Connectors located on top of the monitor receive the following
cabling and components:
Ultrasonic depth sensor
Doppler velocity sensor
Pressure depth sensor

Battery Pack
The 12-volt battery pack, mounted to the bottom of the chassis,
provides the power for operating the monitor and maintaining the
monitor memory through the power supply on the processor board.
The monitor measures the battery voltage, and the FieldScan and
Profile software applications provide a user-defined setting to
ensure the monitor signals a warning when the available power is
low.
External Power
The 4000 monitor also can receive power from an external DC
power source when equipped with a special conversion kit.
External power requires a power source running between 9 and 14
volts at 1 amp of continuous current.
