OPERATION
How To Operate
4 Press power switch on level
1 Set the instrument to the tripod or smooth
5 Select the precision mode by
surface.
2 Make sure instrument is roughly level.
3 Press power switch (ON).
Height Alert Function
Example Operational
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
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 auto leveling function was
activated and the laser beam was emitted, this function works.
• The height alert function does not work in the "Manual" mode.
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 at right)
Target
CHECKS AND ADJUSTMENTS
1 Checking and adjusting calibration
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 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 auto-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.
* If the difference value is greater than 40mm (±90"), it exceeds the
adjustment range. Please contact your Topcon dealer.

REGULATION
FCC
NOTE:
This equipment has been tested and found to comply with limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interfer-
ence to radio communications.
However, there is no guarantee that interference will not occur in a particular instal-
lation.
If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is encour-
aged to try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
- Consult the dealer or an experienced radio / TV technician for help.

[2. Setting slope]
Operating procedure
(Setting slope)
1 Press Power switch ON.
You can set the slope after auto-leveling is completed.
2 Press one of Slope keys once. The laser beam keeps slop-
ing in the direction of the pressed key.
3 Press the Slope key again. The laser beam stops sloping.
(Unless you press the Slope key again, the laser beam is set
horizontally.)
4 Press the Slope key to adjust the slope. How long you press
the Slope key can change the laser beam sloping speed.
The blinking speed of the lamp provides a visual indication of
the beam movement speed.
5 Press Power switch OFF to cancel the slope setting.
How to set the slope before the power is OFF again
1 To set the slope before the power is OFF again, turn on the Power switch
as pressing either right or left of the Slope keys. The slope is kept and you
can adjust the slope in the same way as Step 4.
(When the Power switch is ON without the Slope key pressed, the laser
beam will return to level.)

Corrective Action
Correct tilt of the instrument until it less than 3 degrees.
Replace the four alkaline dry cell batteries with new ones at a time or charge
the battery pack.
Turn power off, rough level the instrument, then turn power on again. Check
height of laser beam as it may have changed.
Repeat calibration procedure. If error repeats contact your local Topcon dealer.
Push the slope key of the opposite side, and align slope.
Turn power off, then on again. If error repeats contact your local Topcon dealer.

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 Topcon dealer.
