OPEN WATER APPLICATION
To locate fish, look for treasure or find that perfect spot, simply turn
the camera power ON and drop the Manta camera into the water. If
you’re drifting with the wind or using a trolling motor with the VS820,
attach the supplied trolling fin to the rear of the Manta Camera for
added stability. The internal weight is enough to keep the camera
down while the fin assists in keeping the Manta camera tracking
straight through the water. If the camera becomes hung up, back
up from the direction you were traveling from and slowly try to back
the camera out of the snag. DO NOT pull directly upward with force
unless all other avenues have been pursued.
BATTERY CHARGING
Recharging the battery after every use is recommended. The charger
that was supplied with the VS820 is a 1-amp two-stage DC charger.
To charge your system, simply connect the positive (red) and
negative (black) female connector from the charger to the positive
(red) and negative (black) male end at the battery. Once connected,
plug the charger into a 110 volt AC wall outlet. The LED indicator
light on the charger will be red when the charger is in a charging
mode. The LED indicator light on the charger will turn green when
the charger switches to a trickle charge. The 7.2 amp hour, 12-volt
battery that was supplied with the VS820 system should take about
8 to 10 hours to charge from a completely discharged state.
When the green LED light is on, disconnect the charger from the
battery and wall outlet. If the green LED light does not come on
after 10 to 12 hours of charging time or the green LED light comes
on relatively soon after the charger is plugged in, this may indicate
that the battery will not accept a full charge. If this occurs and your
camera run time is greatly diminished, you may want to replace the
battery with a battery of equal specification.
If your viewing image appears cloudy, fuzzy or the screen begins
to shrink, 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 similar specification. If you
need to remove the battery, unplug the two battery terminals from the
battery. Remove the Velcro strap that is holding the battery in place
and lift the battery out. To replace the battery, place a new battery
into the battery compartment and secure it with the Velcro strap and
re-connect the positive and negative terminals. MarCum does not
