Section IV. OPERATION UNDER UNUSUAL
at Low Temperatures
Equipment to be operated at low temperatures
should be stored at approximately the same tem-
perature as that in which it will be used. The
camera set can be operated normally at low tem-
peratures if the procedures given in a and b below
a. Storing Equipment at Low Temperatures.
Avoid rapid changes in temperature. Such changes
affect the film. If the equipment is stored in a
colder location than where it will be used, follow
the procedures given in (1) , (2) , and (3) below.
(1) Transfer t h e e q u i p m e n t f r o m t h e l o w -
temperature storage location to the warmer location at
least 6 hours in advance of its anticipated use.
(2) Remove any moisture on the outer plastic
and metal surfaces of the equipment with a soft, lint-
free cloth before operating the equipment.
(3) Clear the surfaces with a lens tissue dam-
pened with lens cleaner if any moisture is present on
the exposed optical surfaces.
(4) Dry the exposed optical surface with a clean
If moisture has condensed on the inner surfaces of
the optical components, allow the equipment to
remain long enough for the moisture to evaporate.
