Operation
Primary touch panel switch operation, battery status and out of beam indication
follow. Secondary switch operation begins on page 19.
Power Switch: Press the power switch on the touch panel to turn
the unit on. All the LED's will light and then each row will light from
top to bottom. The LCD will cycle its symbols. If the receiver is out of
the laser beam, the center green LED will flash and the LCD will be
on to confirm power is on. If the receiver is in a laser beam, a corresponding
LED grade display will be indicated.
Plumb Switch: Three position switch - off, standard, and Angle
Compensation for Excavation (ACE) mode. Plumb indication is generally
used during excavation operations. Press the switch once to change
between standard plumb mode and plumb off. The standard plumb is
preset to a range of ± 2.5°. The LCD will show no plumb symbol when
it is turned off and will show the standard plumb indicator when the standard
plumb mode is selected. The grade indication LED's will flash quickly when the
mast and receiver are extended beyond the plumb range and will flash slowly
when retracted beyond the range. The display will be solid when the mast and
receiver are within the plumb range.
Angle Compensation for Excavation (ACE) mode: The receiver displays
grade information at wide swing angles of ± 10° to 30°. To enter this mode,
press and hold the Plumb Switch for approximately 2 seconds. The on-grade
location will automatically switch to the center on-grade and the wider plumb
angle symbol will appear on the LCD. A single or pair of LED's will be lit. These
LED's correspond to the set-up length that is input using the scale on the front
label of the display area. A set-up procedure is required to compensate for
the dipper arm swing arc. To determine this length and for more installation
information, please refer to the instructions beginning on page 11.

Operation
Center / Offset On-Grade: Center on-grade or "grading mode" is
selected when grade information is useful both above and below
on-grade, as with typical grading operations. Offset on-grade or
"excavator mode" is selected when using a backhoe or excavator.
The excavator mode gives more information and a larger display above on-
grade. Press the switch to cycle between the two options. The LCD will indicate
which mode is selected and the LED's will display the appropriate pattern. The
center on-grade has 7 display channels plus 2 out of beam indications. The
offset on-grade has 8 display channels plus 2 out of beam indications.
Deadband (Accuracy): Four deadbands are available in the grading
and excavating modes. The LCD indicates which mode is selected.
2 deadbands - fine and standard - are available in the angle
compensation (ACE) mode. The smallest deadband is used for receiver
set-up. Selections are then made to fit job requirements. Please refer to
the specifications on page 22 for specific deadbands. To change the deadband,
press the deadband selection switch. The deadband and corresponding LCD
symbol will change and cycle with each press.
