Doh to both. Thanks. I took "data" to mean the MSL, not the literal "data"!
And yes, "Software version" says LS980ZVD.
Happy Monday, now to see whether it helps.
Interesting: when I went to change BSRTimer, it showed 3000 but when I selected it, 3 was entered as the value, i.e., as if that was the current setting. I cancelled out to be sure, and it did indeed say 3000, then 3 again when I selected it. I saved it as 3, rebooted, and now it shows 3 in both places. Makes ya wonder--does something think it *should* be 3 (besides the posts here!)? Of course I'll never know, now that I've set it to 3. Kind of reminds me of the chronic Windows bug (which, hmm, I haven't seen in a while, but saw repeatedly for at least a decade) where some dialog setting shows one value, but behavior suggests it's another, and the fix is to set it to the other and back to the alleged current setting.
Anyway, thanks to y'all's info, I have set it and can now reset it if I think that was Bad (not expecting that, of course, but it's always good to know how to get back where you were).
