So I bit the bullet and got the system. While trying to configure delays via keychain remote, PC would not 'see' it via USB. Called tech. Spent 67 min on phone with (young) rep who recommended I try my MacBook. Keychain remote locked up my macbook and I lost work. Bad. Very Bad.
Base station would also not register via cell so plugged it into ATT hard line. Still would not register. Removed cone housing and removed/reinstalled sim card. Still no joy. Reassembly requires aligning pin which was not recognized by tech and another 5 min of assembly frustration.
