The BC-300 has an 1-year calendar function for storing schedules in the data bank.It's neccessary to set the beginning month
first befor using it. Press 5 times the command key to see the current beginning month. Now press EXE month / year EXE to set
the new beginning month.

Thank you very much for your answer.

I try to put the date like this:

COMMAND > CALENDAR 0/0000 > EXE > SET MONTH/YEAR? 06/2011 > EXE

The computer go out of service , the cursor stop to blink, I push any key without response.
May be the computer is wrong, what you think about it ?

Thank you

Have you tried to reset the BC-300? If not press the RESET button that's hidden behind the back cover.
After resetting the beginnig month should be 1/1986. If you want to use the calendar to see the weekday
of a given date, just type in month/day CALENDAR. Use the up and down keys for going back and forth
by 1 day. Sometimes the calculator freezes for some seconds while going back.

The problem was the small memory battery voltage at 2.8 v instead of 3.0 v.
I change it and reset the calculator as you suggest and instantly appeared the date 1/1986.

So if I pay your work, can you e-mail me a copy of your manual ?

Thank you
