SERVICE BULLETIN
April 9, 2007
TO: ALL AGATEC SERVICE CENTERS
SUBJECT: LT200 / LT300 Operator’s Manuals – INFORMATION ONLY
This memo is not only re: the owner’s manuals, but also to make you aware of a spec correction.
LT300 brochure spec correction:
The brochure for the LT200 and LT300 printed Oct., 2006 has incorrect information in the LT300
specifications chart.
The specs state that the LT300 has manual grade (or slope match) in both X & Y axes. This is
correct.
It also states that in semi-automatic mode, X is manual and Y is automatic. This is incorrect - the
axes are wrong.
In the semi-automatic mode on the LT300, Y is manual and X is automatic.
The LT200 and LT300 are NOT the same. The LT200 has the opposite axis as self-leveling.
LT200 and LT300 new owner’s manuals
The attached manuals show the new receivers and have a number of other corrections. They
replace the manuals from July 2005.
If any of your customers have trouble calibrating these lasers (including older units), be sure that
they have the latest instructions dated 3/2007.
LT300 without semi-automatic slope match
Not to complicate matters, but…..as of about a month ago, there still were new LT300 units at
AGL which do not have the semi-automatic mode. They are black and silver. The latest models in
dark blue and silver have the semi-automatic mode. I ran off a small supply of different owner’s
manuals for the units without that function.

How To Use The LT200
Setup
Horizontal
The laser can be used on a 5/8-11 tripod, on a wall mount, or directly on a
solid, stable surface.
The LT200 has a wide self-leveling range; however, if the laser is set up out
of the leveling range, laser beam will continue to blink and rotation will not
start.
Turning On the Laser
Turn on the laser with the On / Off key (3). It does a self-test and the beam
blinks while the laser is self-leveling. After it’s levelled, the head rotates.
H.I. Alert
H.I. (height of instrument) Alert stops the laser automatically if the laser is
disturbed or moved, preventing inaccurate readings.
It will function only when selected. To activate this safeguard feature, press
the H.I. Alert key (1). The LED indicator (3) will blink rapidly while the
laser is self-leveling
About 30 seconds after the head starts to rotate, the LED will blink slowly,
indicating the H.I. Alert is activated.
If the laser is disturbed while in H.I. Alert mode, the head will stop rotating, the
beam will turn off, and the LED will stay on.
To start the laser rotating again, press On/Off twice.
Check to see if the beam elevation has changed from its original benchmark
position.
The laser is no longer in H.I. Alert mode. Press key (1) to return to H.I. Alert.
It is important to check while you're using the laser that it has not
been moved and that your setting is still accurate.

a) With detector, mark center of the beam (-Y).
b) Rotate laser 180° so +Y is facing wall.
c) With detector, mark the center of the beam (+Y).
d) At 30 m, the two marks should be no more than 4 mm apart.
If the marks are close enough, Y axis is within calibration; proceed
to Step 10.
9) If not, the laser must be calibrated to bring the beam to the center
of the two Y marks. Use the
∧ or ∨ ARROW keys on the remote or
laser keypad to move beam up or down to the center.
10) Final X to Y check: compare X to Y axes to be sure that your adjusted

time; the marks for X, Y, X, Y should not be more than 4 mm apart.
11) Press the key on the remote with the small dot to save the calibration
(or press the Auto/Man key on the laser)
If you are not sure of the calibration and do not wish to save it, do not press the
small dot, and turn the laser off with the On/Off key.
Checking and Adjusting the LT200
THIS CHAPTER IS VERY IMPORTANT: Here are a few simple
instructions to check your laser for calibration. Remember that the
laser is a precision instrument and it is important that you keep it
calibrated and in proper condition. The accuracy of your work is
completely your responsibility and you should regularly check your
instrument, especially prior to important jobs.
How to Check and Calibrate
The laser has 2 horizontal axes: X and Y .
Each axis must be checked for calibration. If needed, the axis can be
calibrated, carefully following the instructions. You may also take the laser
to a service center for calibration.
Check and calibrate in this order:
Check both sides of X axis.
• If X is within spec, proceed to check both sides of Y.
• If X needs calibration, calibrate X.
Check both sides of Y axis.
• If Y is within spec, proceed to final X to Y check
• If Y needs calibration, calibrate Y; proceed to X to Y check
Final X to Y check: compare +X, -Y, -X, +Y

Calibration Overview
Calibration is electronic, using the optional detector/remote control or the
small remote control (preferred method).
If you do not have a remote, the laser keypad may also be used. This
method will take longer due to the laser making self-adjustments
during movement. Be very careful not to jar or move the laser when
pushing the laser keys, or your calibration will not be accurate.
Fast/Slow Blinking
When in calibration mode, the X or Y LED on the laser keypad should blink
slowly.
When the laser is self-leveling or making an adjustment, the LED will blink
rapidly. Wait until the LED blinks slowly again before proceeding.
Moving the Beam to Calibrate
When pressing an arrow key to move the beam up or down to reach
proper calibration, use short, rapid clicks. Do not hold the key down.
After pressing the key, the LED will blink rapidly as the laser reacts. Wait
until the LED returns to a slow blink to proceed.
If the +X or +Y axis is toward the wall with the marks, use the
∧ key to raise
beam, and the
∨ key to lower beam. If the –X or -Y axis is toward the wall,
it’s the opposite: use the
∨ key to raise the beam and the ∧ key to lower the
beam.

(in calibration mode)
If using a TL25 remote
control, keys with the same
symbols perform the same functions.
Use arrows to move
beam up or down
to reach proper
calibration.
Checking & Calibrating X & Y Axes
1) Place the laser on a flat surface or tripod 30 m away from a wall. If too
bright to see the beam, use a detector with a pole or grade rod.
Position so that -X is facing the wall (this is the side of the laser with the
On/Off key).
Use the sighting groove on top of the instrument for alignment.
2) Hold ROTATION key. While holding, momentarily press the ON key.
Look for:
Y LED flashes, then X LED flashes. Release rotation key.
X LED will blink rapidly, indicating leveling. When the LED blinks
slowly, the laser is ready to verify X axis calibration.
3) To rotate laser beam: Press SCAN key on the remote (or press the
rotation key on the laser keypad).
4) Check X calibration:
a) With detector, mark center of the beam (-X).
b) Rotate laser 180° so +X is facing wall or pole.
c) With detector, mark center of the beam (+X).
d) At 30 m, the two marks should be no more than 4 mm apart.
If the marks are close enough, X axis is within calibration; proceed to
Step 6.
5) If not, the laser must be calibrated to bring the beam to the center of the
two X marks. Use the
∧ or ∨ ARROW keys on the remote (preferred) or
laser keypad to move beam up or down to the center.
Note: With the arrow keys, make small inputs: one click, two clicks, three
clicks, etc. Do NOT hold key down.
6) After calibrating X, check Y. Rotate laser 90° degrees so that -Y is facing
the wall (this is the side of the laser with the keypad).

Calibration Overview
Calibration is electronic, using the optional detector/remote control or the
small remote control (preferred method).
If you do not have a remote, the laser keypad may also be used. This
method will take longer due to the laser making self-adjustments
during movement. Be very careful not to jar or move the laser when
pushing the laser keys, or your calibration will not be accurate.
Fast/Slow Blinking
When in calibration mode, the X or Y LED on the laser keypad should blink
slowly.
When the laser is self-leveling or making an adjustment, the LED will blink
rapidly. Wait until the LED blinks slowly again before proceeding.
Moving the Beam to Calibrate
When pressing an arrow key to move the beam up or down to reach
proper calibration, use short, rapid clicks. Do not hold the key down.
After pressing the key, the LED will blink rapidly as the laser reacts. Wait
until the LED returns to a slow blink to proceed.
If the +X or +Y axis is toward the wall with the marks, use the
∧ key to raise
beam, and the
∨ key to lower beam. If the –X or -Y axis is toward the wall,
it’s the opposite: use the
∨ key to raise the beam and the ∧ key to lower the
beam.

How To Use The LT200
Setup
Horizontal
The laser can be used on a 5/8-11 tripod, on a wall mount, or directly on a
solid, stable surface.
The LT200 has a wide self-leveling range; however, if the laser is set up out
of the leveling range, laser beam will continue to blink and rotation will not
start.
Turning On the Laser
Turn on the laser with the On / Off key (3). It does a self-test and the beam
blinks while the laser is self-leveling. After it’s levelled, the head rotates.
H.I. Alert
H.I. (height of instrument) Alert stops the laser automatically if the laser is
disturbed or moved, preventing inaccurate readings.
It will function only when selected. To activate this safeguard feature, press
the H.I. Alert key (1). The LED indicator (3) will blink rapidly while the
laser is self-leveling
About 30 seconds after the head starts to rotate, the LED will blink slowly,
indicating the H.I. Alert is activated.
If the laser is disturbed while in H.I. Alert mode, the head will stop rotating, the
beam will turn off, and the LED will stay on.
To start the laser rotating again, press On/Off twice.
Check to see if the beam elevation has changed from its original benchmark
position.
The laser is no longer in H.I. Alert mode. Press key (1) to return to H.I. Alert.
