What is that tiny little switch on the SRAM card for?
That is the card’s write protect switch similar to those found on floppy disks. No data can be copied to the card if this switch is set to “write protect”. If the write protect switch has been accidentally set you will see “Crd Pro” on the PEM display when you try to copy your data to the SRAM card. This is PEM’s way of warning you that it cannot upload the data to a write protected card.
