Adjusting the Monitor Settings
Monitor Screen Adjustments -
The VS620 monitor has four different adjustments that can be made to
enhance the image on the monitor to the user’s preference. (Note: The VS620
has been pre-set with factory defaults for normal viewing.) To access the
settings menu, press the menu key on the digital keypad. The settings menu
will be displayed on the screen (note: if you wait too long before selecting an
adjustment, the menu screen will time out and disappear). To change between
on-screen adjustment choices (Brightness, contrast, sharpness and color),
continue to press the menu key to your desired monitor adjustment option.
The฀selected฀on-screen฀adjustment฀will฀be฀highlighted฀on฀the฀LCD฀screen.฀To฀
change the settings within a selected menu, use the UP and DOWN arrows
located on the far right of the digital keypad. After pressing your selected
menu option, the main menu will disappear from the center of the screen and
your selected menu option will appear on the bottom of the screen. You can
now be able to easily adjust and see the screen adjustments that you are
making. As you select UP or DOWN to make your adjustments, you will see
the numbers of the selected adjustment increase or decrease depending on
the arrow direction you are depressing. To accept the changes, release the
UP / DOWN arrow and settings will be saved. Once the settings are adjusted
properly, the on-screen menu will shut off automatically. Occasionally, you
may find that one of your settings will not adjust. By simply scrolling through
the menu options and coming back to the setting that wouldn’t adjust a
second time, you will automatically reset the internal timer, enabling that
setting to be adjusted.
Brightness - Use the brightness adjustment to change the overall brightness
of a picture. You can lighten a picture that’s too dark, or darken one that’s too
light. Different lighting conditions and water clarity will affect the brightness
of the picture. By adjusting the brightness, the backlight of the monitor will
increase making the picture brighter. This can be helpful when viewing the
VS620 outdoors during daylight hours. Adjusting the brightness can make the
monitor easier to see.
Contrast - Contrast is the difference in brightness between lightest and
darkest tones in a picture. A picture with too much contrast has highlights
(lighter tones) that are too bright and no detail and shadow areas that are too
black. A picture with too little contrast looks dull, with no true blacks and more
grayish highlights. Different water clarities coupled with the amount of light
available will affect the contrast. Adjust the contrast to the desired setting for
the best overall picture.
Sharpness

contrast can give an impression of increased sharpness, so try this first).

Decreasing the color saturation will make the colors look washed out and gray.
