1、2.4G wireless transmission of signals caused by interference or blocking of the reasons?
A、Obstacle influence; 2.4G shorter wavelength, diffraction is not strong, and easily absorbed by fiber, so between the receiver and transmitter, the more obstacles, the greater impact. Barrier metal chassis, will also use the receiver can be plugged into the front USB port host.
B、Electronic interference; electronic products are subject to regular national testing agencies Safety Test. Such as: domestic CCC, SRRC, the U.S. FCC, European CE; some radiation exceeds the non-standardized products will.affect the 2.4GHz data transmission, affecting the distance
C、Environmental impact; 2.4G for some magnetic field, current pulse is very sensitive, and should be avoided
2、2.4G wireless signal across the sexual performance?
Shorter wavelength as 2.4G, through radio signals will be attenuated when the wall from the discount, glass doors, wooden walls relative to iron, steel and concrete walls slightly better mixed
3、27M, 2.4G, Bluetooth What is the difference between the three?
A、27M wireless mouse and keyboard for the initial use of wireless technology products, and only 1.5 meters effective range, the data transmission rate is low, you need to work continuously, so power-hungry; one-way signal transmission mode intermittent prone situations; In addition the security level is low, prone to interfere with each other similar products
B、2.4G data transmission rate, and transmission efficiency of the 2Mbps, than 27M 416 times faster transmission speed can be processed more quickly once the signal is sent in the greatly reduced power consumption, the mouse sensitivity is improved; two-way transmission, to avoid the code missing data; automatic frequency that can automatically find available spectrum, avoid interference; each product pairing built-ID code between different brands of products do not mix
C、Bluetooth uses the same frequency with the 2.4G, but stronger anti-interference ability. 2.4G wireless Bluetooth technology in general increase the frequency of adaptive technology, frequency hopping to avoid interference with the communication process automatically jump nodding, and the minimum transmission power, the lowest probability of being intercepted.No interference in frequency hopping to achieve long time to maintain high-quality communication channel purpose; to achieve full-duplex transfer mode (transmit data can receive data at the same time), 1,600 times / sec auto-FM. In addition, the technology enables the receiver of the Bluetooth device and transmission of both parties to 1Mhz intervals, in its 79 sub-bands by each pairing; Bluetooth mouse use is also high, a lot of notebooks and other products are integrated within the Bluetooth module, a variety of Bluetooth wireless connection between the agreement can be achieved; however, a larger power consumption Bluetooth
4、Wireless 2.4G products to energy-efficient?
2.4G transmission rate 4800bps, than 27M 416 times faster transmission speed, transfer rate speeds up, so 27M wireless 2.4G wireless faster than the one processed signal transmission, therefore, power consumption and greatly reduced 2.4G wireless to extend battery life
5、2.4G mouse to play the game?
Certainly, the number of wireless 2.4G and efficient transmission rates to make the mouse more responsive and effective performance enhancing, then it will not delay the game intense; any 2.4G products will appear in the use of intermittent failure?
A、Outside interference; when a strong external magnetic field, radiated interference, it will largely affect the signal transmission, causing a halt; can be re-connected to the code
B、Impact of the operating system; when the computer is running programs are using too much computer resources, resulting in CPU can process data in a timely manner
C、Check if the battery is fully charged. (Low pressure alarm light will flash)
6、2.4G frequency band higher than a cell phone, and its radiation is not great? Of human beings?
Higher frequency than in mobile phones, but its radiation is very small. Radiation, size is not a single decision by the high and low frequencies, and the transmission power of the size of a great relationship. GSM mobile phone up to the peak transmit power 1W, and 2.4G mouse and keyboard products, the peak transmit power less than one million mobile phones, thus greatly reducing the radiation on the human body
7、2.4G key products have been tapped, the risk of being controlled by others?
2.4G products, strong anti-jamming, frequency in the 2402MHz-2480MHz, sub-16 group of frequency bands, in the two-way transmission mode, if subject to the same frequency interference, it will automatically avoid FM; and each band has a 256 group ID code encrypted strictly
8、Why use laser mouse below the normal light does not shine?
Wavelength of visible light range between 390 ~ 770 nm, conventional laser mice laser wavelength of 850 nm, beyond the naked eye visible range. However, computer camera, cell phone camera when shooting low light level visible red
9、Laser Mouse eye damage it?
When the laser mouse in the production of each product will be strictly controlled in power within the required safety, it is safe to use
10、Optical mice and laser mice What's the difference?
A、Optical Mouse with LED as the engine, the diffuse reflectance imaging (reflectance diffuse to shooting in all directions), in glass, tile and other surfaces can not draw a line; LED long life, low cost, easy to manufacture, is now mainstream
B、Laser mouse laser as the engine, specular reflection imaging, specular reflection patterns can produce greater contrast, the imaging sensors are easier to identify the image, the mouse is more precise positioning; a single wavelength laser, focus is good, reflection intensity LED stronger than almost work on any surface; laser engine with low power consumption, so energy saving compared with LED; but the high cost is high, life expectancy shorter than the LED

20、为什么我买的USB接口的鼠标在WindowsXP以下版本操作系统不能使用?
A、是否有安装其他公司的鼠标驱动程序，若有，请您将它们的软体删除后，重启您的电脑，看问题有没有解决。
B、如果您没有安装其他公司的鼠标驱动软体，请您按照这样的办法操作一次：启动电脑后，首先进入系统的“控制面板”, 打开“系统属性”, 进入到“硬件”下的“设备管理器”, 将“鼠标和其它指针设备”图标下的鼠标驱动程序全部“卸载”后，重启您的电脑即可。
C、在这里，我们再重复一次，我们的“USB”鼠标为何在Windows98系统下不能即插即用，这个问题是因为“USB”鼠标采用不同“USB”接口芯片，在第一次使用时电脑都会要求安装驱动软件，这时您只要按照系统安装提示，让系统自行安装，当系统找不到驱动程序时，您只要每次点击跳过，直到安装完成后，您即可使用您的“USB”鼠标。待下次您再次使用相同的“USB”鼠标时，系统就不会再次要您安装软件，可以实现即插即用了。
D、针对我公司USB接口鼠标，如果客户在WindowsXP以下版操作系统不能使用时，如Windows2000/98/NT等等，可能在第一次插入USB接口时要求驱动程序，只要你选择跳过....跳过...一直选择跳过，最后就可以成功使用。如果你不小心选择错了，请拔出鼠标USB接口，重新来过。
