I picked one up used and am having a heck of a time trying to get the date/time adjusted. I can get to the screen by pressing the set/sel button but can't seem to access the day/year/date/etc.
I've got one. When you press the SET/EL button are you holding it for a few seconds until the seconds are blinking? Press MODE to scroll through the hours, minutes, days, etc...using VIEW to advance to the proper time. Once all is set you can press the SET/EL button to exit out and move onto the other screens.
