[Usage precautions]

Surveying instruments are high-precision instruments. In order to assure that the Electronic
Total Station W-800X 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 specially designed solar filter (MU64) to
the objective lens.

[Laser beam]

Do not stare into laser beam.W-800 series is a class-II Laser product.
(The reflectorless type is a Class IIIa (3R) laser product.)

[EDM axis]

The W-800 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 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:
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.

• Note the following possibilities when performing reflectorless measurement. In a
situation high accuracy cannot not be expected, perform the measurement by reflector
sheet or prism (W-822NX, W-823NX,W-825NX,W-835NX)

• 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.

7

• 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 perpendicular
to the aiming line. If it is positioned not to be perpendicular, there is a possibility that
correct distance measurement may not be performed by dispersion or reduction of
laser beam. In the following environments, the distance might not be able to be
measured. There is is a reflecting object (mirror, stainless board and white wall, etc.) in
the direction of the target and under too strong sun light.

[Battery & charger]

• Do not use any batteries and battery chargers other than those PENTAX assured ade­quate as it 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 out 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.

[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 Focus ring.

[LD POINT, laser pointer]

When making 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 SD card, CF card and 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 SD
card, CF card or USB Connector.

[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.

[Data saving]

When using application software, store data in SD card drive, CF card drive or DiskOnChip folder.
Data stored in other drives is deleted when the power is turned OFF.

[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 environment, allow the instrument to adjust to the environment for an hour
or more before using it. 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.
