[time-nuts] Ashtech Z12 question.

[Mark Sims]

I just added support for the Z12 to Lady Heather and fired up my Z12 for the first time in a few years.   It powers up in some kind of a weird loopback mode and you have to reset the receiver memory to get it working.   

Does the Z12 have an internal memory backup battery?   Mine is currently doing a long L1/L2 RINEX capture and I can't open it and check right now.
