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

PARTS OF THE INSTRUMENT AND FUNCTIONS
REPLACING THE BATTERY
Dry battery
1 Remove the DB-83 battery holder by turning the battery cover knob.
2 Remove the old batteries and replace with new ones.
Rechargeable battery
1 Remove the BT-83Q by turning the battery cover knob.
2 Attach the charged BT-83Q to the LS-B200.
3 Attach 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
1
Position a rotating laser and turn on the laser.
2 Raise or lower the machine blade or arm to position the cutting
edge or bucket at the desired grade elevation.
3 Mount the LS-B200 onto the mast near the path of the laser beam
and turn on the LS-B200.
4 Keep 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.
5 Securely clamp the LS-B200 in place. The reference position has been set.
6 While operating, use the LED display to continually check grade, moving the
blade or cutting / filling according to the direction of the LS-B200 display.
