2.4G Wireless Laser Scan Barcode Bar Code Scanner Handheld Decoder Reader Gun High Speed Features: Uses 2.4G RF bi-directional wireless data transmission module. Automatic frequency hopping, strong anti-interference capability. Superspeed 280Kbps wireless transmission rate. The communication distance in the open place is up to 200 meters. (The specific distance depends on the use environment.) Plug-n-play, USB receiver automatic pairing, no any driver is needed. Easy to check and can storage 5,000 barcode data. Automatic sleep mode and low voltage protection of the battery, largely prolongs the standby time of the battery.    Rich decoding types, advanced long-range functionality and long service life of button (up to 60,000,000 times). Support the keyboard output of more than 20 different languages. If the transmission distance is beyond the effective distance or data is not uploaded successfully, three short alarms will be given for prompt.  The independent mechanical ID enables each scanner has a unique identification number and guarantees that many sets of products cannot disturb each other when working simultaneously. Bright and sharp laser beam reads thin barcodes accurately and correctly. Wireless & handheld, very convenient and portable e. Compact anti-shock & drop-resistance design, durable & . Widely used in all walks of life, such as supermarket, bank, warehouse, logistics & express, etc. Note: DO NOT point the scanner's laser beam to eyes.   Frequency 2.4G Communication distance 200m Light source Visible lasing diode; Wave length: 650nm Scanning mode Bi-directional single line scanning Scanning speed 280 scans / sec Scanning accuracy 0.10mm PCS0.9 Scanning width 30mm @ The scanner window, 220mm @ 200mm Scanning depth of field 0~350mm (0.43mm, PCS 98%) Tilt & Elevation & Deflection 30° & 75° & 65° Interfaces supported USB Print contrast ratio At least 30% reflectivity difference Error rate 1/5,000,000 Promoting methods Buzzer, LED indicator Scanning ways Trigger manually or continuous scanning Decoding abilities EAN-8, EAN-13, UPC-A, UPC-E, Code 39, Code 93, Code 128, EAN128, Codaber, Industoal 2 of 5, Interleave 2 of 5, Matrix 2 of 5, MSI, China postal code, etc. Power source DC5V Battery type 800mA Lithium ion battery  Working current 130mA (Total power consumption: 650mw) Quiescent current 70mA Laser safety National safety standard Class 2 Electromagnetic compatibility CE, FCC, DocCompliance Operating temperature 0 ~ 45 degree Celsius Storage temperature -20 ~ 60 degree Celsius Humidity Relative humidity 5% ~ 90% (No condensation) Ambient brightness Max. 5,000 lux (fluorescence) Anti-knock Can withstand 1.8m free fall Material ABS + PC + Rubber Cable length Approx. 80cm / 31.49in Product size Approx. 8.7 * 7 * 16.8cm / 3.43 * 2.76 * 6.61in Product weight Approx. 135g / 4.76oz Package size Approx. 20 * 10.3 * 8cm / 7.87 * 4.06 * 3.15in Package weight Approx. 340g / 11.9oz Package List: 1 * Wireless laser barcode scanner 1 * USB charging cable 1 * USB charge adapter 1 * Wireless receiver 1 * User manual (English)
