The Targus Laser Presentation Remote features a clear & intuitive button layout, making it easy to give presentations. Thanks to its 2.4 G Hz cordless technology, you'll be free to move around & control your Microsoft Power Point or Apple Keynote presentation remotely, without wires & cords getting in the way. The patent-pending Key Lock 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 RF 2.4 G Hz cordless technology works from up to 15 meters away, providing flexibility while presenting in large conference rooms or classrooms. The mini USB (Universal Serial Bus) receiver stores neatly inside the remote when it's not in use for added convenience, so it won't get lost or damaged. There's no need to worry about losing power part-way through your presentation. Should your AAA Energizer MAX battery run out, there is a back-up battery compartment where you can store a spare battery. Both stylish & functional, the Targus Presentation Remote is your essential tool in achieving seamless presentation results.
