stand, it will automatically detect barcodes presented in front of it and scan them without requiring a trigger press.

Figure 4.1: The scanner supports Instant Upload Mode for real-time data transfer and Offline Storage Mode, capable of storing up to 100,000 barcodes.
4.2 Data Upload Modes
The scanner offers two methods for uploading scanned data:
- Instant Upload Mode: Barcode data is synchronously uploaded to your computer immediately after scanning.
- Offline Storage Mode: Barcodes are stored internally within the scanner (up to 100,000 barcodes). You can then upload the stored data to your computer when needed.
4.3 Supported Barcode Types
The Symcode scanner can easily scan a wide range of 1D and 2D barcodes, including:
- 1D Barcodes: UPC/EAN, Code 128, Code 39, Code 93, Code 11, Interleaved 2 of 5, Industrial 2 of 5, Matrix 2 of 5, Standard 2 of 5, Codabar, MSI Plessey, GS1 DataBar, etc.
- 2D Barcodes: QR Code, DataMatrix, PDF417, Aztec, Hanxin, etc.
It can read barcodes from various sources, including printed labels, paper documents, and digital displays on mobile phones or computers, even if they are partly damaged, dirty, or poorly printed.

4.4 Transmission Distance
The wireless transmission technology provides a long range:
- Up to 200m (328ft) in open air.
- Up to 30m (98ft) indoors.

Figure 4.3: The scanner offers long transmission distances, up to 30m/98ft indoors and 200m/328ft in open areas.
4.5 Customization Options
The scanner offers multiple configuration options for enhanced usability, including:
- Automatic sensing adjustment.
- Hiding barcode characters.
- Adding custom prefixes or suffixes to scanned data.
- Volume adjustment for scan confirmations.
4.6 Battery Level Indicator
The unique battery indicator light on the scanner provides real-time feedback on the remaining battery level, helping to prevent unexpected power loss.

Figure 4.4: The scanner features a real-time battery level indicator and options to turn on/off beep and vibration feedback.
4.7 Beep and Vibration Indicators
You can configure the scanner to provide audio (beep) and/or tactile (vibration) feedback upon successful scans. Refer to the included setup codes in the full manual for specific instructions on enabling or disabling these features.
5. Maintenance
5.1 Cleaning
To maintain optimal performance, regularly clean the scanner's scanning window and exterior. Use a soft, dry, lint-free cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the device.
5.2 Battery Care
For best battery longevity and to achieve full storage capacity, allow the battery to undergo a few (typically 5-6) full charge-discharge cycles from flat, rather than frequent top-ups. This helps calibrate the battery indicator and maximize its lifespan.
6. Troubleshooting
Common Issues and Solutions:
- Scanner not connecting/pairing: Ensure the USB receiver is securely plugged into your computer. Try a different USB port. Verify the scanner is powered on.
- Scanner not reading barcodes: Ensure the barcode is clean, not excessively damaged, and properly illuminated. Check that the scanner is in the correct operating mode (manual or auto-sensing).
- No data transmission: Confirm the scanner is paired correctly. Check if the scanner is in offline storage mode; if so, upload the data manually.
- Short battery life: Ensure the scanner is fully charged. Over time, battery capacity may decrease. Follow battery care guidelines in Section 5.2.
- Incorrect data output (e.g., missing characters): This might be related to programming settings. Refer to the full product manual for specific setup codes to reset or adjust prefix/suffix settings.
If you encounter persistent issues not covered here, please refer to the comprehensive manual provided with your product or contact Symcode customer support.
