Step 4 • Hold the receiver steady and watch the laser beam. When the on-
grade signal is achieved, the laser is precisely aligned.
•Press the STAR button to apply the axis correction, to quit the appli-
cation and return to the main menu.
Notes • The X and Y-axis return now to the previously entered grade values.
The alignment is electronically compensated; therefore the mechan-
ical alignment of the laser may not be in alignment with the axes.
• In order to indicate that axis alignment is active, the axis alignment
icon appears on the display instead of the remote icon.
• As a control watch the laser beam on your receiver, insure that it is
still centered.
Important • In order to reset the axis alignment correction, select the axis align-
ment dialog and press STAR.
• The axis alignment icon is not shown if the axis alignment correction
is off.
• By turning off the instrument the axis alignment correction is turned
off as well.
• HI alert is disabled during the axis alignment procedure.
Limits and Excep-
tions
• The X- or Y-axis must have less than -3.500% or 13.500% grade.
• The maximum angle of miss-orientation allowed is 5 degrees.
(This represents an offside of 8.7m at 100m).
• The maximum working distance for axis alignment is limited to the
operation of the remote control when used, or the sensor's ability to
receive the laser signal when the remote is not used.
