FOCUSING THE UNIT:
To obtain the sharp image, you must first rotate the objective lens (1) in either
direction, until you notice in which position the image is at its best. After that,
rotate the ocular (2) 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.
BRIGHTNESS ADJUSTMENT:
Your digital viewer is equipped with dual brightness control. An automatic
brightness control sensor adjusts the image brightness according to the
available ambient light. In addition a toggle brightness adjustment wheel (14)
allows you to fine-tune the image brightness depending on the ambient light
conditions. Please note that during daylight you will need to tone the
brightness down to avoid image flickering and to preserve the battery life.
During nighttime you could increase the brightness all the way up, however
when utilizing built-in or external IR illuminator, you may need to tone the
brightness down a bit. Each rotation of the wheel in either direction will
decrease or increase brightness by one level.
ELECTRONIC IMAGE MAGNIFICATION ZOOM:
Your unit is also equipped with electronic zoom function, which allows you to
change image magnification from 5x to 25x on model LN-G2-M44 or 6x to 30x
on model LN-G2-M50. To increase the image magnification press the IMAGE
button (11) on the + side and look into the ocular – you will see the image
magnification increase. At the minimum level (1.00) the image magnification is
5x (6x for model LN-G2-M50); at the maximum level (5.00) the image
magnification is 25x (30x for model LN-G2-M50). You can see the zoom level
either in the left or right lower corner of the image screen (depending on the
software version) once you start pressing the IMAGE button on the + side. To
decrease the image magnification, press the IMAGE button on the – side.
USING INFRARED ILLUMINATOR / IMAGE COLOR OPTIONS:
Your digital viewer is equipped with a built-in powerful Infrared illuminator
light (10). This light operates in a spectrum, which is normally invisible to a
human eye, however with the help of the CCD sensor, located inside the unit,
you will see a beam of light when looking though the ocular lens. Since the
CCD does not actively amplify the available light, you will need to utilize the IR
illuminator often in the nighttime conditions.
To turn the Infrared illuminator ON, press the Infrared illuminator button (13)
momentarily – the illuminator will turn on and red LED light indicator located
