Operation
Display Brightness Switch: Selects the LED display bright-
ness. 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.
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.
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.

Installation - General
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.
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.
