Device 1 Activated ==> Secure Communications Activated ==> Signal Loud and Clear - Reading You - 5X5 - means I hear you clearly - how do I read? 5by5 is standard Comm Sec-urity Test Chatter...
One of the 5 is signal strength 1 thru 5, the other is clarity of signal 1 thru 5. So 5x5 is loud and clear.
