Building on the elegant modularity of the existing system, the new components provide even more flexibility and configuration options. Compatibility with the Wireless Remote Control, the ARRI Lens Data System and many film and video cameras makes the new Wireless Remote System into the most feature rich system available. New WRS is equipped with a battery capacity display, an illuminated frequency selector and safely recessed control buttons. The focus control has been outfitted with an adjustable index marker and the zoom knob has been repositioned to be just where the thumb expects it. And through the clean and elegant geometry of the modular components the system can be used equally well in either hand.
