PRECAUTIONS REGARDING SAFETY

CAUTION

For security, please do the opening inspection and inspection every a fixed period and adjustment.

When the laser beam enters eyes, an unexpected accident might be caused by the blink of eyes. Establish the laser product to avoid the height of eyes of a driving person and walker. Establish an instrument so that laser beam does not hit a reflection thing as a mirror and a glass window. The refection beam of the laser is also harmful to the human body.

Besides the time when you measure the distance, cut off the power supply or shade the beam of aperture with caps.

Keep the laser product in the place where the person who does not have the product knowledge such as children does not touch by mistake.

Destroy the power supply mechanism of the instrument so as not to emit the laser beam when throwing away it.

Do not remove the handgrip without good reason. If it does come off, be sure to attach it securely to the instrument with screws. If it is not fastened securely, the instrument may fall when you grasp the handgrip, leading to possible injury.

Do not short the poles of the battery or charger as there is a risk of injury or fire.

Do not touch any fluid which may leak from the battery as there is a risk of chemical burn injury or reaction.

Do not insert or remove the electric plug with wet hands as there is a risk of electric shock.

Do not use the case to stand on as it is slippery and unstable and may cause you to fall, resulting in possible injury.

Be sure the tripod itself and the instrument on the tripod are both installed securely as insecure installation may cause the tripod to fall over or the instrument to drop, resulting in possible injury.

Do not carry the tripod with the metal shoe pointing toward another person as the person may be injured if they strike him or her.

Ni-MH

PRECAUTIONS REGARDING SAFETY

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 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]

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 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-315N/R-325N/R-335N/R-322N/R-323N)

qThere 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.

w 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.

3

PENTAX R-300 (p01-19) 10/30/02 11:20 AM Page 4

PRECAUTIONS REGARDING SAFETY

eThere 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.

rThere 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.

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.

e When the charge is completed, the charge lamp is turned off.

r Detach the battery packing from the charger when the charge is completed.

Refreshing the battery

The use time shortens gradually by the phenomenon of “Effect of the memory” when the NiMH battery leaves capacity and repeats the charge. The voltage recovers after refreshing and the use time returns normally in such a battery. Please refresh one degree every five times of the charge.

[Refreshing]

Set the battery in the charger as well as the case of the charge. Push the electrical discharge button. The electrical discharge lamp lights and the electrical discharge begins.

The electrical discharge lamp is turned off when the electrical discharge ends, the charge lamp lights, and the charge starts automatically. Leave just as it is until the charge is completed. When the charge is completed, the charge lamp is turned off. Detach the battery from the charger.

[Time of refreshing and charge]

Battery BP02 is discharged from the state of a full charge at about 960 minutes and the charge is completed from the electrical discharge at about 130 minutes. However, the electrical discharge time is proportional to the remainder capacity of the battery. Moreover, the time required for refreshing might be different from the above-mentioned time according to a surrounding temperature and the state of the battery.

3 PREPARATION FOR SURVEYING

The brightness adjustment step of the laser is 10 steps.

The laser plummet spot can become difficult to see in bright sunlight which makes it difficult to perform the occasional check. In this case, use your foot or the carrying case to make a shadow over the laser position.

The laser plummet is adjusted to be within ±0.8 mm at the instrument height of 1.5m at factory shipping.

Please confirm the amount of the gap (direction of X and Y direction) with the laser plummet beforehand compared with plumb bomb etc. when working like accurately putting out a perpendicular direction using the laser plummet function.

Please do not look at the laser source of beam directly.

3-3 Optical plummet (Option)

[Detachable type]

qLook through the optical plummet eyepiece, and rotate the eyepiece knob until the center mark can be seen clearly.

wRotate the focusing knob of the optical plummet and adjust the focus to the station on the ground.

e Rotate the levelling screws and aligh the center mark to the ground mark.

[Shift type]

qLook through the optical plummet eyepiece, and rotate the eyepiece knob until the center mark can be seen clearly.

wRotate the focusing knob of the optical plummet and adjust the focus on the ground mark.

eLoosen the centering clamp screw and push the upper plate by finger and stay the center mark on the ground mark.

r Tighten the centering clamp screw.

tLoosen the horizontal clamp screw and rotate the instrument every 90° and confirm the Circular vial is centered correctly. If the bubble is not centered, it can be properly set using the leveling screws.
