The Recall Setup command allows the user or host to recall the Setup parameters that were in
effect when the Save Setup command was last executed.
When the Recall Setup command is issued, the Setup parameters in effect at the time are
overwritten by the most recently saved Setup parameters. This allows a program to temporarily
modify the TCS Setup parameters, then restore the Setup parameters to their original values.
The effects of the Recall Setup command are summarized in Table 4-l.

When previously saved Setup parameter values are recalled from nonvolatile Setup memory by
the Recall Setup command, the TCS verifies the checksum of the parameter data. If the checksum
is in error, the nonvolatile memory has malfunctioned. The Setup parameter values are not
changed and an error is reported in the Operational Status Window of the Setup Screen.
