Before You Get to the Track

drivers and their possible frequencies that were 
known when it was manufactured.

Before you leave for the track, check the 
Internet to see if there are any frequency 
updates available for your race. You can save 
time at the track by setting up as much as 
possible before you leave.

When You Get to the Track

When you arrive at the race, get a list of the 
frequencies in use that race day. These are 
normally available for sale on the way into the 
facility. This list will show the actual frequency 
being used by each driver that day, as well as 
some other useful frequency information.

Then, follow the steps in the following sections 
to adjust the scanner settings.
