3.1 Handling Instructions
The
personal
DataRAM is a sophisticated optical/electronic instrument and should be
handled accordingly. Although the
personal
DataRAM is very rugged, it should not
be subjected to excessive shock, vibration, temperature or humidity. As a practical
guideline, the
personal
DataRAM should be handled with the same care as a portable
CD player.
If the
personal
DataRAM has been exposed to low temperatures (e.g. in the trunk of a
car during winter) for more than a few minutes, care should be taken to allow the
instrument to return near room temperature before operating it indoors. This is
advisable because water vapor may condense on the interior surfaces of the
personal
DataRAM causing temporary malfunction or erroneous readings. Once the
instrument warms up to near room temperature, such condensation will have
evaporated. If the
personal
DataRAM becomes wet (e.g. due to exposure to water
sprays, rain, etc.), allow the unit to dry thoroughly before operating.
Whenever the
personal
DataRAM is shipped care should be taken in placing it in its
carrying case and repackaging it with the original cardboard box with the factory
provided padding.
3.2 Safety Instructions

Shut off
personal
DataRAM and any external devices (e.g. PC or Laptop) before
connecting or disconnecting them.

personal
DataRAM before replacing the internal battery, or when

Handling and Operation
3.3.1 Model pDR-1000AN
The model
p
DR-1000AN can be operated in any position or orientation. Exposure to
high intensity fluctuating light of the interior of the sensing chamber, through the
front and back slotted air openings (see Section 5.5), should be avoided. Such large
intensity transients may cause erroneous readings. Direct access of sunlight to the
sensing chamber should be prevented.
