Luna Optics LN-ERS45M - Manual (Page 5)

INSTALLING THE BATTERY:
Your night vision unit operates on one 3V Lithium battery, also known as
123type. It is also possible to operate this unit on one standard AA-type
battery by removing the internal part of the Battery Compartment
Cover (1). Please note that when unit is operating on AA-type battery,
the operating time will be reduced compared to the 3V Lithium battery
(see technical specifications).
To install the battery, remove the Battery Compartment Cover (1).
Install the battery according to the diagram indicated on the compartment.
Once the battery is inside, replace the cover.
Your night vision scope is equipped with a special Light Indicator (6),
which lights up green during scope operation, however, when the battery
is low on power, the same indicator will turn red, indicating it is time to
change the battery.
TURNING THE UNIT ON AND OFF:
Your night vision unit has a 3-Mode ON/OFF/Standby Switch (2), which
combines the function of turning the unit ON and OFF, as well as putting
the unit in a Standby Mode (only usable with the Remote Control Pad
attached). To turn the unit ON, first flip the Protective Lens Cover (13)
up (ONLY IN THE DARK!) and rotate the Power Switch (2) down one dial
to ON position. The Light Indicator (6) will turn on green. Look through
the Rubber Eyecup (5) – you should see the green glow. Even if the
image is not yet sharp, the unit is operating. To turn the unit OFF, flip the
power switch one dial back (up) to the OFF position. The green glow will
disappear immediately indicating the unit is in OFF mode. Always replace
the protective lens cover (13) after the unit is turned off and no longer is
in use.
FOCUSING THE UNIT:
To obtain the sharp image, you must first rotate the Ocular Focusing
Wheel (4) in either direction, until you notice in which position the image
is at its best. After that, rotate the Distance Focusing Wheel (12) also
until the image is at its best. You may have to repeat the process again,
until the image is sharp and clear. Once the clear image is obtained, you
no longer need to adjust the Ocular Focusing Wheel, just rotate the
Distance Focusing Wheel to adjust the distance to the object you are
viewing.
OPTIONAL INFRARED ILLUMINATOR:
The LN-ERS45M scope features an Image Intensifier Tube of Generation-
2+, which has enough light sensitivity to function outdoors without the
help of the Infrared Illuminator. It may however be beneficiary to
purchase an extended range IR illuminator for long distance shooting or
