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 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.
