how do you default ram on samsung er-4915 ?

how do you default ram to remove old programming in a samsung er-4915 register? removing battery does not work. when powered back up error tone happens. also power up using 00 in service manual does not work either. please advise.

Oh dear, it's never a good idea to try to remove the battery, and clear everything. You often make a lot more work for yourself. It would have been much better just to have edited the old prog.

Anyway, if you have done that, then you must RAM clear it and start again.

Powering up the machine in S modewith 00 held down should have worked. Make sure you hold it long enough. Most models print when cleared. If it doesn't work, what can you see on the display when you try the procedure?
