While a radio is performing a scan of conven- tional radio channels, it is possible to miss emer- gency voice messages on the channels being scanned. This could happen because there does not happen to be activity on the emergency channel at the time it is scanned. The problem with this is that a radio user will not know that there is an emer- gency situation, and thus will not be able to assist in dealing with the emergency. With the characteristic that voice calls on a radio system tend to be short, it is possible that many voice calls with emergency information could be missed because the radio is scanning elsewhere or is locked on another channel.
