I have a Lowrance 3100 in-dash gauge that keeps the hours, volts, Air / Lake temp, Time of day, etc. I don't have the manual, and I can't find it online anywhere. Anyone know how to configure this device? I'm looking to set the time correctly (cause it was lost when my batt went dead) as well as get the hours synced up with the analog meter on the engine. Thanks, John
