I have 3 FI-70 displays (in addition to a TZT9 and TZTL12F). I cannot get the FI-70's to change units-of-measure. When I get to the units page as described in section 4.11, point at the relevant unit (distance) and press the Function key, I get 3 beeps. This happens on all 3 of the units.
What am I doing wrong?
