Welcome to EpoS Wizard!
Hi Epos Wizard,
Please Could You Help With A Problem That I Have With My Casio TK-T5OO.
The Problem Is That My Casio Has Locked Up & Has Been Locked Up For Some Time.
On The Screen It Shows FFFFFFFFFF - What Does This Mean? 
Look Forward To Hearing From U Very Soon

Hi Charlie 
It sounds like your Cash Register is stuck in the middle of doing a Reset.
If you turn the power off, Turn the key to the PGM position
and turn back on.
then when the 'FFFFFFFFFF's appear press Subtotal - A small printout should be done and it should be up and running again.
Hope this works for you, let me know if not.
Regards
