Pulsar QUANTUM LQ19 Manual Del Usuario página 10

The scope can be used in operating temperatures ranging from -25 °C
to +50 °C. However, if it has been brought indoors from cold
temperatures, do not turn it on for at least 2-3 hours. This will prevent
external optical surfaces from fogging.
Always store the unit in its carrying case in a dry, well-ventilated space.
Remove the batteries if the scope is not going to be used for an
extended period (longer than one month).
Batteries shall not be exposed to excessive heat such as sunshine, fire
or the like.

TROUBLESHOOTING
Listed below are some potential problems that may occur when using the
scope. Carry out the recommended checks and troubleshooting steps in
the order listed. Please note that the table does not list all of the possible
problems. If the problem experienced with the scope is not listed, or if the
suggested action meant to correct it does not resolve the problem, please
contact the manufacturer.

The spot effect is due to the constructive peculiarity of the
objective lens and is most noticeable in extreme non-
operating lens focus positions when observing objects with
uniform low temperature contrast, i.e. clear sky. This is not a
defect.

contrast and, thus, quality of the image produced by a thermal
imager, will be better.
At low operating temperatures objects under observation
(background) normally cool down to roughly equal
temperatures which leads to lower temperature contrast, and
to image quality (precision) degradation. This is normal for
thermal imaging devices.
