electronic device, intended for examining objects and orientation at
nighttime or under dark conditions. The unit utilizes 2 (two) image
intensifiers which amplify available moonlight, starlight or man-made
light. The binocular was designed to be easy to use, and provide many
years of operation.

6.3 Operation at Night
Take off the lens covers (7) from the lenses (6). Turn on the device
by pushing and holding the “On” button (4). In case of insufficient
lighting when observing an object which is situated not far from
the viewer, turn on the infrared illuminator by pushing and holding
the button (3). As soon as the “I/R On” button is released the
infrared illuminator turns off.
Note: The illuminator will be activated only if the unit has
been already switched on by the button (4).
Note: If you look directly at front of the binocular when
infrared illuminator is on it appears as a red dot at a size of a lit
cigarette. The illuminator can be also detected using night vision
device. Therefore, if you need to remain undetected, use the
illuminator with caution.
Note: The unit automatically turns off after few minutes. This
feature can be used to economically utilize the batteries power by
periodically switching on and off the device during operation.
If brightness of the screen decreases, replace the batteries. Put
protective lens caps back on the lenses after operation. If you don’t
intend to use the device during long time remove the batteries
from the battery compartments to avoid any damage of the device
in case of occasional leakage of electrolyte from the batteries.
