Usage precautions
Surveying instruments are high-precision instruments. In order to assure that the LTS-200
series total station which you have purchased will provide long-lasting maximum
performance, the precautions in this manual must be followed. Make sure to follow these
instructions and use this product properly at all times.
[Solar observation]
WARNING
Never view the sun directly using the telescope as this may result in loss of sight.
Never point the objective lens directly at the sun as this may damage internal components.
When using the instrument for solar observation, be sure to attach the specially designed solar
filter (MU64) to the objective lens.
[Laser beam]
Do not stare into the laser beam. LTS-200 is a Class IIIa (3R) Laser product.
[EDM axis]
The EDM of the LTS-200 series uses a red visible laser beam and its beam diameter is very
small. The beam is emitted from the objective centre. The EDM axis is designed to coincide
with the telescope sight axis (but both axes may deviate slightly because of intense
temperature changes and a long time lapse).
[Target constant]
Confirm the Target Constant of the instrument before measurement.
If a different constant is to be used, use the correct constant of the target. The constant is
stored in the instrument's memory when turned off.
[Reflectorless and reflector sheet]
•Reflectorless (Non-Prism)
The measurement range and accuracy of the Reflectorless mode are based on the condition
that laser beam is emitted perpendicular to the white side of a Kodak Gray Card.
The measurement range may be influenced by the shape of the target and its environment.
There is a possibility that the range may vary when the target does not satisfy the
conditions above at survey work.
•There is a possibility that correct distance measurement may not be performed by
dispersion or reduction of laser beam when the laser beam comes into the target from a
diagonal angle.
•There is a possibility that the instrument may not be able to correctly calculate out the
distance when receiving reflected laser beam from forth and back directions in case of
measuring the target on the road.

8
•There is a possibility that synthesized values are calculated and the distance may become
longer or shorter than the actual one when the operator measures the target of slope or
sphere or rugged shape.
•There is a possibility that the instrument may not be able to correctly calculate out the
distance by collecting the reflected laser beam from a man or a car that comes and goes in
front of the target.
•There is a possibility that the distance may not be correctly measured when measuring a
target in the direction where there is a reflecting object (mirror, stainless board, white wall,
etc.) or under too strong sunlight.
•In a situation where high accuracy may not be expected, perform the measurement by
Reflector sheet or Prism.
•When using reflector sheet, set the reflector sheet to have its surface to be approx. vertical
to the aiming line. If it is positioned not to be approx. right angle, there is a possibility that
correct distance measurements may be impossible by dispersion or reduction of laser beam.
In the following environments, the distance may not be possible to be measured; there is a
reflecting thing (mirror, stainless board, white wall, etc.) in the direction of the target, and
under too strong sunlight
[Battery & charger]
•Do not use any battery or battery charger that is not approved by LINERTEC as it entails a
risk of damaging the instrument.
•If water should happen to splash on the instrument or the battery, wipe it off immediately
and allow it to dry in a dry location. Do not put the instrument in the case until it is
completely dry as this may result in damage to the instrument.
•Turn off the power when removing the battery from the instrument as removing the battery
while the power is still on may result in damage to the instrument.
•The battery mark displayed on the instrument is only an estimation of remaining battery
power and is not completely accurate. Replace the battery quickly when it is about to run
out of power as the time a battery lasts on one full charge differs depending on conditions
of ambient temperature, and the measurement mode of the instrument.
•Confirm the battery level remaining before operating.
[About Clock Battery (lithium)]
•Clock battery is a backup battery used for calendar clock function.
•The battery can last about five years with regular use, but it is possible to be shorter
depending on usage.
•When the voltage of the clock battery is low or runs out, the date and time display
incorrectly and indication of "Clock-batt. voltage low" will appear.
•Please contact your the dealer which the purchased was mail for any exchange or return of
the clock battery.
[LD POINT, laser pointer]
When you make a correct direction using the “LD POINT”, aim the laser beam at the wall and
mark the centre and then confirm the discrepancy between the reticle centre and the marked
point beforehand.
[Storage and operating environment]

9
•To prevent making short-circuit when removing the battery and charger from the case and
storing them, apply electric resistant tape to the poles of the battery. Storing the battery and
charger as it may result in fire or burn injury due to short-circuit.
•Avoid storing the instrument in places subject to extreme high, low or radically fluctuating
temperature. (Ambient temperature range during use: –20° C to +50° C)
•Distance measurements may take longer when atmospheric conditions are poor such as
when heat shimmer occurs. When storing the instrument, always put it in its case and avoid
storage in dusty location or location subject to vibration or extreme heat or humidity.
•Whenever there is a sharp temperature difference between the instrument’s storage and
usage environment, allow the instrument to adjust to the environment for an hour or more
before using it. Make sure to protect the instrument from the sun if the location is subject to
intense direct sunlight.
•The battery should be charged approximately once per month if the instrument is to be
stored for an extended period of time. The instrument should also be removed from its case
occasionally and aired out.
•In addition to these precautions, be sure to handle the instrument properly at all times
following the descriptions given in the various sections of this manual to assure safe and
proper measurements.
[Transporting and carrying the instrument]
•Be careful to protect this instrument from shock of impact and excessive vibration which
may result in damage during transportation and shipment.
•When transporting the instrument, always put it in the case and wrap shock absorbing
material around it and be sure it is handled as “FRAGILE”.
[Checks and repairs]
•Always check the instrument before beginning work and check that the instrument is
maintaining the proper level of precision. LINERTEC bears absolutely no responsibility
for damages due to survey results obtained from surveys conducted without an initial
instrument check.
•Never disassemble the instrument, battery or charger, even if you do detect an abnormality,
as there is a risk of fire or electric shock due to short-circuit. If you think the product
requires repair, contact the retail outlet where you purchased it or an authorized repair site.
