P7100 help wanted

Hi all,

I've had my P7100 for about three weeks now, and so far I'm very pleased with it.

However, despite studying the manual in some detail, I've not been able to select the multishot 16 or interval timer modes from the menu in PASM modes. I am allowed to select single, continuous, continuous w. flash and BSS, but not the remaining two options.

Does anyone have any idea what is going on, what kind of setting might be preventing me from selecting either option?

Thanks in advance!
