Data keys are the letter and number keys, A-Z and 0-9. You use
them to type data into the PTC. Function keys include the
F1-F5, CLEAR, ENTER/YES, and SEND keys. These keys may
have different labels on your PTC. They are used to perform a
special procedure or function. For example, your program may
use the SEND function key to transmit the PTC’s data to the
host computer.
ENTER/YES key
How you use the ENTER/YES key depends on your
organization’s data collection program. Usually you press this
key to tell the program that you have finished typing data,
have finished an operation, or want the PTC to begin an
operation, such as sending data to the host computer.
ON/OFF key
Pressing this key turns the PTC on or off.
SHIFT key
On a 50-key keyboard, the SHIFT key activates only the
function keys labeled on an overlay that slips over the
keyboard. The numeric keys are always available.
On a 40-key or 24-key keyboard, the SHIFT key shifts between
the numeric and alphabetic keyboard and also activates some
of the function keys your program uses. These keys are labeled
on the overlay.
Note: Your data collection program may turn off certain keys
at times during the program to prevent you from accidently
erasing data or ending an operation. The PTC beeps when you
press a key the program has turned off.
