Panasonic UD-716 badge reader

[David Arnold <cotteril@sghms.ac.uk>]

Recently we have had a couple of false high dose readings. Readout of 
the backup elements fails to confirm the doses and the wearers' 
of the badges confirm that they have done nothing out of the ordinary, 
work wise.

Has anyone out there had similar experiences of spurious dose 
readings?  Any comments/explanations welcome.
