The CB420 is a rugged CAN based, operator interface for dual laser based machine control systems. Simple operation with toggle and push button switches gets you to grade fast and accurately. Dual LED grade displays relay the blade position to grade in day or night lighting condition to maximize productivity. The grade display automatically compensates for varying light conditions to ensure comfortable viewing. A graphical back lighted LCD provides numeric elevation and system configuration information with easy to read graphics. The backlight LCD is temperature compensated to maintain sharp contrast regardless of the weather. A built in beeper provide the operator audible tones to grade errors, switch activation, and system heath. This device is designed to be mounted in the cab while in operation, and be quickly removed for storage when not in use.

6. LR400 Linear Laser Receiver
Key Features
Combined laser detector and grade display unit
Linear Receiver – Accurate over the full detection range
