Can I program any thing while the "Program Mode" is closed?
I have Samsung SAM4s ER-5240M, it was given to a customer, but they can't sign on. We're assuming the previous owner used a "coded sign-on" function?
I was told I can change it, but every time I press a key "sequence error" pops up.

Please help.

Regards,
Yvonne

You may be correct on the coded sign-on. Personally, I would recommend that you MAC (Memory All Clear) the register to return it to an out-of-the-box state and then reprogram it. This will ensure you don't inherit any undesirable option (or other) settings from the previous owner. If you have the manual, the procedure is on pg. 78 and you will need a Service (with a 'C' stamped on it) key to perform this procedure. If you don't have a Service key, you'll have to take the register to a dealer and have it done.
