Ô NOTES Ô 
This scanner uses the 
same memory between 
conventional channel 
mode and car number 
operation. If you remove
 the conventional 
channel’s lockout which 
also locks the channel of
 a programmed car 
number, the scanner 
removes the lockout 
from the car number 
operation.

ON-AIR 
PROGRAMMING
You can also program your 
scanner by receiving data 
transmitted on a frequency your 
scanner can receive (called on-air 
programming).
You can use on-air programming 
to store the following data into the 
scanner:
 Channel number (from 000 to 
949)
 Frequency (any frequency the 
scanner can receive)
 Car number (from 0 to 999, 
including 00, 000, 01, and 
001)
 Channel text tag
 Channel lockout setting (ON 
or OFF)
 Channel delay setting (ON or 
OFF)
 CTCSS code (67 Hz – 250.3 
Hz)
 CTCSS setting (ON or OFF)
Ô NOTES Ô 
 The scanner receives
 only the data shown 
above during on-air 
programming.
 On air programming 
data is normally 
transmitted at the 
race track during 
races.

Invalid Freq. orInvalid Ch appears if 
the scanner receives a channel number 
equal to 0 or 
frequency data which
 is out of the range of frequencies the 
scanner can receive.

Checksum Error 
appears if the 
scanner receives a 
checksum error.

Birdie Frequencies
Every scanner has birdie 
frequencies. Birdies are signals 
created inside the scanner’s 
receiver. These operating 
frequencies might interfere with 
transmission on the same 
frequencies. If you program one of 
these frequencies, you hear only 
noise on that frequency. If the 
interference is not severe, you 
might be able to turn 
SQ clockwise 
to cut out the birdie. This 
scanner’s birdie frequencies (in 
MHz) are:
162.400 162.425 162.450
162.475162.500162.525
