Entering a Grade The grade range is from +40% to -10%. Grade can be set in increments as small as .001% using the digit select or rolling counter entry method. The display lights when entering grade. The LCD is color coded to match the grade entry button: green for positive grade and red for negative grade. -
Page 9: Remote Control And Line Adjustment (Azimuth)
Remote Control Overview The remote is used primarily to move the beam left or right, within the azimuth range, and to put the laser in standby or locked modes. Since it’s an infrared line-of-sight device, there should be no obstructions between it and the laser. It can be pointed at either the front side (through the pipe) or the back side of the laser. -
