Height Alert function
When auto-leveling and height alert function are active, this function prevents
the instrument from operating if it is disturbed. This insures accurate control. If the unit is dis-
turbed, all displays and Auto-leveling lamp will flash. The elevation (height of instrument)
should be verified and re-established if necessary.
To activate the height alert function
To activate the height alert function, depress and hold the Manual key [MANU] while turning
on the instrument by pressing the Power key. The display will show “HiON” for two seconds
before starting auto-leveling. Height alert function will be turned ON automatically after 10
minutes since the auto-leveling is completed.
Turn the power key OFF and ON again, the height alert function will be de-active again.
Note
• The LS-70A and LS-70B laser sensors can detect and signal the height alert
warning.
