Turned scanner off last night got up and turned on this morning all I get is "sd access card error" can even get sentinel to get to server any suggestions beside send it back it about 2 months old.
I think the problem comes from turning the scanner off after leaving it on for a long time. I had my 2 536s on for months, and ran into the SD access error when I turned the scanners back on. Two scanners bricked in a matter of a few days by turning the scanners off then on again. Yeah, I think I'm over having my scanner depend on an SD card to operate.
A replacement card is $11 or less, and it only takes a few minutes to copy your scanner settings and favorite lists to a new one. Have a spare card on hand, ready to go.
