DC Power Connection
If the user desires to operate the Bathy-500MF from a
D.C. source, any battery or supply in the range of 11 to 30 volts may be used.
No selection of the input voltage need be done as the power supply of the unit
will regulate automatically over the stated voltage range. The user need only
connect the P/N P01182 D.C. Power Cable Color-coded battery clips (red =
positive +) are factory installed on this cable assembly. If cable replacement
is required refer to the diagram below.

11-30 volts D.C. (1.5 amps @ 12 v. 0.5 amp @ 30 v.)
