To clean the filters with a jet of dry air, choose Film
mode, Tricolor mode and set the exposure time to 4 sec.
Make some exposures.
Take special care to store the sinarcam in a dust-free
environment, and never leave it for a long time with one
of the filters in the visible position.
Gently wipe the filter. For wiping you should use a non-
scratching, clean, dry and lint-free cleaning tissue or a
cleaning cloth for eyeglasses. Special precautions should
be taken for the tissue or cloth to have no grease (from
sweaty palms, hand creams, etc.), which could
inadvertently be transferred to the surfaces of the filters.
The wiping should be performed in only one direction,
and only with very gentle pressure. It should furthermore
be restricted just to the tarnished area.
Please note that the humidity in one' s breath can cause
dust particles to adhere to the surfaces of the filters.
To clean the filters with a cleaning cloth, turn off the
power supply and manually turn the filter wheel. Avoid
any contact with the filters itself and try to touch only the
wheel.
WARNING: Frequent cleaning by wiping can lead to
reduced filter effectiveness (surface dulling)
