How do I clear memory on Sam4s er-290 cash register,on other tills I have removed the battery as well as turning off, but I can't find a removable battery.
Hi you need the "c" key.
First remove the power plug from the mains
Turn the C key to the position after the PGM setting (MC)
Hold the "clear" key down whilst reconnecting the mains plug.
The read-out on the printer should be .........CS
