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 self-
leveling 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 self-leveling function was
activated 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.
The three lamps blink at the same time
and the rotary head rotates at low speed.
Height alert status
[How to reset]
1
Turn off the power switch.
2
Check whether the instrument is installed
correctly.
3
Turn on the power switch. Self-leveling starts
again. After self-leveling is finished, the laser
beam is emitted.
4
Make sure that the laser beam is set at the
correct height. Then, restart the operation.

A flash and a buzzer sound signifies
that the height alert function of rotating
laser is operating.
Rotating laser battery warning*2
A flash shows that the rotating laser
power is low.
Note: The warning displays *1 and *2 are the functions that the level sensor
detects alarm signal from the rotating laser.
The level sensor can be canceled the alarm detection from the rotating laser.
To be canceled the detection; Press the power switch while pressing the
buzzer sound switch when powering on.
(1) Battery is sufficient.
(2) The power is low, but
laser is still usable.
(3) Dead battery.
Replace the dry battery
with new one.
Aligning Direction of Slope
It is possible to set slope only in the X axis direction (refer to “CHECKS
AND ADJUSTMENTS”).
[1. Installation of the instrument]
When using the laser to set the slope, the laser must be properly
aligned so the slope axis of the laser beam is parallel to the desired
direction of slope.
The sight on top of the instrument is calibrated to the slope axis of the
laser beam. Follow the steps below to align the laser to the desired
direction of slope:
1
Establish a target line parallel to desired direction of slope.
2
Set up the laser over this line (drop a plumb bob from the tripod
mounting screw).
3
Rough align the instrument to the direction of slope. Make sure it is
properly oriented for the slope to be set.
4
Using the sight, position the instrument so the sight is centered on
the target. (see illustration below)
Lamp Position
• When you set the “Manual” mode to ON after setting
the slope, the beam is fixed at the set slope position.
At this time the Slope key does not function.
For information about Manual mode ON/OFF, refer to
“NOMENCLATURE AND FUNCTIONS”.
• Check the beam often during slope use for slope
accuracy. Check instrument calibration periodically.

Checking cone error
Horizontal calibration of the laser beam can be checked by the user.
[Checking]
1
Set up a tripod approx. 50m (160ft) from a wall. Mount the
instrument on the tripod, facing the X1 side toward the wall.
2
Turn the instrument on and allow self-leveling to complete.
3
Put the level sensor in fine detection mode by pressing the On-
Grade precision switch.
4
By using the level sensor, mark the center position of laser beam
on the wall. (X1)
5
Turn off the instrument.
Loosen the tripod screw, rotate the instrument 180 degrees and
re-secure it on the tripod. The X2 side of the instrument faces
toward the wall.
When rotating the instrument, avoid changing the height.
6
Turn the unit on again and allow self-leveling to complete.
7
By using the level sensor, mark the center position of laser beam
on the wall. (X2)
8
If the difference value of marked two laser beam heights
(difference value of X1 and X2) are less than 5mm, adjustments
are not needed.
The difference value is greater than 5mm, adjust the instrument
as described in right.*
9
Check the Y side as the same way.
To discontinue calibration the instrument, press the Power switch.
Perform the following check after completing horizontal calibration procedure.
[Checking]
1
Set up the laser centered between two walls approximately 40m (131ft) apart. Orient the instrument so one axis, either X or Y, is facing the walls.
2
Locate and mark the position of the rotating laser beam on both walls using the level sensor.
3
Turn off the instrument and move the instrument closer to wall A (1m to 2m /3 ft to 6 ft). Do not change the axis orientation of the instrument. Turn the instrument on.
4
Again locate and mark the position of the rotating laser beam on both walls using the level sensor.
5
Measure the distance between the first and second marks on each wall. If the difference between each set of marks is less than 4mm (5/32 of an inch), no error exists.
* If the difference value is greater than 4mm (5/32 inch), contact your local dealer.
