Operating Instructions
Scanning Barcodes
Point the scanner's light beam at the 1D barcode you wish to scan. Ensure the beam covers the entire barcode. A successful scan is typically indicated by a beep (if enabled) and/or vibration (if enabled).

Scanning Modes
The scanner supports two primary data upload modes:
- Instant Upload Mode: Barcode data is transmitted directly to the connected device immediately after scanning. This is the default mode.
- Storage Mode: Barcode data is stored in the scanner's internal 16MB memory. This mode is useful when out of range or not connected to a host device. Data can be uploaded later by scanning a specific command barcode (refer to the full manual for command barcodes). The scanner can store over 100,000 barcodes in this mode.

Sound and Vibration Settings
The scanner provides audible and tactile feedback for successful scans. These settings can be adjusted:
- Turn On/Off Sound: Scan the appropriate command barcode from the full user manual to enable or disable the beep sound.
- Turn On/Off Vibration: Scan the appropriate command barcode from the full user manual to enable or disable vibration feedback. This is ideal for quiet environments.

Data Customization
You can configure the scanner to modify the output data:
- Add/Hide Prefixes/Suffixes: Append custom characters before or after the scanned barcode data.
- Delete Characters: Remove specific characters from the scanned data.
- Append Keyboard Keys: Add special keys like TAB or Enter after each scan for automated data entry.
Refer to the comprehensive programming guide in the full user manual for specific command barcodes to implement these customizations.

- Driver Installation: For some systems, a driver might be required for the 2.4G dongle or USB connection. Check your operating system's device manager.
Scanner Not Reading Barcodes
- Barcode Type: This device is exclusively designed to read printed 1D barcodes. It cannot scan electronic codes from screens (e.g., 1D or 2D QR codes on phones/computers) or any printed 2D codes.
- Barcode Condition: Ensure the barcode is not severely damaged, smudged, or poorly printed. While the scanner has superior decoding, extreme damage can prevent reading.
- Distance and Angle: Adjust the distance and angle between the scanner and the barcode.
- Lighting: Ensure adequate lighting, but avoid direct glare on the barcode.
- Scanner Window: Clean the scanner's optical window if it is dirty.
