1. The HL-W81 wireless scanner uses 2.4G wireless transmission, with a transmission distance of about 20 meters indoors and up to 100 meters outdoors without obstacles. It features fast transmission speed, low error rate, data storage, total scan count, and ID display, making it suitable for both general scanning and simple inventory. It employs one-to-one encryption technology for secure and reliable data.

2. Supports up to 20 barcode scanners to be used simultaneously within the same range without interference, with each scanner having a unique ID number, which can be set to 99 different IDs.

3. Wireless scanners automatically establish a communication connection with the wireless receiver.

4. Plug and play without any driver required.

5. The humanized design allows for manual, automatic, or self-sensing scanning modes (for self-sensing models, the laser scanning is automatically activated when an object is within 0-10cm of the scanner window, and a second scan is performed when the object moves away and then returns). The scanning modes can be selected according to user needs, and the simple operation settings can meet the needs of different industries, making up for the many inconveniences caused by using wired scanners.

6. The high-speed decoder features fast decoding speed, high reading accuracy, and a wide range (capable of scanning 4mil-43mil density barcodes, adjustable to 3mil upon customer's request, with a barcode width up to 40CM, and a data capacity of 50 bits), meeting the various needs of different users.

7. Extended usage time. This machine is powered by a large capacity lithium battery, which can be fully charged once and provide usage time of over 48 hours. It will automatically turn off and enter a dormant state after about 1 minute of inactivity, with almost no current consumption, offering ultra-long standby time.

Special attention: Charge the battery immediately after the low battery warning!
