This message serves as a warning! Today I received one of the new yellow smartcards to replace the blue one in one of my 508s. The replacement went fine and dandy, with the programming tuned back on within the stated time. However, (and stupid me, I didn't even think to check), the smartcard replacement blew away all of the timers that I had set on that 508, so nothing recorded tonight. When I pull up the timers screen on the 508, I have 7 timers listed there, 6 of which are for the same event on the same channel. The other 12 timers that I had set are now gone. So, if and when you are instructed to replace your smartcard, make absolutely sure that you know what timers you have set, and CHECK THEM AFTER THE REPLACEMENT!
