USING THE PRO-74 AT THE RACES

The PRO-74 is specially designed to help you listen to communications
at auto races. Drivers and their pit crews and corner watchers, pace
car drivers, security officers, emergency personnel, track officials, and
representatives of governing organizations such as NASCAR, SCCA,
and NHRA all use radios to communicate with each other during a
race. You might also hear transmissions from the news media and re-
porters, local police departments, and paramedics and doctors at the
local hospital. You can even listen to broadcasts by parking lot employ-
ees at the track, so you can find the best possible parking place when
you arrive.

The scanner’s quick-track memory lets you store a car number and fre-
quency in each of the scanner’s channels, associate one or more fre-
quencies stored in channels with a car number, and recall any
frequencies associated with that car number by entering the number.
You can store one car number by itself, one car number and frequency,
or one frequency by itself in each channel (for up to 100 car numbers
and frequencies).

For example, if you want to listen to communications between the driv-
er of car number 24 and that driver’s pit crew, find all the frequencies
used by the driver’s team by using the steps in “Searching the Service
Banks” on Page 25, using the supplied frequency guide, “Searching
from a Selected Frequency” on Page 26, or using frequencies you al-
ready know, then store a car number and the frequencies associated
with that car number in the scanner’s channels. Then, you can display
the car number as you scan those frequencies by using the information
in “Scanning by Car Number” on Page 33.

STORING A CAR NUMBER AND FREQUENCY

You can store a car number and frequency in each of the scanner’s
channels, and you can recall any frequencies associated with the car
number by entering the number. You can store one car number in each
channel (for up to 100 car numbers).

Note: After you store a car number and a frequency, you can store ad-
ditional frequencies then associate those frequencies with the same
car number. See “Adding Frequencies to a Car Number” on Page 32.
