• There is a possibility that the distance may not be correctly measured when measuring a
target in the direction where there is a reflecting object (mirror,stainless board and white
wall, etc.) or under too strong sun light.
• In a situation high accuracy may not be expected, perform the measurement by prism.
[Battery & charger]
• Do not use any battery or battery charger that is not approved by Pentax as it entails a risk
of damaging 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 estimation of remaining battery
power and is not completely accurate.Replace the battery quickly when it is about to run
out of power 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.
[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 it 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 occurs.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 follo
wing 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.
