The Targus Laser Presentation Remote features a simplistic button layout, making it easy to give presentations. The patent-pending KeyLock™ Technology locks non-essential buttons when not needed to help eliminate accidental button presses. The integrated laser pointer allows the presenter to highlight important content while the backlit buttons provide visibility in environments with low lighting. The latest RF 2.4GHz cordless technology works from up to 50ft away, providing flexibility while presenting in large conference rooms or classrooms. The mini USB receiver stores inside of the presenter so it's always ready to use, while the back-up battery compartment stores an emergency battery so users are always equipped to present. The device is immediately ready to use and comes stocked with high-quality AAA Energizer® MAX® batteries. Both stylish and functional, the Targus Presentation Remote is easy to operate for seamless presentations at work or school. Compatibility Microsoft Windows® 2000, Microsoft Windows® XP, Microsoft Windows Vista®, Microsoft Windows® 7, Mac OS® X 10.4 or later **Please be advised that new Targus product should arrive in sealed retail packaging as shown in the image gallery.
