Do not remove the camera from its case the moment it is brought indoors from cold to avoid
sweating of its parts, especially the optical ones.
Do not touch the surfaces of the optical parts with fingers since it may damage their coatings. Clean
the optical coated lens surfaces with a clean soft cloth or cotton wool wad slightly moistened with
rectified alcohol or ether. The surfaces of the mirror and the focusing device may be cleaned only if
absolutely necessary with a dry soft brush but in no case with humid cleaning agents.
Keep the camera closed in its case with the cap put on the lens.
Do not remove the lens from the camera without need to prevent dirt and dust from getting both
onto the surfaces of the lens optical parts and into the camera itself.
If you don’t use your camera for some period of time (a month and more) remove the batteries from
the camera. Keep the batteries separately in places inaccessible for children.
Load and unload your camera either indoors or in shade protecting it against direct sun light and
bright artificial light.
Always cock the shutter as far as it will go to avoid blank exposures.
Do not keep the camera with the shutter cocked for a long period of time since it is likely to impair
the shutter operation.
Do not try to rotate the shutter speed dial with the index moving along its short section from
“500” to “B”. Do not rotate shutter speed dial when self-timer is running and when setting the
release button in “T” position.
When taking pictures in frosty weather, keep the camera under your
street-clothes but not. in the open air and take it out only for the moment of picture taking.
Since the camera is a complex instrument, its repair and adjustment should be performed in repair
shops only.
