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 copies of important copies of important data before performing
these steps.
1
Check the calculation expression to make sure it does not include 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 restore normal operation, press the
p
key. The calculator will perform
a self-check of its status as it starts up. If the calculator discovers a problem, it will return its
calculation mode and setup to their initial defaults, and clear all data currently in memory.

Power Requirements
A
Replacing the Battery
Dim figures on the display of the calculator indicate that battery power is low. Continued
use of the calculator when the battery is low can result in improper operation. Replace the
battery as soon as possible when display figures become dim. Even if the calculator is
operating normally, replace the battery at least once every three years.
Important!
Removing the battery will cause all of the calculator’s memory contents to be deleted.
