Height Alert function
When auto-leveling and height alert function re active, this function prevents the instrument
from operating if it is disturbed. This insures accurate control. If the unit is disturbed, all dis-
plays and Auto-leveling lamp will flash. The elevation (height of instrument) should be verified
and re-established if necessary.

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.
