4. To focus, first utilize the eyepiece-focusing ring to bring the
image into approximate focus, then fine focus with the
objective lens focusing ring. If only (1) focusing mechanism
is present on your unit, then simply focus as necessary.
5. Batteries are not included.
Things to remember
1. The purpose of the pinhole at the center of the lens cover is
to dramatically reduce ambient lighting and thereby simulate
a nighttime environment. The unit can thus be tested during
the daytime with the lens cover in place. However, activat-
ing the unit during the daylight without the protection of the
lens cover will cause too much light to hit the intensifier and
can result in permanent damage. There is a built-in “anti-
bloom” function to protect against such an event, but if the
unit “flashes” upon being activated in a well-lit environment,
it may require several minutes for the instrument to re-set
itself before it can be used.
2. You may see very small black spots in your field of view;
this is common to many night vision devices. However, such
spots will not increase in size nor will they affect optical
performance.
3. All Famous Trails night vision devices are covered by a one-
year limited warranty. Please see the enclosed warranty card
for more information.
4. Finally, please treat your Famous Trails monocular as you
would your camera or binocular
