Marcum Technologies LX-3, User Manual

Page: 7 / 11

To check the location, press either the UP key or the DN key to
activate the visual blinking lights to reacquaint yourself with the
location. The blinking yellow lights only assist you in setting the
location and act as a visual reference.
The benefit to the MarCum design is that it allows you to move
your Zoom window between surface and bottom, and in turn
Zoom in on any 5- or 10-foot section of water (on the 20-foot
depth Range). There are many species of fish that are not bot-
tom huggers that we all enjoy pursuing. Crappies, sunfish, perch,
tullibies, whitefish, trout (rainbow, brook, brown, etc.) as well as
lake trout are not bottom huggers and often suspend anywhere
within the water column. The MarCum design allows you to have
two sizes of Zoom window per depth Range and position the
Zoom where you need it for the fish that you enjoy pursuing.
Deluxe Ice System Only
The “Deluxe Ice System" comes with some additional features
that require further explanation. Included in this system are a
high-quality 600 x 600 PVC-backed denier soft-pack carrying
case, ABS electronics shuttle with recessed trays for transducer
and battery, 12-volt/7-amp sealed lead acid battery, Digital
Charging System (DCS), power cord, LX-3 sonar unit, self-
aligning transducer, and gimbal bracket with mounting knobs.
Digital Charging System - The “Digital Charging System”
(DCS) is another MarCum Technologies proprietary design. This
product was designed to address the need to both accurately
monitor batteries while in the field as well as provide a battery-
friendly charging and maintenance system. The DCS utilizes a
small LCD panel to display battery charge remaining in incre-
ments of 10 percent. To utilize the charging and maintenance
function of the DCS, plug the male DC jack from the 1-amp wall
transformer into the female DC receptacle. Then plug the wall
transformer into an AC outlet. The LCD panel should display a
flashing percentage and the letters “CHRG” should appear,
indicating the system is in the charging mode.
The DCS is a three-stage charger providing an initial bulk rate
charge, slowing to an absorption charge, and finishing and main-
taining with a trickle charge. This sophisticated charging and
maintenance system allows you to leave the battery unattended
without concern over damaging effects from overcharging.
