RNKDS-2141Wireless Mouse

Battery r e for 1 PCS new AAA alkaline batteries o n of the mouse upper cover and pull the battery cover e see the reference picture) the batteries correctly according to the polarity marks o oves. r y covers forward, when you hear “crack” sound which r y cover is locked successfully.  n e nded cable, and put the receiver and transmitter on t his way, you may have higher working efficiency. 2 connector, please use the USB to PS/2 adaptor and e connector before your computer start-up. o u may connect the receiver directly with the USB t he mouse near to the receiver b utton 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 8-10 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. Recharge connector 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. 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.

Circuit ‘s Operation Description for 2141-A The main circuit of the mouse transmitter compose by optical IC, MCU and RF department of U2. Inner of U2, L2, D1 and others provide the 3V steady working pressure for circuit, X1 provide the time for system. X2 and inner circuit of the U2 compose RF modulation circuit. when the mouse remove on the desk,U1 can tested this remove and transmitted the data to U2, U2 can received the key’s and coder’s information at the same time. All the message from the eighth of U2 and antenna radio to the free space after coding. SW-ID is connect switch,U2 can radio a message code communication with SW-ID when you press it.D4 is low pressure indicator light ,the light will flash it if you use the mouse when the battery is low pressure and remind you the battery energy is exhaust. The K1 switch can automatically switch to the working state. The system will sleeping if you press K1 when low pressure of U2.
