Calibration
Calibration needs to be done prior to the first use.
If the measurement
rail is ever removed from the wall and moved to a different wall location, it
will need to be done again. The height rod retains calibration during battery
changes.
Use care and recheck your work as calibration is the key factor in the
accuracy of the height rod.
1. Using a quality tape measure, make a pencil mark on the side of the
measurement rail 39-3/8” (100.0 cm) from the floor. Check your mark to
make sure it is correct.
2. Turn on by pressing and releasing the on/off button. A flashing “Strt” will
display.
3. Press and hold the on/off button for 7 seconds until flashing “r100”
displays. Release the button.

39-3/8” mark
4. Lower the headpiece until its bottom silver surface is even with the 39-3/8”
pencil mark you made in Step 1. While holding the headpiece even with the
mark, press and release the on/off button. “100.0” will now be flashing on
the display.
