Note: To see the bank currently in use for about 5 seconds, press DATA while in the trunk tracking mode.

3.To return to conventional scan- ning, press TRUNK again.

Hint: While scanning, you will not know exactly whom the IDs are as- signed to until you listen awhile or until you locate ID lists in frequency guides or on internet sites such as www.trunkscanner.com. Within a few minutes, you can usually figure out if what you are listening to is a police, fire, or emergency medical 2-way ra- dio user. Other IDs might take some time, but determining whom each ID represents is half the fun of trunk tracking!

Monitoring an Active ID

When the scanner stops on a trans- mission, you can hold the scanner on that transmission.

1.Press HOLD. HOLD appears and the scanner stays on the current ID.

2.If you want to listen to a different ID, use the number keys to enter

28

the ID you want to hold. LIST 1 appears

3.Press HOLD again. HOLD flashes and the scanner monitors that ID.

4.When you want to stop the hold and resume searching for a data channel so you can continue trunk tracking, press SEARCH.

Note: You can also follow these steps to hold on an ID while scanning a scan list. See “Scan Lists” on Page 31.

Locking Out IDs

As with conventional scanning, it is possible to lock out unwanted traffic. This is particularly important in trunk- ed systems because signals you can- not listen to (such as water meters, door alarms, traffic signals, and en- crypted signals) are assigned IDs just like other users. You can have up to 100 IDs locked out at one time.

Note: If you lock out an ID while searching, it is also locked out of the scan list(s). See “Scan Lists” on Page 31.
