Safety Measures z To avoid possible eye damage, never point the presenter at people especially their faces, or look directly into the presenter’s laser beam. z Avoid pointing the presenter’s laser beam at a mirror or other highly reflective surface. z Keep the presenter away from children. z Never view the presenter’s laser beam using telescopic devices, such as a microscope or binoculars. z Any attempt to disassemble, adjust or repair the presenter may result in exposure to laser light or other safety hazards. 5 FCC Caution: Any Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. 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. 6 NOTE The product adopts advance RF technology, the USB receiver will identify the first transmitter which is used. If you want to use different transmitters with the same receiver, please pull off the receiver and plug it again, after 6 seconds, press any key of the transmitter you want to use. Then it can work successfully.

Circuit Description Our V896 is a tool for PPT Presentation，and it includes the following functions: Page up, Page down,Blank and laser pointer. The features of 2.437G RF technology are strong interference capability, high sensitivity, long distance, and no directional requirement. (1) Keyboard circuit consists of k1-K4. They are all pushing switch, used as a simple on-off switch by connecting to the MCU in the circuit. (2) MCU is EM78P153SN，it is an 8-bit micro controller and processor with low-power and high-speed CMOS technology, with a 1024*13-bits OTP-ROM within it. The work voltage in the circuit is 3V. And the available temperature is 0 degrees Centigrade to +70 degrees Centigrade. (3) 2.437GHz RF transmitter is consist of U2(BK2423) ，etc, Antenna While Key is pressed, the status of MCU PIN is changed, MCU wake up from sleep. It commands U2 send 2.437GHz RF signal. The BK2423 is a low cost true single chip 2.437GHz transceiver designed for very low power wireless applications. The circuit is intended for the ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency band at 2400-2483.5 MHz. (4) Laser pointer is consist of D2、Q1、Q2、Q3、R3, R4, R5, R6 etc. D2 is a 650nm red laser diode. The operating voltage of D2 in the circuit is 3V. Q2、Q3 are NPN surface mounted transistor. They are response for current control and amplify. While K3 is pressed, MCU command the D2 send 650nm laser.
