The RM2E-3 Rigid Mast is used in machine control applications where changes in the benchmark
elevations are minimal and when manual adjustments of the RT2S Laser Receiver's height do not
present a safety risk.
The Gradio® Display System is capable of operating in temperatures from -20 to 140° F
(-29 to 60° C).
Normal Gradio® Display System operating range (between RT2S Laser Receiver and DR2 Display)
is up to a 100-ft (30.5 m) radius.
The RT2S Laser Receiver is an omnidirectional, 360-degree receiver that accepts signals from the
600-rpm rotating lasers.
The RT2S Laser Receiver translates and sends elevation information to the DR2 Display via low-
power radio communication.
12-/24-Vdc bulbs may be used. To avoid damage to equipment, ensure proper bulb is
installed for machine's electrical system.
Five channels of grade data (high coarse, high fine, on-grade, low fine, and low coarse) are
displayed for the Operator through bright lenses in the DR2 Display.
The RT2S Laser Receiver is a self-contained, battery-powered unit that can be mounted in an
optimum position without concern for cable routing and subsequent cable damage.
The MM2E Manual Mast provides a mount for the RT2S Laser Receiver to slip over and clamp into
The MM2E Manual Mast has increment/decrement mast tape to indicate changes in position of the
MM2E Manual Mast.
The RM2E-3 Rigid Mast has increment/decrement mast tape to indicate changes in position of the
RM2E-3 Rigid Mast.
The RM2E-3 Rigid Mast Quick-Release Pin enables easy removal of the RM2E-3 Rigid Mast from
the mast mount.
The RM2E-3 Rigid Mast Lanyard Chain connects the Quick-Release Pin to the RM2E-3 Rigid Mast
tube to prevent loss when disconnected.
