Complement Status. The Complement mode is 0 (Unsigned), 1
(1’s), or 2 (2’s).
Flag Status. The display portion for flag status shows four places
held by zeros or ones. The flags are numbered from the right from
zero to three; a place occupied by 1 represents a set flag. For
example, consider the following flag portions of [STATUS] displays:
#3210 #3210
-0100 Flag 2 set. -1101 Flags 0, 2, and 3 set.
Special Displays
Annunciators
The HP-16C display contains six annunciators that indicate the
status of the calculator for various operations. The meaning and
use of these annunciators are discussed on the following pages:
* Low-power indication, page 38.
fandg Prefixes for alternate functions, page 17.
C Flag 4 (carry) set, page 39.
G Flag 5 (out-of-range) set, page 40.
PRGM Program mode, page 72.
Error Display
If you attempt an improper operation—such as specifying a word
size larger than 64—an error message will appear. For a complete
listing of error messages and their causes, refer to appendix A.
To clear the Error display and restore the calculator to its prior
condition, press any key. You can then resume normal operation.
Low-Power Indication
A flashing asterisk in the lower left-hand corner of the display
indicates low battery power. At this point, however, you still have
operating time remaining: at least 15 minutes if you run a program
continuously, or at least an hour if you do calculations manually.
(Certain batteries provide more time.) Refer to appendix C (page
102) for information on replacing the batteries.
