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. 。 Receiver Installation 1, please use extended cable, and put the receiver and transmitter on one desktop, in this way, you may have higher working efficiency. 2, If you use PS/2 connector, please use the USB to PS/2 adaptor and connect with the connector before your computer start-up. 3, For laptop, you may connect the receiver directly with the USB connector. ID Setup 1, Please move the mouse near to the receiver 2, Press the ID button of the mouse bottom with some hard and acuate object within 10 seconds, the receiver light will flash very fast, a few seconds later it will be on which shows it is successfully to finish the digital transmission between the mouse and the receiver. You may start to use it. 3. Working distance: within 0.6-1.5 m Charge Function When using mouse, if the red led of the low battery beside the wheel flashes, please change batteries or charge them .The mouse can use USB line to charge, connect one side of USB line to the connector of the board, and the other side to USB connector before the mouse, thus it can successfully charge the battery. It can charge while you use the mouse. It is full within about 3-4 hours, and then unplug the connector to stop the charge. Please note that the time of charge may vary when the degree of discharge is different. 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 longer time. Please remove the batteries if the mouse will not be used for a long time or if you travel outside. 3. This mouse with save power sleeping functions, please press any key or scroll the wheel to wake up the mouse when it is sleeping. 4. If you want to take off the mouse power,please continue to press the ID switch of the mouse bottom over 3 secons.If you want to take on the power,please click the ID switch once again. 5. The optical mouse will not work freely on a smooth desk ,glass, any reflecting surface, 3D mouse pad. 6. When you move the mouse, if the light of the battery before the receiver flashes, which shows that the power is nearly finished. Please change the proper-sized new battery or charge it immediately. 7. You can place the receiver in the mouse when you want to carry the mouse on business, and press the switch of ID for a long time so as to switch off the power. 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 interfer- ence 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-2128 Mouse projects the circuit of ware, is formed mainly by optical IC U1 and MCU and RF partial U2s. U3, U4 and periphery related element composition DC-DC change-over circuit export steady 3 V and the voltage of 4 V respectively to U2 and U1 to supply power. X1 offers clock for system. X2 and the internal circuit of U2 enlarge circuit to RF modulation. When mouse moves on top of a table U1 can detection arrive this kind of move and turn data deliver to U2, U2 at the same time takes over the information of button and encoder, all informations go through coding after go through the modulation of radio frequency enlarge after from the 8 foot outputs of U2 and from antenna project free space. SW-ID is for yard switch, press rear U2 to project a information yard make receiver carry out dimension a communication to it. D3 is low voltage indicator light, when battery voltage is below , if you use this mouse lamp, the energy that can twinkle and reminds battery has used quickly. K1 switch can be automatic to switch working state, according to next K1 because the voltage drop of supply U2 is low, make whole system have entered Xiu the state of eye. Receiver is formed by RF receiver U1 and MCU U3 and ID yard memory ware U2. Y2 and environmental element composition local oscillator, project ware the signal that projects from antenna induction rear input and book shake to mix frequently rear B1 strain wave, by X1, carry out frequency detection. Detection after from Q1 plastic after from the 14 feet of U1 lose U3, U3 passes through USB interface CN1 biography for the signal that taken over after decode to computer. If press for yard switch SW, U3 will mouse project ware hair come to ID yard signal preservation go to EEPROM U2 in, in order machine lose electricity after next again load addition again can with project ware carry out only communication.
