How to Use the Model LL200
CAUTION: Be sure to handle the
laser by the body rather than the top
(sunshade). The sunshade protects
the glass window that the beam
comes out of. The window can break
if handled improperly.
Receiver
1. Open the battery door using
a coin or your thumbnail.
2. Install/Remove the 2 AA
batteries noting the positive
(+) and negative (–) diagram
inside the housing.
3. Push down on the battery
door until it “clicks” into
position.
Setting Up and Leveling the Laser
1. Set up the laser in the middle of your work area (or wherever is best
for your application needs). Make sure the setup is stable.
Note: The maximum operating
diameter is 130 m (430 ft) in the
Y axis and 300 m (1000 ft) in
the X axis. The minimum operating
distance to a wall is 6 m (20 ft).
Note: For best system performance, do not set up the laser within
6 m (20 ft) of a wall. Also do not use the receiver within 6 m (20 ft)
of the laser or within 1.5 m (5 ft) of a wall. At these close ranges, the
receiver’s electronics may give incorrect beam elevation information
due to the laser beam reflecting off of the walls.
2. Press the power button to turn on the laser. All LEDs flash once to
show that they are working.
3. Level the laser using the bull’s eye as a reference.
CAUTION: When leveling the LL200, be sure not to rotate the laser
more than 360°. Doing so can cause the extension spring that holds
the laser to the leveling base to break. If rotating the laser becomes
difficult, turn the laser 180° in the opposite direction.
Note: When the laser is level, the bubble is centered in the bull’s-eye
and the green level LED lights. The LED stays lit for the first five
minutes the laser is level then flashes once every five seconds.

Turning On/Off the Receiver
1. Press the power/audio
button to turn on the
receiver.
Note: When the receiver
is initially turned on/off,
all LCD symbols, LEDs,
and the audio signal are
turned on for one second
(diagnostic mode). After the
diagnostic mode is complete,
the grade sensitivity (fine) and the audio (loud) symbols appear.
2. Press and hold the power/audio button for one second to turn off
the receiver.
Turning On/Off LEDs
The LEDs show the position of the receiver relative to the laser beam.
Turning off the LEDs extends battery life.
The factory default setting for the LEDs is on.
1. Press the grade-sensitivity and power/audio buttons repeatedly to
turn the LEDs on or off.
Note: When the LEDs are turned on, all LEDs light for one second;
when the LEDs are turned off, both red LEDs light for one second.
Selecting the Grade Sensitivity
The receiver always starts up with the on-grade sensitivity (fine) active.
1. Press the grade-sensitivity button repeatedly to select between fine:
1.5 mm (1/16 in.) and medium: 3 mm (1/8 in.) grade sensitivity.
Selecting the Audio Function
The receiver always starts up with the audio mode (loud) active.
1. Press the power/audio button repeatedly to cycle through the audio
levels, which include off, soft, and loud.
Note: If the audio function is on, the receiver beeps quickly when
the receiver is above the laser beam, slowly when below it, and
continuously when centered in the laser beam or on grade.
Using the Receiver with a Laser
1. Press the power/audio button to turn on the receiver.
2. Position the receiver so that its photocell faces the laser.
3. Move the receiver up/down until the LCD and LEDs show an
on-grade reading.
Note: The LCD shows a down arrow when the receiver is above the
laser beam, an up arrow when below it, and a horizontal line when
centered in the laser beam.
Note: The top/bottom LED flashes when the receiver is within
6 mm (1/4 in.) of being on grade and light continuously when the
receiver is between 6 mm and 25 mm (1/4 in. and 1 in.) of being
above or below the laser beam. The green LED flashes when the
receiver is on grade.

Determining the Height of Instrument (HI)
The height of instrument (HI) is the elevation of the laser’s beam.
The HI is determined by adding the grade-rod reading to a benchmark
or known elevation.
1. Set up and level the laser.
2. Attach the receiver to a grade rod and turn on the receiver.
3. Place the grade rod on a job-site benchmark (BM) or known
elevation.
4. Slide the receiver up/down the grade rod until the LCD shows an
on-grade reading.
5. Add the grade-rod reading to the benchmark to determine the
height of instrument.
Example: Benchmark elevation = 30.55 m (100.23 ft)
On-grade rod reading = + 1.32 m (4.34 ft)
Height of instrument = 31.87 m (104.57 ft)
6. Use this HI as a reference for all other elevations.
Checking Calibration
As with any precision instrument, the calibration needs checking on a
regular basis (such as at the beginning of a job, or if the laser has been
handled roughly). If the laser is being used at temperatures below
freezing, be sure to check calibration under those conditions. The laser
is calibrated if the laser plane is within ±2.2 mm (±3/32 in.) of true
level at 30 m (100 ft). If the laser has a calibration error, go to the
“Request for Service” section of this manual to get more information.
CAUTION: When checking all four axes for a calibration error, be
sure not to rotate the laser more than 360°. Doing so can cause the
extension spring that holds the laser to the leveling base to break. If
rotating the laser becomes difficult, turn the laser 180°in the opposite
direction.
1. Set up and level the laser 30 m (100 ft) from a wall.
2. Use the receiver to take an elevation reading for the +Y axis.
3. Rotate the laser 180° (–Y axis toward the wall) and re-level the laser.
4. Use the receiver to take an elevation reading for the –Y axis.
5. Calculate the difference between the two elevation readings. If they
differ more than 4.4 mm (3/16 in.), the laser needs calibrating.
Return the laser to an authorized Trimble service center for servicing.
6. To check the X axis, repeat steps 1–5 using the X axis instead of the
Y axis.
