Q:

48
will flash when I turn it on. Is this normal?
A:
This is normal for the HP 48.
Q:
I’m not sure whether the calculator is malfunctioning or if I’m
doing something incorrectly. How can I verify that the calculator is
operating properly?
A:
See “Testing Calculator Operation” on page A-9.
Q:
The
(i*>)
annunciator stays on even when the calculator is turned
off. Is anything wrong?
A:
This indicates a low-battery condition in the calculator or a RAM
card, or an alarm that is past due. To determine what is causing
the (ci) annunciator to stay on, turn the calculator off and then on.
A message in the display will identify the problem. See “When to
Replace Batteries” on page A-4 or “Responding to Alarms” on page
26-4.

How can I determine how much memory is left in the calculator?
A:
Press fi^fMEMORYl MEM . The number of bytes of available
memory will appear at the lower right corner of the display.
For example, an empty memory for the HP 48GX should show
approximately 127000 bytes of internal RAM (with no RAM cards
installed).
