There's no general indication for this. You could determine the power source during a few, admittedly contrived circumstances and is probably not what your interested in.mmartinfan said:How do I know when I am running off of AC power on a wall socket off of the car charger. Is there a display to show me?
The first is if the low battery display indicator is lit. If you plug in and this goes away, its a good indication that you're on external power.
The second, included for completeness, is if the batteries are out of the radio. If the batteries are not installed and the radio is on, it must be running off an external power supply.
Other methods of determining power source would require aftermarket accessories (ie monitoring current at the power connector or installing an LED in the charging circuit.
Lame, I know. The question got me thinking about it though.
