Clock
The PTC-960XRF has a built-in clock that keeps
track of the date (month, day, year, and day of
the week) and the time (hours, minutes, seconds,
and tenths of seconds). The clock operates con-
tinuously. How the clock is used depends on your
application program. For example, the PTC-
960XRF can use the clock to show the date and
time on its display or to direct a printer to place
a time stamp on a report.

Communication
The PTC-960XRF is capable of communicating
with a host computer through its internal radio,
through an optional communication cradle, or by
being connected directly via a cable. See the man-
ual or instructions provided by your organization
for the proper communication procedure for your
application.

Display contrast
You may be able to adjust the PTC’s display con-
trast, depending on the display installed on your
PTC and the operating system your PTC uses.
If your PTC’s operating system is MS-DOS, you
can increase or decrease the contrast in steps by
first pressing the FUNC key and then pressing
the BKSP (backspace) key.
If your PTC’s operating system is TCAL, contrast
adjustment may or may not be available to you,
depending on your organization’s application
program. See the instructions provided by your
organization for the correct procedure.
