INSTALLING THE POWER CABLE

The PC-3 power cable is supplied with your Chart. It has a red lead and black lead. Connect your
unit to a 12 volt DC power source. Red cable to a ( + ), black to negative (-). A THREE AMP SLO-
BLO AMP FUSE SHOULD BE INSTALLED BETWEEN THE RED CABLE AND POSITIVE POLE
ON YOUR 12 VOLT BATTERY.
Some boats are equipped with a fuse panel, generally located beneath the console. The power
source can be wired into the fuse panel, HOWEVER IT IS RECOMMENDED THAT THE POWER
CABLE BE WIRED DIRECTLY TO THE BATTERY.
Important: Although your power connector is made to plug in only one way, it can be forced on
incorrectly. N this is done, it may cause damage to your unit. So observe the offset of the power
plug pins and connect it to the control head accordingly.
Note: It is recommended that all cables for your chart (transducer and power) be positioned as far
away from all other wires and controls as possible. It is especially important that these cables be
located away from the ignition system to reduce the risk of interference in the unit.
