Height Alert function
When auto-leveling is active, this function prevents the instrument from operating if it is dis-
turbed. This serves as a reminder to the user that to insure accurate control, the height of the
beam should be re-checked after the unit has been disturbed.
1
To activate the Height Alert function, depress and
hold the left Alignment control pad (see page 10) on
the control panel while turning on the instrument by
pressing the Power control pad. The three LEDs
(Leveling, Manual, Battery) will flash at the same time
for three seconds.
2
When this function is active and the unit is disturbed,
three visible LEDs will rapidly flash.
3
To re-activate auto-leveling and check the beam height, turn the unit off, then on again by
pressing the Power control pad twice. After auto-leveling is complete, check the beam
height to confirm it has not changed.
4
The Height Alert function is now inactive. To re-activate, turn unit off and repeat step 1.
