Error Check 90 Receiver Jam

I have a vista 20p with the alpha keypad w/out mike.
today, all of a sudden, im getting the message and a intermittent beep that says check 90 receiver jam.
Any ideas?

Unless this is a high security install, change the setting on *22 to 0. That jam detection feature can be set off by things like too many cordless phones in the receiver location.
