I've noticed that intermittently, when I press and hold button 2 to get the time, I don't get a beep, only a report of the time. Also, I seem to be seeing an intermittent failure of the BP to announce when the sleep timer has expired--it just shuts off without any announcement. Neither of these seems to be reproducible on demand; that is, at a given battery level, etc.=20 -- Walt Smith Technical Writer Freedom Scientific BLV 11800 31st Court North St. Petersburg, FL 33716-1805 Phone: (727) 299-6111 or (800) 444-4443 Ext. 1014 Email: WSmith@xxxxxxxxxxxxxxxxxxxxx Check out our webpage! http://www.FreedomScientific.com =20
