I was programming CP 110's using ver 2.00 software. 2 of the radios now show alternating red/yellow led indications and attempts to read have the following message: "Warning radios memory is corrupted. Perform factory reset option to correct this problem." How do I do this or does it mean a trip back to M.
Thanks to all.

I finally found it. Reset is done by holding down ptt and both side buttons until the second series of beeps is heard. I had to do the reset twice before I got the radio programmed. The program still requires multiple tries to get it to read or write.
