RNKDS-2101Mini RF Wireless Optical Mouse

No need driver The Steps of Install Battery 1. Please prepare for two PCS new AAA alkaline batteries 2. Press the button of the mouse upper cover and pull the battery cover rearward (Please see the reference picture) 3. Please insert the batteries correctly according to the polarity marks of the battery grooves. 4. Pull the battery covers forward, when you hear “crack” sound, which shows the battery cover is locked successfully. Pr ess and pul l out t he bat t er y cover Put 2 bat t er y and cl ose t he cover Attention Please 1. Please don’t make the mouse far away from the receiver in order to work more smoothly. 2. You’d better use the mouse on the white desk, in this way the batteries can be used in a longer time. Please remove the batteries if the mouse will not be used for a long time. .3. This mouse with saving power sleeping functions, please press any key or scroll the wheel to wake up the mouse when it is sleeping. 4If you want to take off the mouse power, please continue to press the ID switch of the mouse bottom over 3 seconds. If you want to take on the power, please click the ID switch once again. 5The optical mouse will not work freely on a smooth desk, glass, and any reflecting surface, 3D mouse pad. 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 differe n from that to which the receiver is connected. * Consult the dealer or an experienced radio/TV technician fo help.

Circuit ‘s operation Description for DS-2101 TX DS-2101 TX is a wireless mouse project ware, major from step-up chip U1, tiny processor and radio wave produce ware U2, optical chip U3 forms. Battery BAT passes through the built-in electronic switch of L, D1 and the 27 feet of U2, is step-up to make steady 3 V and by C12 strain wave, the 4 feet that enter U2 make U2 work. 3 feet and the 1 of U2 are outside to receive crystal X2 , produce the clock signal of 76.8 KHZ for system. 5, 6, 7 feet difference receive left in 3 right buttons, press the voltage of 3 V enter U2 inside can know the button of which one have been pressed. 16 and 17 feet have received encoder, when encoder turns , make 16 or 17 feet get the voltage of 3 V to enter inside in turn know encoder turn information. 22 feet have set ID switch, press 22 feet get the voltage foot ammunition U2 inside of 3 V project ID signal. 10 and 11 feet produce the vibration of 27.042 MHZ mainly with X2, the signal process owned of U2 that taken over passes through C5 after coding by 12 feet to carry out frequency modulation, produce central frequency 27.045 MHZ, is undertaking frequency the modulation signal of 3 KHZ, in this 9 signal input feet, department carries out radio frequency to enlarge , exports through 8 feet, by C11, L3, C13 and C16, after C17 etc. match , add to PCB antenna to project to space. Battery voltage from R5, R4 divides to press, enter 25 foot detection battery voltages, when voltage passes to low, 20 foot export signals make D5 twinkle. R3 and R2 divide for the voltage of 3 V to press, enter 26 feet to carry out the detection of stabilized voltage. Battery BAT passes through L2, D2 the step-up voltage that 4 V controls from C7 strain wave, the 13 feet that enter U3 make it work , the 7 foot built-in voltage regulators of 3.3 V of U3, C14, C12 carry out voltage strain wave, 9 and 11 feet are outside to receive crystal X4 , produce internal clock, 6 feet is drive give out light the foot of diode D4, the sampling resistance that 14 feet receives can decide the biggest current of D4. When the light of D4 reflects when shooting to top of a table, enters U3, built-in optical induction partially automatic detection and calculation mouse move speed and direction, and pass through this data 1, 16 foot biographies give chip U2, U2 at the same time projects this data modulation by antenna to go out. C +, C - is besides receive the port that charges , D3 is used to prevent reverse current.
