How To Operate
Example Operational Height Alert Function
When the instrument system detects a shock, this function informs the
operator of it.
• When the instrument's installation status (height) is sharply changed
by the contact of the operator or the like, this function stops auto lev-
eling to keep the operation accuracy and informs the operator of the
situation. The three lamps blink at the same time as shown at the
right.
• After 1 minute has passed since the auto leveling function was acti-
vated and the laser beam was emitted, this function works.
• The height alert function does not work in the "Manual" mode.
Shock is given to
the instrument. Height alert status
[How to reset]
1Turn off the power switch.
2Check whether the instrument is installed correctly.
3Turn on the power switch. Auto leveling starts again. After auto lev-
eling is finished, the laser beam is emitted.
4Make sure that the laser beam is set at the correct height. Then,
restart the operation.
The three lamps blink at the same time and
the rotary head rotates at low speed.
