HP HP-16C User Manual

Section 1: Getting Started 17
Notice that when you press the or Ok
(9] prefix key, an f or g annunciator f
appears and remains in the display
until another key is pressed.
Clearing Prefix Keys
A prefix key is any key that must be followed by one or more
additional keys to complete the key sequence for a function. There
is a list of all prefix keys in appendix B.
When any prefix key (such as or (f]) has been pressed,
pressing CLEAR will clear that prefix key, leaving the
calculator ready for a new keystroke. If you have mistakenly
pressed [f]instead of (9] or vice-versa, you can correct it merely by
pressing the other key.
The “CLEAR"’ Keys
The ““CLEAR’ operations are listed below. Clearing a register
means to replace its contents with zero.
Clearing Sequence Effect
(fJCLEAR [PRGM
In Run mode: Repositions program memory to line 000.
In Program mode: Clears entire program memory.
(f]JCLEAR Clears all data storage registers.
(f)JCLEAR Cancels any prefix from a partially
entered key sequence.
Display Clearing: [CLx]and
The HP-16C has two types of display clearing operations:
(clear X) and (back space).
In Run mode:
° clears the display to zero.
° deletes only the last digit in the display if digit entry has
not been terminated. ([ENTER] and most other functions
terminate digit entry so that the next digit keyed in becomes
part of a new number.) You can then key in (a) new digit(s) to
replace the one(s) deleted. If digit entry has been terminated,
then acts like [CLx].
