k Before assuming malfunction of the

calculator...

Perform the following steps whenever an error occurs

during a calculation or when calculation results are not

what you expected. If one step does not correct the

problem, move on to the next step.

Note that you should make separate copies of important

data before performing these steps.

1. Check the calculation expression to make sure that it

does not contain any errors.

2. Make sure that you are using the correct mode for the

type of calculation you are trying to perform.

3. If the above steps do not correct your problem, press

the O key. This will cause the calculator to perform a

routine that checks whether calculation functions are

operating correctly. If the calculator discovers any

abnormality, it automatically initializes the calculation

mode and clears memory contents. For details about

initialized settings, see  Initializing the Calculator  on

page E 3.

4. Initialize all modes and settings by performing the

following operation:

(1) O19(CLR)

(2)  All:EXE  (fc), then E.

(3) E(Yes)
