The 600v x 800h super high resolution LCD monitor on the VS825c viewing system
provides for an extraordinarily sharp and clear picture under most viewing conditions.
The daylight viewable monitor requires no sunshield while viewing outdoors. This
makes it more versatile for summer use or while viewing outside on the open ice. It’s
recommended when viewing outdoors, that the backlight (brightness) be increased to
enhance your viewing experience. Although classified as daylight viewable, it is
recommended that you turn the monitor away from direct sunlight. As indicated, the
screen brightness can be adjusted to improve outside viewing but with direct light and
monitor glare it can detract from the picture quality.
The ultra-thin monitor housing is sealed with a rubber gasket and all plug-in
connections are potted to protect the internal electronics from the harsh elements. The
VS800 series LCD systems are considered water resistant. They’re designed to be
used in the outside elements under most conditions but they’re not recommended to
be submerged underwater. While operating in cold temperature’s, the VS825c utilizes
a sophisticated, thermostatically controlled LCD heating element which allows the
monitor to operate at near optimal temperature. You may experience some blurriness
or slow down in LCD performance when you first power up the screen in cold
temperatures. It can take up to several minutes before the screen temperature reaches
the appropriate operating range.
In order to create an ultra clear - high resolution picture, there needs to be a matching
high quality camera. The VS825c uses the best color camera module available; the
Sony Super HAD ultra low lux CCD. This camera offers a 90° angle of view, giving the
user a wide coverage area for maximum visibility.
The Manta camera design matches the high quality Sony Super HAD color CCD
camera to adjustable high intensity white LED’s. This lighting option incorporates
MarCum’s exclusive Darkwater lighting technology. Darkwater technology greatly
reduces particulate reflection and increases viewing distance by positioning the lights
above and behind the actual camera lens.
Adjusting the settings on a monitor has never been so easy. The digital keypad
activates an onscreen display for making adjustments to the monitor brightness,
contrast, color and sharpness. In addition to adjusting the monitor screen settings, the
digital keypad also controls underwater lighting, dimmer for controlling underwater
lighting intensity and power ON / OFF.
To clean the monitor screen, use a cleaner recommended for plastic and a soft cloth
towel.
