Appendix D Continuous Memory (HP-<strong>38C</strong> only) When you turn off your calculator, the following information is retained: • Contents of the financial registers and the storage registers. • All programs that are loaded into the calculator. Numbers in the stack and LAST X register are not preserved when you turn off the calculator. Regardless of where you stopped in a program, the calculator returns to line 00 (top of program memory) when you turn it on again . Executing the self-check does not clear program memory, storage registers, or financial registers. Continuous Memory requires that the batteries be kept in the calculator. If the low power indicator appears in the display, turn your calculator off immediately and connect it to an ac outlet or insert a new battery pack. Continuous Memory requires that batteries be replaced as quickly as possible. Normally you have a minimum of 5 seconds to change the batteries . Leaving the batteries out of the calculator fo r extended periods, or allowing the batteries to discharge completely will result in loss of the info rmation in Continuous Memory. If you drop or traumatize your calculator, or if power to the Continuous Memory is interrupted whether the calculator is off or on, the contents of program memory and the data storage registers may be lost. If this occurs, when the calculator is then turned on, the display will show Pr Error. To restore the display, ensure that the battery is charged, or connect the ac adapter/recharger, and press any key. CAUTION Switching off the HP-<strong>38C</strong> during execution of either a program or a function may clear or alter instructions in program memory and data in the financial or storage registers. 140
