Touch Panel - Pentax W-821NX Basic Instruction Manual

[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 but-
ton 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 sto-
red 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.
