Date/Time I have a brand new 30D and the days of the month only goes up to 12 and then starts back at one....how can this be fixed?

There are many models of Centrios brand alarms.

Here is some advice found on the web
1:
All buttons are on the back of the clock. To set the time zone, push "menu"; then push "Set" until the correct time zone is displayed (EA = Eastern, PA = Pacific, etc); then push "Menu" again - DONE. To adjust time, date, year & day, push & hold "Set" until the hour begins to flash; then push "Adjust" until the correct hour is reached; then push "Set"; repeat this sequence as the clock moves on to the next flashing segment (e.g. minute, seconds, month, date, & year); the clock will automatically set the Day based upon the Month, Day & Year you select - DONE.
