Care Instructions - Leica M Operating Instructions Manual

EN MONITOR
The monitor is manufactured using a high-precision process. This
ensures that of the total of more than 921,600 pixels only a very
small number will not work correctly, i.e. remain dark or always be
lit. However, this is not a malfunction and it does not impair the
reproduction of the picture.
• If the camera is exposed to significant temperature fluctuations,
condensation can form on the monitor. Wipe it carefully with a
soft dry cloth.
• If the camera is very cold when it is turned on, the displays may
at first appear darker than usual. As soon as it warms up, it will
reach its normal level of brightness.
SENSOR
• Cosmic radiation (e.g. on flights) can cause pixel defects.
CONDENSATION MOISTURE
• If condensation has formed on or in the camera, you should turn
it off and leave it to stand at room temperature for around an
hour. Once the camera temperature has adjusted to room
temperature, the condensation will disappear by itself.

CARE INSTRUCTIONS

As any soiling also represents a growth medium for microorgan-
isms, you should take care to keep the equipment clean.
FOR THE CAMERA
• Clean the camera only with a soft, dry cloth. Stubborn dirt
should first of all be covered with a well-thinned cleaning agent
and then wiped off with a dry cloth.
• To remove stains and fingerprints, the camera and lenses should
be wiped with a clean lint-free cloth. Tougher dirt in hard to reach
corners of the camera body can be removed with a small brush.
The shutter blades may not be touched when doing this.
• All mechanically operated bearings and sliding surfaces on your
camera are lubricated. Please remember this if you will not be
using the camera for a long period of time. To prevent the
lubrication points becoming gummed up, the camera shutter
should be released a number of times every three months. It is
also recommended that you repeatedly move and use all other
controls. The range and aperture adjustment rings on the lens
should also be moved periodically.
• Take care not to scratch the sensor for the 6-bit coding in the
bayonet fastening (see p. 121), or to get it dirty. Take care also
that no grains of sand or similar particles enter the fastening,
where they could scratch the bayonet. Only clean this compo-
nent when dry and do not exert any pressure on the glass cover.
