INSTRUCTION MANUAL
LASER SENSOR
LS-B200
Thank you for purchasing the TOPCON LS-B200.
For the best performance of the instruments, please read these instructions
carefully and keep them in a convenient location for future reference.
GENERAL HANDLING PRECAUTIONS
Before starting work or operation, be sure to check that the system is functioning
properly.
• Remove the batteries from the instrument when you will not be using it for
long period.
• Replace all 4 dry batteries with new ones at the same time. Do not mix used
and new dry batteries, and do not mix different types of dry batteries together.
• Use alkaline dry batteries. Nickel hydrogen dry batteries and nickel cadmium
dry batteries can be used too, but the operating time is different from the time
of alkaline dry batteries.
• Do not submerge the instrument in water.
• This instrument is designed based on the International Standard IPX 6, but it
is not protected from a high pressure water stream or submergence.
• When washing the instrument, avoid spraying it with a high pressure stream
of water from a water hose. The inside of the instrument will be damaged by
the water.
• Be sure to charge the battery within the charging temperature range.
Charging temperature range: 10 to 40°C
• Battery is an expendable item. The decline in retained capacity depending on
the repeated charging/discharging cycle is out of warranty.
• Affection of the radio waves
When using the instrument in the following place, the strong radio wave may
cause faulty operation.
• Near the instrument occurring strong radio waves. (e.g. Transceiver)
• Near the radio wave towers such as television or radio.
• When transporting the instrument, provide some protection to minimize risk of
shock. Heavy shock may affect beam accuracy.
• In addition to the laser beam emitted from the rotating laser, the laser sensor
may be sensitive to smartphone screens, LED lamps, fluorescent lamps, con-
striction lamps, and other modulated lights. In this case, turn off these modu-
lated lights that may be the cause, or block them before performing
measurement.
• If an object (glass window, car windshield, etc.) that may reflect a laser beam
is close to this instrument, the laser sensor may malfunction. When using this
instrument, block the laser beam to the direction of a reflective object.
Examples of malfunctions:
• The display shows ""even though the location is not a datum posi-
tion.
• Errors occur for the datum position.
• The display does not show ""even though the location
is a datum position.
• Be sure that the laser emitting window of this instrument, and
the beam receiving window of the laser sensor are free from dirt
(oil, water droplets, etc.). The measurement result may be in
error if these windows are dirty.
PRECAUTIONS FOR SAFE OPERATION
For the safe use of the product and prevention of injury to operators and other
persons as well as prevention of property damage, items which should be
observed are indicated by an exclamation point within a triangle used with

PARTS OF THE INSTRUMENT AND FUNCTIONS
REPLACING THE BATTERY
Dry battery
1Remove the DB-83 battery holder by turning the battery cover knob.
2Remove the old batteries and replace with new ones.

2Attach the charged BT-83Q to the LS-B200.
3Attach the battery cover by turning the battery cover knob.

• Batteries generate power using a chemical reaction and as a result have a limited life-
time. Even when in storage and not used for long periods, battery capacity deteriorates
with the passage of time. This may result in the operating time of the battery shortening
despite having been charged correctly. In this event, a new battery is required.
OPERATION
1Position a rotating laser and turn on the laser.
2Raise or lower the machine blade or arm to position the cutting
edge or bucket at the desired grade elevation.
3Mount the LS-B200 onto the mast near the path of the laser beam
and turn on the LS-B200.
4Keep the machine blade or arm motionless and raise or lower the
LS-B200 and adjust until ON-GRADE position are blinking. This is
the ON GRADE position.
5Securely clamp the LS-B200 in place. The reference position has been set.
6While operating, use the LED display to continually check grade, moving the
blade or cutting / filling according to the direction of the LS-B200 display.
WARNING Ignoring this indication and making an operation error could possibly
result in death or serious injury to the operator.

This instrument will enter the power-save mode when no switches are
operated or no laser beam is received for about five minutes. During
the power-save mode, two LEDs (one yellow and one red) will blink.
(When the laser beam is received again, the power-save mode will be
automatically turned off. Or when the power switch is pressed again,
the power-save mode will be also turned off.)
To disable the power-save function, press the power switch for at least
five seconds to turn the power on. When the function is disabled, the
LED shown in the figure will blink twice.

CHANGING THE ON-GRADE POSITION FUNCTION
The ON-GRADE position can be changed to the position where laser beam is detected.
Using this function when installing the LS-B200 on the pole of the machine allows easy
setting of the height at which the ON-GRADE will be displayed on the LS-B200. The
range in which the ON-GRADE position can be changed is ±50mm (total of 100mm)
from the center of the detective range.
In order to set the ON-GRADE position at high precision, set it while the laser beam is
stable. When setting the ON-GRADE position while the laser beam is unstable (when
using at a long-distance - more than 150m - or when atmospheric condition is unstable
due to air shimmering or other conditions), the sensor will automatically detect it and the
LED indicating the failure will be displayed while changing the ON-GRADE position.

1Long-press the zero-set switch while detecting the
laser beam.
When changing the ON-GRADE position, the LED
lights up for three seconds, as shown in the figure.
The position where the laser beam is being detected
will be the ON-GRADE position.
The LED blinks as shown in the figure for three sec-
onds when you have failed to change the ON-
GRADE position. Be careful not to change the posi-
tion at which the laser beam is detected and try set-
ting once again.

1Long-press the zero-set switch when not detecting
the laser beam. The ON-GRADE position will be
reset.
When the ON-GRADE position change is cancelled,
the LED (3 green) blinks for three seconds.

LED brightness adjustment function
(Effective only when using the internal battery)
This instrument detects the ambient brightness and automatically adjusts the LED
brightness (high/low). If you want to keep the LED brightness high, turn the power
switch on while holding down the detective precision (Mode) switch.

CONNECTOR FOR EXTERNAL POWER SUPPLY
Connecting the connector cable PC-18 (sold separately) to the connector for exter-
nal power supply will enable the use of the LS-B200 from an external power supply.
The LS-B200 will turn on when connection is made to external power supply. The
power switch of the instrument will not function when an external power supply is
used.
When the instrument is operated with the external power supply, the power-save
and the auto-cut off functions will be invalidated.
