Marcum Technologies VS560 manual Battery Charging, Directional Viewing Indicator

BATTERY CHARGING

Recharging the battery after every use is recommended. As a general rule of thumb, charge the battery for twice the amount of time as it was used. The VS560 underwater viewing system has a DC charging port located just above the battery door on the right side

of the monitor face. The charger that was supplied with the VS560 system is a 500 mA DC charger with a male jack. To charge your system, simply plug the male jack of the charger into the plug in port in the face of the monitor and then plug the charger into a 110 volt AC wall outlet. The 7-amp, 12-volt battery that was supplied with the VS560 system should take about 15 hours to charge from a completely discharged state. The charger incorporates a Charge Alert feature to alert the user to when the battery reaches full capac- ity. This is accomplished when the green LED light shuts off on the face of the charger. The charger DOES NOT shut off automatically but will output a trickle charge indefinitely.

However, it is recommended that the charger be disconnected from the moni- tor when the Charge Alert green LED is no longer on. It is also recommended that you remove the battery door while charging to allow for increased air ventilation through out the battery compartment.

If your viewing image appears cloudy or fuzzy, check your battery charge. One of the major symptoms of a dead or near-dead battery is the degradation of your viewing image. Try charging your battery or if the battery is unable to hold a charge, replace it with a new one of the same specification. If you need to remove the battery, unplug the two battery terminals from the battery. Unscrew both the screws located in the upper right and left corner of the battery compartment. This will allow you to remove the battery strap from the battery. After removing the strap, lift the battery up slightly with a finger on either side of the battery and slide the battery towards you. This should allow for easy removal of the battery. To replace the battery, lift the battery up and slide into the battery compartment until the front of the battery drops down into the compartment. Replace the battery strap by using the two screws supplied and tighten until moderate resistance is felt.

DIRECTIONAL VIEWING INDICATOR

The viewing direction indicator is located in the upper left-hand corner of the monitor screen and utilizes an icon shaped as an arrow to indicate the direction the camera is pointing. This is accomplished by the use of two magnetic compasses that talk back and forth through software that continuously calculate the differential.

There are two very important criteria to make the system work accurately: 1) The monitor and camera must be level. The sensors will not accommodate an angle greater than 10 degrees. Therefore the monitor needs to be flat on the ice to work properly. If the monitor is sitting at an angle of more than ten degrees, than the viewing direction shown will not be accurate. The camera when hung by the cable will be accurate. However, if you hold the camera in your hand and are rotating the camera, it may not be level and therefore you will notice an inaccuracy in the viewing indicator; 2) The sensors that are located in the monitor and camera are affected by metal. Like any compass, metal can cause the magnetic sensors to be become inaccurate. When using the viewing indicator, make sure the monitor and camera are not located near any metal objects.

The viewing indicator utilizes eight different stop points in calculating viewing direction. As a result of the limited stop points, there may be some inaccuracies that result when the camera falls between the various stop points. If used properly, the VS560 system provides an excellent reference for determining relative viewing direction.
