Зеленая лазерная указка

II.Function Description 1. Laser pointer with RF wireless control is a new patent product designed specifically for computers and multimedia projectors. In addition to the traditional usage of laser pointer, it also has the novel function of turning the pages displayed on the screen of the computer up and down by simply clicking the PageDown and PageUp buttons via wireless control. Now teachers and lecturers no longer need to stay beside their computers,they can walk freely in the classrooms or meeting halls, with near distance and more interaction with the audiences. Pages could be turned freely and silently, and highlight effects can be obtained in their presentations. III. Product Features 2.Built-in laser pointer with PageDown/PageUp buttons. Pressing and releasing the PageDown/PageUp buttons are equivalent to hitting the PageDown/PageUp keys in the computer's keyboard. 3.RF wireless link. No necessary to point the pointer to the receiver. 4.The pointer only needs one AAA size battery. New power saving technique is taken to prolong the battery's life. 5.USB1.1 interface, plug and play, automatically code study and easy to use. 6.Pretty small receiver, Human Factor Engineering considerations for long time use. 7.Advanced RF design, very low level emission, which is green, health and environment protecting. IV.Tech-Specification Frequency: 315MHz/433MHz Modulation:ASK ID codes:one millon Code study: auto Operation range: 7-10 meters 2 Emission power: < 5mW Laser wavelength: 650 nm Laser power: < 2mW Battery : 1 AAA size battery 1 Receiver power: USB afford Receiver interface: USB1.1 Operating system: Windows V. Installation & Usage Plug the receiver into the USB port. The receiver's LED will flash several seconds,meanwhile, clicking the PageDown/Up buttons of laser pointer ,it'll stop flash , that means start the code study , then ready to work. VI. Study-Key Function 1. Pressing about 8 seconds, till Light button off, means delete all memory. 2.After that,press smoothly,then light button on,means start memory.Meanwhile,Press the Up or Down smoothly, the receiver'll flash ,it means the code-study is successful. At this time, Receiver & Laser Pointer is one-to-one connected, no other pointer will make this receiver works. 3. If needs the receiver being remote-controlled by other laser pointer, press Study Key smoothly,while Light button flashes,press the Up-or-Down Key,then will see receiver Light button flash,that means it works.

The normal operating time of this product will be related to the using frequentness of the laser. 4. When installing the USB receiver in a Window98 system, it is probable that a Win98 built-in USB keyboard driver should be installed, following the instructions prompted by Win98.
