Stacks
This calculator uses memory areas, called "stacks", to temporarily store
values (numeric stack) and commands (command stack) according to their
precedence during calculations. The numeric stack has 10 levels and the
command stack has 24 levels. A stack error (Stk ERROR) occurs
whenever you try to perform a calculation that is so complex that the
capacity of a stack is exceeded.

Dim figures on the display off 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.
