HP 17 B ii - how to fix date setting ?

With switch in set position hit date. Hit the date button (X) and then enter the year in (4) digits (ie:2013) then hit the (X) button. This will enter the year. Enter the month and day in (4) digits (ex: 0615) and hit the (X) button again. This should set the date for you..ie:6/15/2013!!!!! For time in set position enter time (ex: 346 and hit PM button if afternoon and then press time. This should give you 3:46pm. Hope this helps.

Sorry, boss.

But getting standard deviation from a probability distribution would probably be best done by hand (of course, with the use of a computational device for those hard-to-reach fractions).

If your distribution question has a long line of events (IE, data points) then you'd probably want to use a more advanced calculator.

Nevertheless....I will return this afternoon with a more informed answer after I tinker with my BA-II Plus.

Whenever I do these, though, I usually pop open my TI89 Titanium (or of course just do it by hand).

STAY TUNED, MO...

You've input an invalid date, for example the month greater than 12 or the day greater than 31. The BA-IIPlus can handle dates in two different formats, the US MM-DD-YYYY and the European DD-MM-YYYY formats. Make sure you enter the date in the proper one. You can see current the format by pressing 2nd [FORMAT] down-arrow down-arrow and change it by pressing 2nd [SET]. Press 2nd [QUIT] when done.

I'm going to quote dsteele04 on this one (he is a user of this site).

1. Switch the GT*RATE SET button to RATE SET.
2. Press the date/clock button to display current time.
3. Enter time wanted using military time. 4:52 p.m would be entered as 16.52 (Note the 16 is followed by . then enter the 52. (ie. 10:45 a.m. would be entered as 10.45)
4. Press the date/clock button again to enter new time.

Just reset mine and is current. If the built in battery needs changed, access panel is on the back. It uses a watch type battery.

Setting the date:

1. Press the CALENDAR/CLOCK Key. The default date will appear.

2. Hold the TIME SET key down for 3 seconds or until you see the first
digit begin to blink in the display.

3. Input the correct date.

4. Firmly press and release the TIME SET key. The first digit should
stop blinking and the date is then set.

Setting the time:

1. Press the CALENDAR/CLOCK key. The default time will appear.

2. Hold the TIME SET key down for 3 seconds or until you see the first
digit begin to blink in the display.

NOTE: The seconds will disappear.

3. Input the correct time. If you need to adjust to AM or PM, press
the AM/PM accordingly.

4. Firmly press and release the TIME SET key. The first digit should
stop blinking and the time is then set. The seconds will again be
displayed.

Follow by pressing the CLEAR key to return to the calculator mode. To
return to either the TIME or DATE, press the CALENDAR/CLOCK key to
toggle between them.

NOTE: If unsuccessful attempts to set the date and time have been made,
please first confirm that the piece of paper/plastic in the battery
compartment on the bottom of the unit has been removed. Then reset the
unit by inserting the tip of a ball point pen into the "RESET" hole on
the bottom of the calculator. The calculator should be on and in the
"Print" mode so that you can hear the calculator reset.

Are you talking about TVM calculations? If so, you need to change your payments per year setting (P/Y) from 1 to 12. That should fix it. Hit 2nd, (I/Y), 12 and then ENTER.

I'm not positive because I pushed several buttons just trying to get it set and stay set -- but I think I did the following: fist push the "time set" button, ie the "memory plus" button then push the "format" button, ie the red "minus" button to change the settings -- continue until you have set the date and time -- then when you are finished you have to push the "time set" button, ie the "memory plus" button again to set it in place -- at least I think that's what I did
