Same here with a just purchased DM-15L (M1B V21 S/N# 01248). At 48 MHz it works flawlessly.

A question, the ON+1/x string reports, after the battery voltage, the letters "RTC". What do they mean? Evenmore, there's a piezo buzzer inside. I suppose that RTC means "Real Time Clock" and that both it and the buzzer are used in the DM-41L incarnation of this hardware but, are any of them accessible from the 15L software?
