When you get home from a trip, put your battery on charge right away and
leave it there overnight, or for around 8-12 hours. Likewise, on the night before
an ice fishing trip, put it on the charger again, just to make sure. Again, there
is no danger of overcharging your battery. We often talk to people who
hesitate to charge their battery after each use for fear that the battery will
develop a “memory” and this will lead to a shortened run time—THIS IS
FALSE!!! ALWAYS CHARGE YOUR BATTERY AFTER EVERY USE!!! Be
sure to use the charger that came with your system, or a similar one that is
between .5 amp. and 1 amp. Using a larger charger, like you would use on a
car, truck, RV, or boat is likely to cause damage to the battery. There is really
no danger of overcharging your battery with a low amp charger, and most
chargers automatically go into “maintenance mode” once a full charge has
been achieved.
TO CHARGE YOUR BATTERY:
Your battery has a wiring harness attached to it that has “piggyback” terminals
on it, enabling you to keep the power cord from the unit 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. It is normal for a green light to appear on
the charger at this time if the charger is plugged into the battery only. It is also
normal for the light on the charger to be green if it is just plugged into the wall.
When it is plugged into the wall and battery, you will see a red LED light
appear on the charger. If the light is red, the battery is being charged. When
your battery is fully charged, this red light should change to green. If it is time
to go fishing and the light has not turned green, go fish and try to allow a
longer charging period next time.
Batteries are an expendable item, and must be replaced periodically. The
batteries that we use are the “Sealed Lead Acid” variety, they are 12 volts, and
range from 7 to 9 amps. The more amps the battery has, the longer it will run
on a full charge. Your Marcum can be powered off of any battery that is 12
volts, even a large automotive or deep cycle battery.
If you are having difficulty with the charging process, please see the Charger
Troubleshooting section at end of the manual.
If you need to remove the battery, slide the power cord leads from the battery.
Remove the strap that is holding the battery in place and lift the battery out. To
replace the battery, place a new battery of similar specifications into the
battery compartment and secure it with the Velcro strap and re-connect the
positive and negative terminals.
SETTING THE TRANSDUCER FOR ICE FISHING
:
When used in conjunction with the retractable pivoting transducer arm and
rubber stopper, the Digital Sonar’s transducer will automatically level itself in
your ice hole. To begin operation, take the transducer out of the recessed
holder, and rotate the adjustable ice arm out from inside the shuttle. Extend
the transducer arm, (the cable should already be threaded through it with
stopper in place) and deploy the transducer into the water. We recommend
setting your stopper to have the transducer down the least amount possible.
The Marcum Digital Sonar puts out enough power that in most cases it is not
necessary to have your transducer down more than a few inches below the
