MONITORING IDS
You can use your scanner’s display to monitor the frequencies in a trunked system for activity. You cannot hear conversations in this mode, but this is an excellent way to determine which talk groups are the most active.
To set the scanner to monitor IDs, hold down SEARCH until the scanner beeps twice. SEARCH flashes, and all talk group IDs appear in succession. To stop monitoring IDs, press SEARCH again.
Note: When you monitor IDs, locked- out IDs also appear.
CHANNEL ACTIVITY INDICATORS
Your scanner has 20 channel activity indicators (bars). The bars show that transmissions are being received on a trunked system.
•The bar that flashes when an ID appears represents the frequency being used by the radio you are currently hearing.
•If a bar turns on but you do not hear a conversation, the channel is probably being used for a tele- phone interconnect call or a pri- vate call, or the indicator might be a
•If the scanner is holding on an ID which is not active, the other bars turn on and off as other groups use the system
A bar appears for each frequency you store in a trunking bank.
You can use the bars to tell how many frequencies are being used and gen- erally monitor how much communica- tion traffic is occurring on a trunked system.
•A bar that remains on steadily even when there are no current transmissions represents the fre- quency being used as the data channel.
SCAN LISTS
When you program trunked frequen- cies into a bank (see “Programming Trunked Frequencies” on Page 32), your scanner sets up 5 scan lists into which you can store your favorite IDs. Each list can contain up to 10 IDs, so you can store a total of 50 IDs for each trunk scanning bank (1000 IDs if you use all banks as trunking banks).
