Battery Charging
Your Marcum system comes with a 3-stage battery charger. This style of
charger has proven to be the most effective and easiest to use of all charging
systems available. While the rate of charge is low, a completely discharged
batterycanbebroughtbacktoafullchargeinaslittleas12hours.Because
this is a 3-stage charger, there is no danger of overcharging your battery.
Therefore, it is recommended that you charge your battery overnight after
each use, and once every few months during periods of non-use.
A 3-Stage charger works like this—

Some common sense safety tips:
For safety reasons, it is recommended that you place your system on a flat,
hard surface like cement or tile when charging it, away from any flammable
materials. Be sure to disconnect the charger from the wall when not in use,
andavoidleavingyourbatteryhookeduptothechargerforextendedperiods
of time.
To charge your battery:
Your battery has a wiring harness attached to it that has “piggyback” termi-
nals on it, enabling you to keep the power cord from the monitor attached to
the battery at all times, as well as having the wiring harness with receptacle
for your charger attached at all times. To charge, simply couple the end of
the charger with the end of the wiring harness and once connected, plug the
transformerendofthechargerintoa110voltACwalloutlet.Youwillsee

battery and wall outlet. However, no harm will come to your battery if you
leave it attached to the charger.
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 of similar specifica-
tions 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 VS620 in a relatively warm
environmenttominimizetheuseofthebuiltinLCDheatersystem.Bystarting
