Product Manual

Operation
Display Brightness: The brightness switch controls the LED
brightness. Bright, Dim, and Off are the options. Use Dim for normal
and lower light conditions and Bright for sunny daytime operation if
necessary. Display Dim will conserve battery life by approximately
50%. Press the Display Brightness switch to cycle through the three options.
The selection will be indicated on the LCD.
Additional Features
Battery Status Indication: Battery status symbol is depicted on the LCD
when the unit is powered by batteries. Three levels are displayed. The
battery symbol is full when the batteries are good. The battery symbol
is half full and blinking when the batteries are low. The receiver will still
operate for a short period of time. When there is an outline only, the batteries are
drained and must be replaced. The battery symbol outline and the four corner
LED's will flash to indicate the batteries require replacement or charging.
Out of Beam Indication. The LED display will indicate if the receiver has moved
beyond the vertical laser reception range. A sequence of LED's will indicate
which direction the implement must be moved to pick up the beam. The out of
beam indication will continue for approximately two minutes.
Out of Beam Indication Disable: The out of beam indication can be turned off
if desired. Press the two outer switches (Plumb Selection and Brightness) at the
same time to disable. The receiver will display the out of beam LED sequence
in reverse order from both top and bottom. When disabled, the receiver will
indicate out of beam by flashing the center LED. Press the two outer switches
again to enable the indication. The receiver will remember the out of beam
display state at the next power up.

Installation - General
Set up the laser in a convenient, safe location. Please refer to the laser operator's
manual. Ensure the laser is on a stable tripod. On windy days it may be
advisable to tie down the tripod for a more stable laser beam.
Operating distances are dependent upon the rotating laser power. The receiver
can pick up the beam from all directions (360°), but requires a clear line of sight
between the laser and receiver.
If your laser has selectable rotation speeds, select a high rotation speed. The
receiver can process speeds up to 1200 RPM.
To mount the receiver on the mast, turn both the top and bottom knobs
counterclockwise until the mounting clamps in back open enough to fit around
the mounting mast. Place the receiver on the mast. The receiver will mount to
round tubing that has a 1.66" to 2.00" outside diameter (42 to 50 mm) or to
1-1/2" (38 mm) square tubing. Turn the knobs clockwise to tighten. Loosen the
two clamps to remove the receiver from the mast.
For excavation, the receiver may be set up in the trench or above ground.
Please follow all safety precautions per the machines operator's manual and
follow all excavation and trench safety requirements and practices.
Angle Compensation (ACE) mode - the horizontal grade checking width
will be wider as the receiver set-up length is decreased. For example, the
closer the receiver is mounted to the bucket, the wider the grade checking
range will be.
The most accurate and repeatable method for checking grade is with the
bucket cylinder fully retracted. The mast must be mounted so it points to
the bucket teeth in this set-up.
Checking grade with the bucket levelled or other positions provide for faster
rough excavation. The receiver indicates level at the bucket pivot pin in these
positions. It is important to take grade readings only
when the bucket is in the original set-up position.
The LED display must be in the direction of the
operator and be perpendicular to the direction of the
dipper arm swing.
For all excavation operations, always take a sample
reading with the bucket "on-grade" and check to ensure
the elevation is correct.
