Just an clarify what I had written:
My battery low (beep as well as the battery icon) would come on even though the batteries were charged. When I went into the GLOB settings and checked the battery info, the readings looked OK, yet the low battery indicator was coming on. I did the reset and that took care of the problem.
I was thinking that perhaps I had somehow changed the warning threshold levels but that's not the case because I sent down the same exact information as I had backed up, and after that reset all was OK.
As mikey60 wrote, the battery charging indicator will blink when the radio is on, to indicate that the charging circuit is active. That setting has to do with the amount of time the PSR-500 is supposed to charge the batteries, based on the GLOB setting.
Speaking of battery levels, somebody else had posted (different thread) on just what the readout means for the battery level (for example, 597 and 5.32v). I read it a few times and still don't get it. They wrote that the 597 type of number is a "digital" number. What do these readings mean, and how can it be that the reading is 5.32v yet the 4 AA cells are 1.2 volts each? (1.2 x 4 = 4.8)?
Thanks in advance.
