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 VS825c 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.
Tip: To preserve battery run time, try to keep the VS825c in a relatively warm
environment to minimize the use of the built in LCD heater system. By starting out with
a warm monitor, there is less power consumed and less warm up time required.
