Hi. This is normal when you haven't changed the batteries on time. It no longer has the power to backup the memory when you get a power cut. You can change the batteries now and try to recover the memory if it is still there. MAKE SURE you leave the POWER ON when changing the batteries as there may be enough in them to hold memory but not if you turn power off. Once you have new batteries in it and the FFFFFFFFFF is on display, turn key to Program or PGM mode and press subtotal. It should print out. Turn key back to REG mode and try it
