Auto-Positioning in TREK1000 / DecaRangeRTLS does not function

[color=#222222][size=small][font=Arial, Helvetica, sans-serif]The title says it all - almost. In
the beginning auto-positioning
functioned, now it doesn’t do
anything: the anchors do not
change their position at all.

Any clues?

Thanks,
