XP systems. So throw away that old clunky keyboard, free up valuable desk space and put an end to sticky keys. Please take a few minutes to review the simple operating instructions in order to get the most out of your keyboard. General Production Description The Virtual Keyboard is a miniature, stand-alone accessory that emulates the function of a standard, full-sized keyboard. The Virtual Keyboard can connect via Bluetooth to almost any information appliance, including: PCs, Tablet PCs, Laptops, PDAs and Smartphones, with the use of an appropriate driver. Laser Safety Precaution The Virtual Keyboard device emits two laser beams. One beam (red) projects the keyboard image, and the other beam (invisible) is used for sensing which keys have been touched. The radiation levels of both laser beams do not exceed the Accessible Emission Limits of Class 1, as defined by the international standard IEC 60825-1 (A2) and the American standard 21 CFR 1040.10. The Virtual Keyboard device is, therefore, a "Class 1 Laser product". This means that the Virtual Keyboard device is safe under reasonably foreseeable conditions of operation. Although the emitted laser beams are safe (as defined by the above standard), it is highly recommended not to stare directly into laser beams. 4 Disclaimer The manufacturer shall not be liable for errors contained herein or for incidental or consequential damages in connection with the furnishing, performance or use of this material.
