PRECAUTIONS REGARDING SAFETY

Usage precautions

Surveying instruments are high-precision instruments. In order to assure that the Electronic Total Station R-300X 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-300X is a class-II Laser product. (The reflectorless type is a Class IIIa (3R) laser product.)

[EDM axis]

The R-300X 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.

[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. (R-315NX, R-325NX, R-335NX, R-322NX,R-323NX)

• 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.

PRECAUTIONS REGARDING SAFETY

• 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.

[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.

PRECAUTIONS REGARDING SAFETY

[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 shockabsorbing 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.
