Can you supply a brand name? On a SAM4 920, one can turn the control key to the program position, hold the sub total key depressed and cycle the power off, while still holding the subtotal key down, cycle the power back on. This is called an Initial Reset, and will unlock a previous condition. One needs to avoid what ever they did to cause this Add Check error. Any feedback??
