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.
