About Continuous Memory (HP-38C only)
If you purchased an HP-38C instead of an HP-38E, your calculator contains Continuous
Memory-one of the most advanced memory systems available in a financial
calculator. Even when the calculator is turned off, the financial registers and the
storage registers save information such as cash flows, amortization data, or intermediate
answers for later updating or calculations. Continuous Memory also allows
you to save any programs you frequently find useful, whether short, like a checkbook
balancer, or longer, like a bond calculation, for as long as you want.
And , continuous memory helps save battery life! Much of the time a calculator is
switched on is spent holding information, waiting for the next computation. Continuous
Memory eliminates much of this unneeded battery usage by allowing you to switch
off the calculator when you have a prolonged pause or interruption between
calculations.
Note: Unless otherwise indicated, "HP-38E" is used throughout this handbook to
refer to both the HP-38E and the HP-38C.
