The Leica Remote Control 739854 works with the Rugby 400DG rotary laser level by Leica. This remote features up to a 200-foot operating range with a six-button keypad and illuminated LCD display that illustrates the rotary laser's settings. With this remote control, you can change the grade of the Rugby 400DG as well as tilt its X or Y axis. The remote offers users a standby function that holds the rotary laser in standby for up to 16 hours before powering off completely. An automatic shut-off feature preserves the remote's battery by powering it off after two minutes of non-use. And when the available battery power declines, the remote's low battery indicator will notify you on the LCD display.
The Leica remote functions on four AAA alkaline batteries.
