When I returned to my house after letting it out, and switched on the Panasonic Dimension 4 The Genius, I cannot stop the beeping which scrolls through on "HI" mode from 10, 20, 30, 40, 50, 60, 70, 80, 90. I can temporarily stop it by clicking twice on Stop/Reset. However, I cannot proceed with activating any other function or the "HI" mode scrolling and beeping resumes. Please advise how to resolve
