Basic financial functionality is addressable after depression of the Set Up key followed by a depression of
the ♦ Subtotal key. Enabling this feature changes the operation of Memory I and Memory II to the
alternative functionality identified above and described below:
The keys (Amount, Interest, # of Months and Payment) are designed to provide the user the ability to
solve for Amount, # of Months, or Payment provided input has been made for Interest and two of the
three other variables. Interest must be entered. User may not solve for Interest. The amounts stored
are not cleared once the missing variable has been computed. This enables the user to use
some of the same variables to solve for different values. Compute followed by the C/CE key,
clears all variables. Entering a new amount and pressing any of the four keys identified
here, replaces the amount currently stored with the new amount.
Example:
Loan Amount $100,000, Interest 6.5%, Term 15 Years. Compute Payment
