cadex

I do have a few fleets of mainly XPR3500 and XPR7550 radios so I was wondering if investing in one of those Cadex 7x00 units still makes sense in terms of the batteries those radios use nowadays and IMPRES being almost universally being used on most batteries and chargers, although some radios...

I have a recently acquired a C7200 to replace my ancient C4000. Unfortunately this thing requires a password. Does anyone know how to get past this? The owners manual says that I need to call Cadex for a reset request. As this does not connect the internet, it must be some sort of key sequence.
