Hi all
I have a Motorola mc2100 and when switched on displays ICP ver xxxxxx
What is this and how can I get a codeplug into radio.I have mc2100 RSS and wookie but can't get any to clear this message
Any help is appreciated
Thanks in advance

Just an update it turns out these mc2100 radios I have were programmed with special ambulance RSS never heard of this before but that's what I have been told so I will have to reflash them with mc2100 upgrade RSS
