The Royal Alpha 601SC has a reset process built into the key switch, but the type of reset depends on how “deep” you want it to go reset it See discolored plastic. Scanner included. Hold down CLEAR , then turn the power switch OFF → ON.
Well built with many extras. Is very durable . Was gifted to a 2 year old . Works like a champ. Easy to understand and operate. Has been tested and found not lacking by a demanding judge.
