green laser pointer with good after service
A: hello, only Xin flip pen used to meet international safety standards of Class Ⅱ laser module, the use of advanced automatic power control APC technology, more power. Charge can use 1-3 months. Mainly depends on your frequency of use. Q: I tried on a laptop: plug the receiver automatically installed the drivers, you can use. But that is a black key on a laptop as I tried: the receiver automatically installed the drivers plug in, you can use. People should buy a green laser pointer with perfect stability.Appeared Sogou input method "appeared Sogou input method" bbb ...." A: black is black ppt full-screen mode, press the shortcut key to achieve, then the English input method also requires state Q: There is no other kind can control the player TTPlayer flip pen? I have to switch the appropriate time during the meeting is there any other kind you can control the player TTPlayer flip pen? music, do not look the computer can directly switch to the next the first, including reducing the volume to increase the music, do not look at the computer can switch directly next song, including reducing the volume increase. A: vp600, LP05 can be achieved. flip it? can control of other software other software? Q: PPT page can only control it? People should buy a led flash light with good after service.Ability to control other software? products in the page when the page on the keyboard function keys and Page Up and Page Down functions are the same, use The technology is also the same. by wireless presenter on the flip key, and press the page button on the computer keyboard, the effect is the same. can use the keyboard on the next page Page Up and Page Down keys control documents, promise The page for the Wireless Presenter page control keys can be realized for example in Word, Excel, browser IE, plug-in software ACDSee inside, can be achieved, the next flip operation if you use the software to customize the fast key, you can define shortcut keys via the page key to achieve remote operation. technology is the difference? Q: Infrared IR and radio frequency RF technology is the difference?Select the green laser pointer by checking if the receiver of it contacts well. A: Infrared IR and RF is the RF flip pen two different remote control technology. the use of infrared technology, product direction, the transmitter must align the receiver, and no intervening obstructions. distance is not more than 7 meters from electromagnetic interference, the advantages of infrared products are low cost products, the price cheap. using radio frequency technology products are used radio waves to transmit control signals, and its directional characteristics, can not "face to face" control, distance, up to tens of meters. between the transmitter and the receiver can be as long as there is no from the shielding effect of the metal barrier material, can be used normally. When select a green laser pointer, remember to test how far it can remote control practically.RF technology of the product cost is usually higher, but no direction, more convenient, more so by the users. CD Xin laser pointer is used in most RF technology mean? Q: 2.4GHz 315MHz 433MHz What does it mean? 2.4GHz RF technology is referred to a working band, 2.4GHz ISM (Industry Science Medicine) is the world's free open wireless spectrum in the 2.4 GHz band can get to work more anti-jamming capability, and because transmission power is small, more suitable for battery-powered products.
