7. Camera Care
The camera should be handled carefully. Keep it clean, protect from sharp jolts, moisture and sharp
temperature fluctuations.
Do not keep the camera for a long period of time with the shutter cocked. Thus you will save the
spring. Wind the shutter always to the stop.
Keep the camera in a closed carrying case. The grip should be removed and fastened to the case
cover.
Before rewinding the film, remove the viewfinder and put it into the carrying case.
Do not touch the optical surfaces with hands as this may cause deterioration of the coating.
The coated optical surfaces should be cleaned only with a clean soft cloth or cotton wool, slightly
moistened in alcohol.
Since the camera is a complicated optical mechanical device, it should be repaired and adjusted
only by highly trained specialists and in repair shops.
