Maintenance And Storage - FujiFilm FUJINON FMT Series Instruction Manual

First, read the number displayed when looking in the
direction of the bow, then the number when looking
in the direction of the object; this gives the direction
of travel in relation to the object.
(Keep the binoculars horizontal and adjust the object
to the vertical scale).
Example:
When looking in direction of bow: 210°
When looking at buoy: 240°
Direction of travel: 30° in relation to the buoy
Note: The binoculars may fail to measure the heading correctly while tilted.

Maintenance and Storage

Cleaning the Lenses
Dirt and fi ngerprints on the surface of the lenses diminish visibility considerably,
and, in the event that they are "baked on" by sunlight and left for days without
treatment, can become permanent. When the lenses are soiled, remove dust with
a soft, dry brush, and wipe dirt and fi ngerprints off with a small amount of alco-
hol soaked into a soft, clean cloth. Wipe using a circular motion, from the center
outwards.
Cleaning the Body
If the outer surface of the binocular becomes soiled or wet, wipe with a dry cloth,
be sure the binoculars are completely dry before replacing them in the case. When
the binoculars are used in a salt-air/ocean environment, they should be rinsed in
fresh water before being stowed away.
Storage
The binocular can be used in temperatures between -20 °C and +50 °C. However,
never leave the binocular in particularly hot or cold places, such as cars, summer
or winter. When not using the binocular for any considerable length of time, store
it in a cool dry place.
