Abstract This manual provides specifications for the OPL-2724 wireless barcode scanner. This scanner is a laser barcode scanner which is able to detect black or colored barcodes on the white or colored back ground. 2. Overview OPL-2724 is a wireless barcode scanner. The use of a short-wavelength red laser beam enhances visibility when scanning lines. To scan a barcode, press the trigger switch without the optical window of this scanner touching the objective barcode. Supported symbologies are: WPC (EAN, JAN, UPC-A / UPC-E), industrial 2of5, IATA, interleaved 2of5, NW-7 (Codabar), Code-39, Code-93, Code-128, EAN-128 and MSI Plessey. Code options, read options and communication settings can be configured by sending commands. Scanned data is transferred to the designated device via wireless communication (Bluetooth V2.0). If the OPL-2724 is disconnected because it is out of range or the Bluetooth device is not available, scanned data will be saved in the built-in memory of the scanner. OPL-2724 uses 2 size AAA alkali batteries for its power supply. This product is compliant with RoHS. 3. Physical Features 3-1.

Bluetooth • • • • • • • Bluetooth® is a trademark owned by its proprietor and used by OPTOELECTRONICS Co., Ltd. under license. To communicate via Bluetooth, the divice which OPL-2724 is connected to, must support the same Bluetooth version and profile. OPL-2724 is compliant to Bluetooth standards. However, we cannot assure the connection between OPL-2724 and other Bluetooth devices which have not been tested. Bluetooth supporting devices use 2.4 GHz frequency band. However, many other sorts of devices also utilize this frequency band. It may effect the communication speed or communication range of this scanner. The use of OPL-2724 outside of the European Union, the United States and Canada is punishable under the law. Communication speed and communication range of OPL-2724 may differ due to the obstcles and radio wave conditions between OPL-2724 and the divice, which OPL-2724 is connected to. Conditions of the divice, which OPL-2724 is connected to, may also effect the communication speed and communication range of OPL-2724. Expected interference distance is up to 10 meters. 22. Frequency Band The frequency band 2.4 GHz is utilized by this scanner. Read carefully the followings before using this product. In the frequency band of this scanner, scientific, medical and industrial devices including microwaves are used. Also other radio stations including local private radio station for mobile object identification requiring license for such as manufacturing lines at factories, specific power-saving radio station requiring no license and amatuer radio station are managed. 1. Please make sure that “other radio stations” are not managed in the frequency band 2.4 GHz before using this scanner. 2. In case that radio interference occurs between this scanner and “other radio stations,” change the service space immediately, or stop transmitting radiowave to avoid the interference. *If you have any questions or troubles, please contact our marketing group. Handle product in accordance with this specification. -2- FCC Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: -Reorient or relocate the receiving antenna. -Increase the separation between the equipment and receiver. -Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. -Consult the dealer or an experienced radio/TV technician for help. FCC Radiation Exposure Statement This device complies with Part 15 of FCC RF Rules. Operation is subject to the following two conditions: 1) this device may not cause interference and 2) this device must accept any interference, including interference that may cause undesired operation of the device.
