The R800 is a wireless presenter with a brilliant green laser and intuitive slideshow controls that help you make high-impact presentations. It's powerful and easy to see-even on LCD, plasma displays and in brightly lit rooms. Keep track of time, battery power level and wireless reception with a glance or with silent, vibrating alerts so you can remain focused on your presentation, not the clock. You'll enjoy the 30m (100') wireless freedom and a reception-level indicator ensures you don't wander too far. Buttons are easy to find by touch and the smooth contours feel great in your hand. You'll be in control from the first slide to the last.
