HP 15c Collector's Edition User Manual

62 Section 5: The Display and Continuous Memory
Low-Power Indication
When an asterisk, which indicates low battery
power, appears in the lower left-hand side of
the display, there is no reason to panic. You still
have plenty of time remaining before
Continuous Memory is lost, but the batteries
should be replaced as soon as possible. The
calculator will switch to a slower, low-power
mode to conserve battery power at this point.
As the remaining power drops, the calculator
may turn off on its own during calculations.
Refer to Appendix F (page 259) for information
on replacing the batteries.
Continuous Memory
Status
The Continuous Memory feature of the HP 15c retains the following in
the calculator, even when the display is turned off:
 All numeric data stored in the calculator.
 All programs stored in the calculator.
 Position of the calculator in program memory.
 Display mode and setting.
 Trigonometric mode (Degrees, Radians, or Grads).
 Any pending subroutine returns.
 Flag settings (except flag 9, which clears when the display is
manually turned off).
 User mode setting.
 Complex mode setting.
When the HP 15c is turned on, it always “wakes up” in Run mode.
If the calculator is turned off, Continuous Memory will be preserved
unless the batteries are removed. Refer to Appendix F for instructions on
changing batteries.
