Processing Calls
CAUTION: SAVING
SETTINGS FOR PCS
OPERATION
To use SAVE/RECALL registers, you must use the same hardware configuration present
at the time the register is created. If you save instrument settings when a PCS Interface is
connected to the Test Set, the Test Set expects to detect the presence of the interface when
the register is recalled. If the PCS Interface is not connected to the Test Set when the reg-
ister is recalled, or the interface is turned off, a non-recoverable firmware error occurs. If
you encounter this error, the Test Set must be turned off, and the PCS Interface must be
connected and turned on, before the Test Set can power up normally and function correctly.
