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
Your calculator has a TWO WAY POWER system that combines a solar cell with a button
battery (LR44). Unlike solar cell-only calculators that operate only when light is present, a
TWO WAY POWER system calculator keeps on operating even in the dark. (Of course, you
will need enough light to be able to read the display contents.)
A
Replacing the Battery
Dim display characters, especially when using the calculator where lighting is dim, or slow
display response when you turn on the calculator indicates that button battery power is low.
Replace the battery whenever you notice these symptoms. You should also regularly replace
the battery at least once every three years, even if the calculator is operating normally.
Important!
Removing the button battery from the calculator causes independent memory contents and
values assigned to variables to be cleared.
