Luna Optics LN-DM50 - Manual (Page 3)

INSTALLING THE BATTERIES:
Your night vision unit operates on two 3V Lithium type batteries, known as
CR123 type. Batteries are included with the unit, so once you’ve used up its
power supply please bring them to a local Electronics/Camera store for a
replacement. NOTE: if using rechargeable batteries make sure each battery
voltage is less than 3.3V
To install the batteries, unscrew the battery compartment covers (7), located
on the back of the unit (one on each side below the ocular (6) and install one
battery into each compartment inserting the positive (+) end first. Once the
batteries are inside, replace the covers.
TURNING THE UNIT ON AND OFF:
Your night vision unit has one-touch push-buttons. To turn the unit ON, first
remove the objective lens cover and press the power button (3) once - until
the green light indicator located on the back of the unit lights up. Look
through the ocular – you should see glow. Even if the image is not yet sharp,
the unit is operating. To turn the unit OFF, press the power button again.
The glow will disappear if you turn the unit off correctly. Always replace the
objective lens cover after the unit is turned off and no longer is in use.
IMPORTANT: When turning the unit ON it is normal to see some image
flickering, as the components warm up to display the image. This is normal
and does not affect the unit.
Your digital viewer can also operate from a common wall outlet with the use
of the plug adapter (included). Insert the adapter cord into the DC output
located opposite the Video output (9)
FOCUSING AND OPERATING THE UNIT:
To obtain the sharp image, you must first rotate the ocular (6) in either
direction, until you notice in which position the image is at its best. After
that, rotate the objective lens (1) 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, just
rotate the front objective lens to adjust the distance to the object you are
viewing.
Your digital viewer is equipped with contrast adjustment wheel (5) and
brightness adjustment buttons (2), which allow you to fine tune the image
depending on the ambient light conditions.
You can connect your device to the RCA-type video input on your TV monitor
or a VCR/DVR recorder. Connect the small end of the Video cable (included)
to the Video Output (9) and then connect to the TV/Recorder.
