7. Press the keypad calibration axis I button.
Press the keypad rise or lower calibration
beam buttons to raise or lower the laser
beam. Ensure that the beam is exactly
halfway between A and B.
8
. Mark this calibrated point on the vertical
surface, as C.
9. Rotate the tool back 1
8
0° (same position
as step 4). Locate the laser beam on the
same vertical wall. It should coincide with
C. Repeat this step until the beam is at the
height of C.
10. Place the tool with the side marked II
toward the wall. Position the unit such that
Line II is square (90°) to the wall. Mark the
laser beam height on the vertical surface,
as D.
11. Compare the height of C with D. If the
heights match, calibration is complete.
Proceed to step 1
3
. If the heights do not
match, proceed to step 12.
12. Press the calibration axis II button. Press
the keypad raise or lower calibration beam
buttons to raise or lower the laser beam
until it matches the height of C. Calibration
is complete.

. Simultaneously press the keypad
calibration axis I and II buttons. Hold for
three to five seconds, then release when
you hear two beeps, signalling the exit of
calibration mode.
14. Turn off the tool, then turn it back on again
to resume normal operation.

Using the Remote Control / Receiver-Detector
The GRL145HV can also
be operated using the
RCR2 Remote Control /
Receiver. Its receiving
(detecting) function
responds better to the
GRL145HV laser tools
rather than any other laser
receiver-detector. The
RCR2 allows accurate laser
beam detection outdoors or
under other conditions
when the beam is difficult to
see. The following diagram
illustrates the RCR2
remote control.
