[1] If the PSO receiver frequency is changed the PSO receiver status will automatically revert to a restrictive state and
will the text 1CAL (or 2CAL) on its 4-character display, the Display module will also indicate that receiver calibration is
required on its system status screen and Diagnostic view.
[2] If the island frequency is changed the Island status will automatically to a restrictive state and the module will
show the text ICAL on its 4-character display, the Display module will also indicate that receiver calibration is required
on its system status screen and Diagnostic view.
[3] In general, the PSO and Island calibration is not required when the software is updated. However, in some cases
due to the nature of the change, it may be necessary to force a recalibration. The module will automatically detect
whether calibration is required and display diagnostic data as per notes [1] and [2].
[4] Calibration may be required for a specific software update as detailed in the Product Release Bulletin (PRN)
associated with the new software.
[5] The PSO Module will detect that it is not in the slot or chassis that it was calibrated for and automatically detect
calibration is required and display diagnostic data as per notes [1] and [2].
[6] When the programming is set to default or a new MCF is loaded, the PSO and island frequencies will revert to Not
Set, this will cause the PSO module to report that calibration is required. If the PSO or Island frequency is then set
and the value is the same as that which was previously programmed into the module for this receiver or island, then it
will stop reporting that calibration is required. It is up to the user to remember to calibrate it. If the new frequency is
different from the old one, the module will report calibration is required.
