Chad, Chad, Chad, sooo lemme git diss straight "You have fried your cousins scanner not yours
by thinking to feed 12V power into the PC/IF jack on the front panel would be a gQQd idea ?
Dude are you serious ??? Also, Radio Shack DOES CARRY replacement power adapters
for the Pro-197 and DONT LET ANYONE TELL YOU DIFFERENT ! Take the scanner in with
you and if one RS associate cannot stroll over to the AC Adapters and select the proper
adapter AND the correct "adaptaplug" free tip that comes with it ~ jump to the next associate

Remember, this is VERY important that the AC Adapter's tip plug be alligned to be "Tip Positive" !
ps ~ So you took an 1/8" headphone jack type cable then stripped one side of it to bare wires
then decided the see if a $424.99 Digital Scanner would power up that way instead of the jack
in the back of the unit marked "Power" ? Maybe because you didn't have a T-Type plug adapter?
btw~You are not communicating clearly when in one of your last posts you make the statements:
"Had got it working finally this morning after most of the day yesterday on it" and then this"
"It was a car charger" are you saying it's fixed now and that the car charger was the problem ?
.
Bottom Line: By telling us everything ... your "Helping Us ~ Help You" that's how the forum works !
