Battery Installation Open the battery cover on the bottom of the mouse, insert two brand new batteries, (please note that “+”and “-” should be putting at the right side or it will cause short circuit)(As per Picture) WARNING: Different kinds of batteries (e.g. Alkaline and Rechargeable batteries) mixed using may cause explosive damage. 3. Adjusting code Before using it, please be sure that the adjusting code are not interfered, for example, when several mice are used at a close distances, the ID codes can be set through the buttons on the bottom of the mouse, Thus, it start working within 4 seconds either of them can be pressed first (As per Picture). 4. Usage The receiver (box) can be placed any distance within 1.5M to 2M. Mouse can be used on any desktop surface. (We recommend to use it on any white or lighter color surface of desktop, thus, the power can be saved.) Simple maintenance and technique support If you are not going to use it for a long time, please take the batteries out to avoid any damages on the circuit or if replacement time for batteries is too long, the adjusting code needs to be reset. In case it cannot be used, do not open up the mouse yourself. You should contact the service center that near by your place. Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. Note: Note: 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.

Circuit ‘s operation Description for DS-2038 This circuit is mainly consisted of convertor IC(U3,U4), IC(U1), MC(U I), C(U2). IC U4 provides the circuit with a stable 3Vvolts d.c and U3 provide the circuit with a stanble 4V . to keep the circuit working. when the mouse is moving on the desktop, photoelectric processor IC-U1collect optical signals reflected by the desktop and transfer them into the MCU IC-U2, then processed and managed. By MCU together, they are sent to the FSK circuit. In the MCU IC-U2,there is internal RF Generator the electric signals out from MCU will be generated, and output the data from 8# feet of U2 and radiate the signal to outside. MCU will provide and generate a code from the 22# feet of IC-U2 when you press the ID buttonat the same time ,MCU will storage this code, and keeping the ID code unchanged until out of power. The MCU IC-U2 have two functions of sleep and wake up. For saving up the capacity of power, the circuit will keep sleeping model when the mouse has stopped on the desktop for a fixture time; you can press any key or wheel switch to let it work again.
