Calibration
Re-calibration can be performed as described below.
1. Use a level to mark a horizontal reference line on the wall.
2. Power on the unit to compare the projected horizontal line with
its references. Compensator has to be locked before
making calibration adjustments. If it tilts, remove the side
plastic screw/plug and use an allen wrench to calibrate the
unit through its side calibration hole. Rotate the allen
wrench clockwise when the horizontal line tilts right. Rotate
the allen wrench counter-clockwise when the horizontal line
tilts to the left.
3. If the horizontal line is too low or too high, carefully
disassemble the window frame by removing the outer plastic
screw/plug and the inner metal screw. Use an allen wrench
to calibrate the adjustment screws located between the
glass prisms. Rotate the allen wrench clockwise when the
horizontal line is too low. Rotate the allen wrench counter-
clockwise when the horizontal line is too high. Reassemble
the window frame after completing the calibration.
