Our experience shows that many customers have similar questions about our products, so we have provided the following section, "Answers to Common Questions." If you don't find an answer to your question, contact the Calculator Support Department listed on page A–8.

Answers to Common Questions

Q: How can I determine if the calculator is operating properly?

A: Refer to page A–5, which describes the diagnostic self–test.

Q:My numbers contain commas instead of periods as decimal points. How do I restore the periods?

A: Use the 85(5) function (page 1–23).

Q: How do l change the number of decimal places in the display?

A:Use the 8menu (page 1–21).

Q:How do I clear all or portions of memory?

A: displays the CLEAR menu, which allows you to clear x (the number in the X-register), all direct variables, all of memory, all statistical data, all stack levels and all indirect variables

Q: What does an "E" in a number (for example, ) mean?
