Power: Press the power switch on the touch panel to turn the unit
on. All the LED's will light briefly and then each LED row will light
from top to bottom. This also acts as a check to assure the display
is working properly. On-grade location and deadband settings are retained from the last time the unit was turned off. If the receiver is out of the
laser beam, the center light will flash to confirm power is on. If the receiver
is in the laser beam, the corresponding LED grade display will be
indicated. To turn the power off, press and hold the power key for
approximately 2 seconds until the LED's are lit, then release the switch.
Laser Out-of-Level Switch: Used with rotating lasers that change
their RPM's when out-of-level. This function is always disabled
(off). Pressing this switch once turns the function on. The LED
array will display an "X" to confirm it is enabled. When out of the laser beam,
the "X" will flash. When beam strikes greater than 140 RPM are received,
it operates normally. When beam strikes less than 140 RPM are received,
it will toggle between an "X" and the appropriate grade display. To turn the
function off, press the switch again, and an "X" without the center LED will
display indicating the function is disabled.

Center / Offset On-Grade Switch: Center on-grade is selected
for typical grading or cut/fill operations. This mode indicates an
equal amount of grade information above and below on-grade.
Offset on-grade is selected when using a backhoe or excavator.
The excavation mode gives more information and a larger display area
above on-grade. This mode also enables the plumb indication which
shows the operator when the mast and receiver are perpendicular to the
ground (plumb) for more accurate grade readings. Pressing the switch
once lights the LED of the current selection. Pressing the switch again
while the LED is on changes the selection.

Plumb Indication: The plumb indication shows when the mast and
receiver are perpendicular to the ground or beyond the deadband range
of +/- 2.5 degrees. The LED's will flash quickly when the boom is extended,
and will flash slowly when the boom is retracted beyond this range. The
LED display is solid when the boom is within the plumb range.
Deadband (Accuracy) Switch: Two choices are fine and standard
in the grading mode and standard and wide in the excavating
mode. The LEDs are used to show current selection. This selection and the center / offset on-grade selection will determine the
deadband. Pressing the switch once lights an LED of the current selection. Pressing the switch again while the LED is on changes the selection.

Installation - General
Display Brightness Switch: Selects the LED display brightness. Bright and Dim 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%. When the switch is pressed with the receiver out
of the laser beam, the LED's will display a circle with the current setting.
Depress the brightness switch again while the LED's are lit to change the
setting. When receiving a laser beam, simply press the switch and the
setting will change. Viewing the LED's directly in front of the receiver
optimizes the brightness.
Set up the laser in a convenient, safe location. Please refer to your laser
operator's manual. Ensure the laser is on a stable tripod. On windy, gusty
days it may be advisable to tie down or weigh down the tripod to make the
laser beam more stable.
Out of Beam Indication. The LED display will indicate if the receiver has
moved beyond the vertical reception range. A sequence of LED's will
indicate which direction the cutting edge must be moved to pick up the
beam. The out of beam indication will turn off in approximately two minutes
if no beam is received.
Operating distances are dependent upon the rotating laser power. The
receiver can pick up the beam from all directions (360°), but still 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 a 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.
WARNING: Follow all safety precautions per the machines
operator's manual and follow all excavation and trench safety
requirements and practices.

Low Battery Indicator: The receiver has a low battery warning LED
that is used when batteries are installed. During normal operation
with good batteries, the LED is off. When the batteries become low,
the LED will begin to flash. The unit will operate as normal with
approximately 90 minutes of battery life remaining. When the batteries are
too low to operate, the LED will be on continuously and the four corner
grade display LED's will toggle on and off indicating the batteries must be
replaced or charged if using Ni-MH batteries.

When using on an excavator or backhoe, the dipperstick should be vertical
and the bucket positioned so it can easily be repeated each time a grade
reading is taken. The bucket can be fully extended, curled, or levelled, as
long as it is consistent when grade readings are taken. The receiver can
be set-up in the trench or out of the trench if the cut elevation can be
Finished Elevation
Position the machine so the blade is set to the desired finished elevation,
typically on a benchmark or hub stake.
Set the laser up in an appropriate location for receiver visibility and efficient
machine operation and turn it on.
Turn the receiver on, select center on-grade (grading mode) and select
the smallest deadband.
Mount the receiver to the mast.
Slide the receiver up or down until on-grade is indicated. It may be
necessary to adjust the height of the laser.
Alternatively, if the height of instrument (laser beam) to finished elevation
length is known, the receiver can be set by measuring this distance from
the cutting edge of the blade to the center on-grade mark on the back of
the receiver label.
Face the LED grade display toward the operator and tighten the clamps.
Select the desired deadband and brightness.
The LED grade display will direct the operator which way to move the blade
using the machine's controls to maintain an "on-grade" reading.
Make a sample pass with the blade "on-grade" and check to ensure the
elevation is correct.
In Trench Set-Up
Position the machine and dig to the desired finished elevation.
Position the bucket in the grade checking position at the finished elevation.
Set the laser up in an appropriate location for receiver visibility and efficient
machine operation and turn it on.
Mount the mast on the side of the dipper arm.
Turn the receiver on and select the offset on-grade and the smallest
Place the receiver on the mast, tighten, and adjust the dipper arm so the
receiver is within the plumb range - solid LED's.
Slide the receiver up or down to get an on-grade display then tighten.
(The center on-grade location may be selected and set at this time).
Select the desired deadband and begin to excavate.
Take grade readings with the bucket in the grade checking position and
the LED's solid.
Take a sample reading with the bucket "on-grade" and check to ensure
the elevation is correct.
Installation - Excavating
Installation - Magnetic Mount
For excavators and backhoes, determine where the mount
will be located on the machine so that when the BULLSEYE
is attached, it will intersect the laser beam. Ensure the
area of the machine is clean and free of oil and grease.
Angle the mount so the top edge of the top magnet will be
positioned first. Holding the mount by the pipe with both
hands, place the top edge of the magnet on the machine.
Slowly move the bottom magnet towards the machine so
the mount remains plumb.
CAUTION: Strong magnetic field; Do not position fingers next to magnets.
Out of Trench Set-Up
Set the laser up in an appropriate location for receiver visibility and efficient
machine operation and turn it on.
Place the bucket in the grade checking position and situate the machine
so a measurement can safely be obtained on the dipper arm. The dipper
arm may be set more horizontal to the ground for convenient measurements if necessary.
Determine the distance from the laser to the bottom of the trench (L). This
is the set-up length. The length is the height of the instrument (HI) plus the
depth of cut from the benchmark to the bottom of the trench (C).
Mount the mast on the side of the dipper arm.
Position the receiver so the set-up length (L) is the distance from the
bucket ground contact point to the offset on-grade symbol on the back
label. (Set up to center on-grade symbol if center on-grade will be used).
Turn the receiver on and select offset on-grade and the desired deadband.
(Select center on-grade if set to center symbol).
Attach and set-up the BULLSEYE in the normal manner as described on
the previous pages.
Remove the receiver from the mounting pole prior to removing the
magnetic mount. Use a scrap piece of wood or other long material as a
pry bar. Insert the pry bar in between the magnetic mount pole and the
machine. Pry the mount sideways to loosen the magnetic hold. Once the
magnetic hold is loosened, the mount can be easily taken off the machine
by hand.
NOTE: For extendable dipper arms - if the mast is mounted
to the dipper arm section that moves with the bucket, grade
can be checked with the dipper arm extended to any
position. If the mast is mounted to the dipper arm section that does not
move with the bucket, grade can only be checked when the dipper arm is
in the exact set-up position.
Begin to excavate. Take grade readings with the bucket in the grade
checking position and the LED's solid.
Take a sample reading with the bucket "on-grade" and check to ensure
the elevation is correct.
