|"When the power switch is turned on and the Ready light does not light |
but "888" begins to blink, an internal memory back-up error has occurred.
If the "step" key and the "input" key are pressed at the same time,
And the "input" key pushed once again, the READY light will light.
At this point the contents of the memory will be completely cleared.
When back-up errors have occurred numerous times, it is possible that
the lithium battery is bad or worn down or that there is a problem with the
main PC board. Remove the main PC board and check the voltage of the lithium
battery. If the voltage is less than DC 2.5 V, replace the lithium
|If it is a 930 and you haven't changed the battery that is probably the answer. Take off the lid of the machine, I think it has about 4 screws and you will see the flat battery. Take it to radio shack and they will be able to tell you which battery you need. Easy to replace.|
Could well be unfortunately.
