base of the monitor) by turning each one counter-clockwise. Make sure to loosen the knobs a considerable distance. Than depress both knobs by pushing inwards and hold in place. This releases the lock on the monitor angle. While depressing the knobs with the base of your palms, use the index fingers of each hand and gently lift the monitor up to the desired viewing position and release tension on the gimbal knobs. Once you have set the monitor to the desired viewing angle, gently tighten the knobs until they are snug. The battery, camera and cable are now accessible behind the monitor. It’s easiest to remove the Velcro straps and unzip the soft pack case. The battery cable connectors can now be connected to the battery by attaching the corresponding wire colors to the correct terminal. The positive (red) wire from the monitor can be connected to the positive (red) terminal on the battery. The negative (black) wire coming from the monitor can be connected to the negative (black) terminal on the battery. After the terminals have been connected, the VS825c is ready for use. (Note: The battery leads should stay connected at all times other than while charging. This will be covered later in the charging process.)
To turn ON the VS825c, press the power key which is located on the keypad on lower left side on the front of the monitor. After pressing the power key, a small red LED indicator light – located next to the power button - will turn ON. The monitor should now be displaying the image being transmitted from the camera. The camera can now be unwrapped from the cable spool and deployed into the water to the desired depth.
The depth of field (distance the camera can see underwater) depends on the clarity of the water and available light at the depth the camera is used. In clear water, the depth of field can be many feet but in cloudy or muddy water the depth of view can be reduced to only a few inches due to particles suspended in the water. Dirty or muddy water and/or low light penetration can detract from the quality of the color picture. Optimum color quality will result from clear water and adequate light penetration.
Adjusting the Monitor Settings
The VS825c monitor has four different adjustments that can be made by utilizing the on-screen display. These adjustments can be made to enhance the image on the monitor to the user’s preference. (note: The VS825c 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, color, sharpness), continue to press the menu key. 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. You will see
