Good Morning,
I recently purchased an XPR 5550 used & a new PMLN7131 remote control head.
I programmed the radio without any issues dragging zones from an XPR 4550 codeplug file to the 5550. Radio works great with the control head attached. However the receive audio will pop and crack, on both analog & digital. The firmware on the 5550 is R02.50.05 which is the latest, however in the manual for the control head I noticed that if one of the red LEDs is flashing it indicates that there is a firmware mismatch between the control head & the radio.
Thoughts?
