Usage Precautions
Surveying instruments are high-precision instruments. In order to assure that the
Electronic Total Station R-300 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 (MU64) designed for this product to the
objective lens.
[Laser Beam]
Do not stare into laser beam. R-300 is a class-II Laser product. The reflectorless
type is a Class IIIa (3R) laser product.
[EDM axis]
The R series EDM is the red visible laser beam and the beam diameter is very small.
The beam is emitted from the objective center. 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.
[Reflectorless and Reflector sheet]
ꢀ The measurement range is determined by the white side of the Kodak Gray
Card facing the instrument and by its surrounding brightness.
There is a possibility that the range may vary when the target does not satisfy
the conditions above at survey work.
ꢀ Pay attention to followings in case of distance measurement by Reflectorless.
In case of resulting in low accuracy, perform the distance measurement by
Reflector sheet or Prism. (R-315N/R-325N/R-335N/R-322N/R-323N)
① 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.
② 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.
Download from Www.Somanuals.com. All Manuals Search And Download.
P3
PRECAUTIONS REGARDING SAFETY･
③ 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.
④ 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.
[Battery & Charger]
Never use any battery charger other than the BC03 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.
[Auto focus]
The Auto focus mechanism is very precise but will not function under every
condition. Focusing depends on brightness, contrast, the shape and size of the
target.
In such a case, press the AF button and focus on the target by operating the
Power focus key or the AF ring.
[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.
[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.
P4
PRECAUTIONS REGARDING SAFETY
ꢀ 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
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. Pentax 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.

The instrument is horizontally rotated by 180 degrees after the vial of an Electronic vial is adjusted on the
center at a Left circle position side and confirm that the vial of the vial is at the center at the right circle
position.
[When using the Automatic inclination correction by 0 axis ]
⑥ Confirm the vial is at the center even if the instrument is rotated by each 90°.Confirm whether the
instrument is on the ground mark. When you can confirm it is just on the mark loosen the center
screw and move the instrument on the ground mark correctly and fix the instrument by a center
screw. Repeat from ① to ⑥.
3-6 Eyepiece Adjustment
Eyepiece adjustment
The eyepiece adjustment is performed before
target sighting.
① Remove the telescope lens cap.
② Point the telescope at a bright object, and rotate
the eyepiece ring full counter-clockwise.
③ Look through the eyepiece, and rotate the
eyepiece ring clockwise until the reticle appears
as its maximum sharpness.
ꢀ When looking into the eyepiece, avoid an intense look to prevent parallax and
eye fatigue.
●When it is hard to see the reticle due to poor brightness, press Illumination key to
illuminate it . For adjusting intensity of brightness, refer to page X.

3 PREPARATION FOR SURVEYING･
[Target sighting by Auto focus]
The Auto focus of R-300 series has following two modes.
1. Normal mode : Pressing AF button focuses on the target.
2. Continuous mode : Pressing AF buttons for two seconds beeps, and releasing
the key enters into the Continuous mode. This mode
enables you to perform the Auto focus approx. for one
minutes only by sighting the telescope and chasing the
target.

q Loosen the telescope clamp and horizontal clamp screws.
w Point the telescope at the target using a collimator.
e Tighten the above two screws.
r Adjust the eyepiece.
t Look through the telescope and press the AF button. Move your eye vertically
and horizontally to see if the target image moves in relation to reticle.
y Stay the reticle accurately on the target using telescope and horizontal
tangent screws.
If the target image does not move, there is no parallax. If it moves, eliminate
the parallax.
Even when vertical angle measurement is not performed, it is recommended
that the target should be placed at the reticle center.
Operating the Power focus key rotates the AF ring, so do not touch it while it
