STORAGE PRECAUTIONS
1
Remove the battery cover by turning battery cover knob to “OPEN” side.
2
Remove the batteries by pulling out the slide plate.
3
Install the new batteries referring to the illustration on the battery
cover.*1, *2, *3
4
Install the battery cover. By using a coin, tighten the battery cover knob
to “CLOSE” side until the knob does not turn.*4
*1 Replace all 4 batteries with new ones at the same time. Do not mix used and new batteries,
and do not mix different types of batteries together.
*2 Use alkaline dry cells. (Dry cells for movement con
fi
rmation are packed in shipment.)
Nickel hydrogen dry cells and nickel cadmium dry cells can be used too, but the operating time
is different from the time of alkaline dry cells.
*3 Generally, performances of dry cell deteriorate temporarily in low temperature, but recover in
normal temperature.
*4 It is important to use a coin or other tool to make sure cover is
fi
rmly closed to seal out water.

1
Press the lid in the direction of the arrow to lift.
2
Remove the battery and replace with a new 9v alkaline
battery.
3
Press the lid down and click to close.
Laser Sensor
1
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 auto-leveling to complete.
3
Put the laser sensor in
fi
ne detection mode by pressing the On-Grade
precision switch.
4
By using the laser 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 auto-leveling to complete.
7
By using the laser 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 X1 (handle) side as the same way.

X2
[To calibrate the X axis ]
1
Face the X1 side of the instrument (panel side) toward a wall, press the Power
switch while pressing the height alert OFF switch.
Then the height alert OFF lamp will light, and manual mode ON lamp will blink.
2
Press the height alert OFF switch to calibrate the X axis. The manual mode
ON lamp will light. When auto-leveling
fi
nishes, the laser beam will emit.
3
Using the laser sensor, mark the on-grade height of laser beam on a wall.
4
Rotate the instrument 180 degrees to face X2 side toward a wall.
5
In the same way as step
3
, mark the on-grade height of laser beam on a wall.
6
By pressing the manual mode ON switch (laser beam moves up), or Power
switch (laser beam moves down), adjust the on-grade height of the beam until
it is precisely centered between the marks made in steps
3
and
5
.
7
Press the height alert OFF switch to memorize the new laser beam calibration.
The height alert OFF lamp will blink. Power will shut off automatically when the
calibration memorization is complete.
[To calibrate the Y axis ]
1
Face the Y1 side of the instrument (handle side) toward a wall, press the
Power switch while pressing the height alert OFF switch.
Then the height alert OFF lamp will light, and manual mode ON lamp will blink.
2
Press the Power switch again. The auto leveling lamp will light.
3
Press the height alert OFF switch to calibrate the Y axis. The auto leveling
lamp will light.
4
Using the laser sensor, mark the on-grade height of laser beam on a wall.
5
Rotate the instrument 180 degrees to face Y2 side toward a wall.
6
In the same way as step
4
, mark the on-grade height of laser beam on a wall.
7
By pressing the manual mode ON switch (laser beam moves up), or Power
switch (laser beam moves down), adjust the on-grade height of the beam until
it is precisely centered between the marks made in steps
4
and
6
.
8
Press the height alert OFF switch to memorize the new laser beam calibration.
The height alert OFF lamp will blink. Power will shut off automatically when the
calibration memorization is complete.
*If the difference value is greater than 60mm (2 3/8 inches),
contact your Topcon dealer.

[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 laser 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 laser sensor.
5
Measure the distance between the
fi
rst 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.
Perform the following check after completing horizontal calibration procedure.
