Thiscan causethe Focusunit tooverheat and affect performance.
Whenusing Focusinan automobile,boat, oron otherDC sourceswiththe UniversalAC/DC powersupply,makesure
that the vehicleisstarted and running beforeconnectingthe Focusunit. If the DC powersupplydoesnot illuminateand
requiresresetting, disconnect the DC powersupplyfromthe DC outlet, restart yourvehicle, and then reconnect your
DC powersupplyintothe DC outlet.Failuretofollowtheseinstructionscan resultinthe powersupplynot supplying
powertoFocus.
Whenthe automobileinwhichyou areusing the Focusunitisturned off,disconnect and removethe unitfromthe
