Grade Display
Five channels for grade information show when the blade/cutting edge is on-grade or
needs adjusting. The LEDs form directional arrows that show whether to move the
blade/cutting edge up or down.
Out-Of-Level Warning
The out-of-level (OOL) warning is used with lasers that can indicate that they are out
of level by changing their rotation speed. The factory default setting is for the warning
to be off.
To activate the out-of-level warning, turn the receiver on. Press and hold the power
button then press and release the brightness button. An “X” pattern flashes and
the center green LED lights to confirm that the warning is on. Pressing the button
combination again while the “X” pattern is lit, allows you to toggle between having
this function turned on and off. When the center green LED is not lit, the warning
is off.
When the warning is turned on and the laser drops to 300 RPM, a flashing “X”
pattern appears on the display to indicate that the laser is out of level.
Beam Averaging
The beam-averaging function senses the laser strikes and applies the highest level of
averaging appropriate for the laser rotation speed. Averaging stabilizes the LED display
in unstable laser setups, such as windy conditions or long-range applications. The
factory default setting is for beam averaging to be on. The beam-averaging function
can also be turned off. When the function is off, the receiver processes and displays
each laser strike.
To change between having this function turned on or off, press and hold the power
button then press and release the deadband button. The outer green on-grade LEDs
flash to indicate that averaging is selected. When the center LED is on, averaging is
on. When the center LED is off, averaging is off. Pressing this button combination
while the LEDs are activated changes the current selection between on and off.

Installation
1. Position the machine so the blade or bucket can be set to the desired finished
elevation (typically on a benchmark or hub stake).
Note: When an excavator or backhoe is being used, the dipper arm should be
vertical or near vertical, and the bucket positioned so that it can easily be put in
the same position each time a grade reading is taken.
2. Set up the laser in an appropriate location for receiver visibility and efficient
machine operation. Turn on the laser.
3. Turn on the receiver.
4. Slide the receiver up or down along the length of the mounting pipe to make sure
that the laser beam intersects the pipe where the receiver will be mounted.
Note: Ideally you should be able to move the receiver far enough in either direction
to use the entire reception range (receiving all the grade displays and out-of-beam
indicators). Adjusting the height of the laser may be necessary.
5. Turn the top and bottom mounting knobs counterclockwise until the mounting
clamps in the back of the receiver open enough to fit around the mounting pipe.
6. Place the receiver on the pipe. Move the receiver up or down until the on-grade
LEDs light.
7. Turn the knobs clockwise to tighten the clamps. Do not mount the receiver on
painted poles. Paint can accumulate on the clamps and deteriorate the clamps’
gripping capacity.
Note: When the receiver is mounted to a bulldozer, motorgrader, scraper, or other
grading machine, keep the blade at the proper elevation by manually controlling
the blade so that the receiver stays within on-grade range. The LEDs show which
direction the blade needs moving to be on grade.
Note: When the receiver is mounted to an excavator or backhoe, the receiver
is a grade checker and allows the depth of cut to be monitored from the cab of
the machine. To check grade, put the dipper arm in the vertical position and the
bucket in the setup position. Touch the bucket to the bottom of the ditch.

Warranty
Trimble warrants the receiver to be free of defects in material and workmanship for a
period of two years.
Trimble or its authorized service center will repair or replace, at its option, any
defective part for which notice has been given during the warranty period. If required,
travel and per diem expenses to and from the place where repairs are made will be

any implied warranty merchantability of fitness for a particular purpose, are hereby
disclaimed. This warranty is in lieu of all other warranties, expressed or implied.
Out-of-Beam Indication
The receiver has an out-of-beam (OOB) function. When it is turned on, the LED
grade display indicates that the receiver has moved beyond the vertical laser reception
range. A sequence of LEDs indicates which direction to move the blade or cutting
edge to pick up the laser beam. If the receiver is above the beam, move the edge down.
If the receiver is below the beam, move the edge up. The sequence stops as soon as a
laser signal is received. Otherwise, the function shuts off after two minutes.
The factory default setting is for the out-of-beam function to be on. The LED display
sequences inward toward on-grade to indicate that the function is on. To turn the
function off, press the two outside buttons (Unmarked Buttons) at the same time. The
LED display sequences outward from on-grade to indicate that the function is off.
