Autodiscrimination between bar codes
See Appendix C for a list of
the bar-code types your PTC
is programmed to read. Your PTC-921 DOS’s application program can read
and automatically discriminate between up to six
different bar-code types.
Automatic off
Refer to the RAMSaver Application
Development Manual for program-
ming instructions.
To conserve battery power, the PTC-921 DOS auto-
matically turns itself off after approximately 1 minute
of inactivity. The exact length of time depends on how
your application program has been configured.
Automatic return at on
When you turn off the PTC-921 DOS (or when the
PTC turns itself off), it remembers where it was in the
application. Then when you turn the PTC back on, it
returns to that same point in the application. You do
not need to review what you have done or perform
any other start-up function to find your place.
Backup system
! Do not store the PTC for over
two months without charging or
replacing the battery pack. Both
the main battery and the super
capacitor will drain, and any data
or programs in the PTC’s memory
will be lost.
The PTC’s super capacitor provides enough power to
protect data stored in the PTC’s memory when the
battery pack is being replaced or if it runs out of
power. This backup system provides approximately
20 minutes of protection when the battery pack is
removed.
