HP 17bII manual Confirming Calculator Operation Self-Test

Confirming Calculator Operation:

Self-Test

If the display can be turned on, but it appears that the calculator is not operating properly, you can do a diagnostic self-test. The self-test runs continuously, repeating until you halt it.

To run the self-test:

1.Turn the calculator on.

2.If you have the optional infrared printer, turn it on. Certain diagnostic information is printed during the test.

3.If possible, return to the MAIN menu (press @A).

4.To start the self-test, hold down Cwhile you press the fifth menu key from the left. Once the self-test has begun, do not press any keys until you are ready to halt the test.

5.During the test, the calculator beeps periodically and displays various patterns and characters. Watch for one of two messages that are displayed before the test automatically repeats:

„If the calculator passes the self-test, the calculator displays



„If the calculator displays  followed by a five-digit number, the calculator requires service.

6.To halt the self-test, hold down Cwhile you press the third menu key from the left. The calculator displays  . If you press any other key instead, the test halts and the calculator displays

a  message. This results from an incorrect key being pressed, and does not mean that the calculator requires service.

7.If the calculator failed the self-test, repeat steps 4 through 6 to verify the results. If you do not have a printer, write down the messages that are displayed in step 5.
