Re: External Power Supply Selection?

I would run it at 12 if that's all you had. Regulated ? not necessary, has an internal regulator. But, I suspect the regulator will be fairly hot at 12, so I recommend 9. No lower than 9 though, I've noticed that when the batteries slip to 1.2 each , 7.2 is not enough, the display starts to dim. So, a solid 9v.
