Question: How do I get On-air Programming to work with my computer?
Answer: The steps in the manual are incorrect; On-air programming allows you to program your scanner by tuning to a particular frequency
provided by the racetrack. It does not use a computer. The correct steps for doing this are given below:
1. Turn off the scanner.
2. While pressing ENT and 8, turn on the scanner. On Air and PGM appear and the scanner automatically receives 154.600 MHz in FM
mode. Then On Air and the frequency alternate.
3. If you do not want to use 154.600 MHz to receive programming, press PGM. PGM flashes. Then, use the number keys to enter the
frequency you want to receive and press ENT.
4. To change the frequency back to the default (154.600 MHz), hold down ENT then press CL.
Note: You cannot use an AM frequency during on-air programming. Do not enter a frequency between 108.000 and 136.9875 MHz.
5. When the scanner successfully receives all data, End and FiniSh appear. If the scanner received an error while receiving data, End and
d-Err appear. If the scanner received a checksum error while receiving data, C-Err and a number appear. The number shown next to C-
Err indicates the packet number where the error occurred.
