Note: Your application program may turn off
certain keys at times during the program to
prevent you from accidentally erasing data or
ending an operation. The PTC beeps when you
press a key the application has turned off.
ENTER/YES key
How you use the ENTER/YES key depends on
your organization’s application. Usually you
press this key to tell the application that you
have finished typing data, have finished an op-
eration, or want the PTC to begin an operation,
such as sending data to the host computer.
ON/OFF key
Pressing this key will turn the PTC on or off.
SHIFT key
On the 45-key keyboard, the SHIFT key acti-
vates only the function keys labeled on the over-
lay. The numeric keys are always available.
On 24- and 35-key keyboards, the SHIFT key
shifts between the numeric and alphabetic key-
board and also activates some of the function
keys your application uses. These keys are la-
beled on an overlay that slips over the keyboard.

Keyboard overlay
The keyboard overlay is a small sheet of plastic
cut out to fit over the PTC-960XRF’s keyboard.
Labels for the special function keys used by your
organization’s application program are printed
on the overlay.
