Height Alert function
When auto-leveling and height alert function are active, this function prevents the instrument from
operating if it is disturbed (after the laser beam emits for one minute). This helps insures accurate
control. If the height or inclination of the instrument changes, the height of instrument should be
verified and re-established if necessary.
1
To activate the Height Alert function, depress and
hold the left Alignment control key (see page 11) on
the control panel while turning on the instrument by
pressing the Power control key. The three LEDs
(Leveling, Manual, Low battery alert) 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 key 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.
