Why are Channel Activity Indicators flashing but no sound on my Uniden BC785D Scanner?
If Channel Activity Indicators are flashing but no sound is heard on your Uniden scanner, it could be due to these reasons: First, it may be a telephone interconnect call, which are intentionally blocked by your scanner. Second, the ID on your display is not active.
Why don't I see APCO P25 CARD message on my Uniden Scanner?
