A-320 Pws/windshear

HI Guys

Been trying my best to understand it, but without any luck . As per the book PWS (predictive windshear) scans on the 320 below 2300ft and ATC ON/AUTO, 1 engine running etc etc. But it gives warnings, cautions only below 1500ft.
My question is what happens if the A/C is below 2300ft and above 1500ft and there is windshear ahead??? Will the PWS still show any thing on the ND??
Secondly, what if the A/C is in actual windshear below 2300ft and above 1500ft?? Will there be any alerts,warnings,cautions on the ND??

There's one diagram as per which below 2300ft and above 1500ft, Windshear mode active, there will be no ALERTS/DISPLAYS.
