The Leica RC400 remote control is designed for use with the Leica Rugby 840 rotary laser level, performing all of the functions of the unit with up to a 200-foot operating range. The RC400's keypad has 12 buttons that change the width of the laser's scanning motion, tilts the X and Y axes, aligns the vertical plane and 90-degree split beam, and changes the direction and speed of the rotary head. The remote also features scan memory which returns the Rugby 840 to its last scanning motion position.
The RC400's sleep mode saves the Rugby's battery, putting it to sleep for two hours before powering off completely. An LED indicator on the remote control flashes whenever it is successfully sending a signal to the rotary laser.
The RC400 remote control runs on just two AA alkaline batteries for a 70-hour battery life.
