CHANNEL ACTIVITY BARS
Your scanner has 20 channel activity indicators (bars)
which show the activity taking place on a trunked sys-
tem. You can see how many frequencies are being
used and generally monitor how much communication
traffic is occurring.
Each frequency you store in a trunking bank has a cor-
responding activity bar. However, since there are only
20 bars, but you can store up to 30 frequencies, some
bars might indicate more than one frequency if the
trunked system you are scanning has more than 20
channels.
• The bar that remains on steadily even when there
are no current transmissions represents the fre-
quency being used as the data channel.
• The bar that flashes when an ID appears repre-
sents the frequency being used by the radio to
transmit what you are currently hearing.
• If a bar turns on but you do not hear a conversa-
tion, the channel is probably being used for a tele-
phone interconnect call or a private call, or the bar
might be a locked-out ID. Your scanner does not
monitor these types of calls.
• If the scanner is holding on an ID which is not
active, the other activity bars turn on and off as
other groups use the system.
