Why are the channel activity bars flashing on my Radio Shack PRO-94 but there is no sound?

If the channel activity bars are flashing but no sound is heard, it may be because: * The transmission might be a private or telephone interconnect call, which the scanner does not scan. Try scanning for another transmission. * The ID shown is not active. Wait for the ID to become active, or scan another transmission.
