[Usage precautions]
Surveying instruments are high-precision instruments. In order to assure that
the Electronic Total Station LGP-300N series product which you have purchased
will provide long-lasting maximum performance, the precautions in this manual
must be followed. Be 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 special solar filter designed for this product to the objective lens.
[Laser beam]
Do not stare into laser beam. LGP-300N series is a Class IIIa (3R) laser product.
[EDM axis]
The LGP-300N series EDM is the red visible laser beam and the beam diameter is
very small. The beam is emitted from the objective center and the base plate
center hole. The EDM axis is designed to coincide with the telescope sight axis
but both axes may not sometimes coincide slightly according to the intense
temperature change and 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.

11
[Reflectorless and reflector sheet]
● Reflectorless:
The measurement range and accuracy of Reflectorless are based on the
condition that laser beam is emitted perpendicular to the white side of the
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.
● Pay attention to following in case of distance measurement by Reflectorless.
In a situation resulting in low accuracy, perform the distance measurement by
Reflector sheet or Prism.
● There is a possibility that correct distance measurement may be impossible by
dispersion or reduction of laser beam when the laser beam comes into the
target from diagonal angle.
● There is a possibility that the instrument cannot calculate correctly when
receiving reflected
laser beam from forth and back directions in case of measuring the target on
the road.
● There is a possibility that synthesized values are calculated and the distance
may become longer or shorter than the actual one when the operator measure
the target of slope or sphere or rugged shape.
● There is a possibility that the instrument cannot calculate correctly by
collecting the reflected laser beam from a man or a car that comes and goes in
front of the target.
● When using Reflector sheet, set the Reflector sheet to have its surface be approx.
vertical to the aiming line. If it is positioned not to be approx. right angle, there
is a possibility that correct distance measurement may be impossible by
dispersion or reduction of laser beam.
In the following environments, the distance might not be able to be measured.
There is a reflection things (mirror, stainless board and white wall etc.) in the
direction of the target and under too strong sun light.

12
[Battery & charger]
● Never use any battery charger other than the BC05 battery charger as this may
result in damage to 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 estimate of remaining
battery power and is not completely accurate. Replace the battery quickly when
it is about to run down as the time a battery lasts on one charge differs
depending on conditions of ambient temperature, and the measurement mode
of the instrument.
● Confirm the battery level remaining before operating.
●When the remaining battery power becomes low, a message to alert battery
run-out starts coming up. When the message appears, replace the battery to a
fully charged one immediately. Running out of battery in middle of use may
result in loss of data.
[LD POINT, laser pointer]
When you make a correct direction using the “LD POINT”, aim the laser beam at
the wall and mark the center and then confirm the discrepancy between the
reticle center and the marked point beforehand.
[Interface]
Do not insert or remove USB Connector outdoors.
Be careful not to let dust, mud, sand, water, harmful gas or salty steam enter the
card slot or USB connector port.
Be sure to turn the instrument’s power off before inserting or removing the USB
Connector.

13
[Touch panel]
Use the Stylus pen when you touch the panel for operation of software.
Do not touch the panel with any things such as fingertips or pen point as this may
scratch and damage the screen.

14
[Storage and operating environment]
● To prevent making short-circuit when removing the battery and charger from
the case and storing them, apply electrically resistant tape to the poles of the
battery. Storing the battery and charger as is 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 is present. 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 locations allow the instrument to adjust to the ambient for
an hour or more before use. Be sure to protect the instrument from the sun if
the location is subject to intense direct sunlight.
● During surveys for which the survey precision or atmospheric measurement
method has been defined measure the atmospheric temperature and pressure
separately and enter those values rather than using the Automatic
Atmospheric Correction function.
● 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 materials around it and be sure it is handled as “FRAGILE”.

15
[Checks and repairs]
● Always check the instrument before beginning work and check that the
instrument is maintaining the proper level of precision. TI Asahi 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.
● Never disassemble the instrument, battery or charger even if you do detect an
abnormality as there is a rink of fine 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.
