Hoe to I get my hp 12c calculator to show the begin/end format? It did, now when o hit "g" "7" beg or "g" "*' end, can not get to display? Thank you !


Begin mode is obtained by pressing [g][7] and it should then show BEGIN in the bottom line of the display. End mode is obtained by pressing [g][8]. End mode does not not show an indicator in the display because it is the default mode, so if BEGIN isn't showing, then the calulator is in End mode.

The calculator is not showing any display after replacing the battery of HP 12C


Try verifying Proper Operation (Self-Tests)

If it appears that the calculator will not turn on or otherwise is not operating properly, use one of the following procedures.

1. With the calculator off, hold down the [ON] key and press [X] (the multiply key)..
2. Release the [ON] key, then release the [X] key. This initiates a complete test of the calculator’s electronic circuitry. If everything is working correctly, within about 25 seconds (during which the word RUNNING the display should show –8,8,8,8,8,8,8,8,8,8, and all of the status indicators (except the * battery power indicator) should turn on. If the display shows Error 9, goes blank, or otherwise does not show the proper result, the calculator requires service.

Tests of the calculator’s electronics are also performed if the [+] key or the [divide] key is held down when [ON] is released. These tests are included in the calculator to be used in verifying that it is operating properly during manufacturing and service.
