Backup battery
!
Do not store a PTC-960L for over
two months without charging the
nickel-cadmium battery pack or
replacing the alkaline battery. Any
data or programs loaded into the
PTC’s memory will be lost.
The PTC-960L’s built-in backup battery provides
enough power to protect data stored in the PTC’s
memory when the battery is being replaced or if it
runs out of power. The backup battery system
provides approximately 20 minutes of protection
when the main battery is removed.
Beeper
The PTC’s beeper is used by the PTC and your
application program to warn you of problems or to
prompt you to take an action. For example, if your
application program has temporarily turned off a key,
the PTC will beep if you press that key.
Depending on your organization’s application
software, you may be able to control the beeper’s
volume. See the manual or information provided by
your organization.
Clock
The PTC-960L 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 continuously. How the
clock is used depends on your application program.
For example, the PTC-960L can use the clock to show
the date and time on its screen or to direct a printer
to place a time stamp on a report.
Communication
The PTC-960L is capable of communicating with a
host computer through an optional communication
cradle or by being connected directly with a cable. See
the manual or instructions provided by your
organization for the proper communication procedure
for your application.
