Backup battery
All models of the PTC-860 have a built-in backup battery. The
backup battery provides enough power to protect data stored in
the PTC’s memory when the main batteries are being changed
or if they run out of power.
A switch inside the PTC, accessible through the battery door,
lets you turn on the backup battery. The PTC-860 is shipped
from the factory with this switch turned off to conserve the
backup battery power.
Note: Once you turn on the backup battery by pushing down
on the backup battery switch, do not attempt to reraise the
switch. It is meant to stay down permanently.
If your PTC shows a “Backup Battery Fault” message when
you turn on the PTC, either turn on the backup battery or
have the backup battery replaced. (Do not attempt to replace
the backup battery yourself; contact your Telxon service
representative for assistance!)
CAUTION! Do not store a PTC-860 for over two months
without charging the battery pack or replacing the alkaline
batteries. Otherwise, both the primary batteries and the
backup battery will drain, and any data and programs
loaded in the PTC’s memory will be lost.

Bar-code reader (optional)
The PTC-860 unit (not including the PTC-860ES and
PTC-860NI units) may have an optional bar-code reader
that plugs into the wand port on the side of the unit. If your
PTC-860 unit was ordered with a pencil-wand bar-code reader,
it has a holder for the reader attached to its side.
Bar-code readers are available for the PTC-860ES and
PTC-860NI but must be connected to the units through the
25-pin connector.
