4. press number 1 button until it reaches the correct number for the first digit.
5. press number 2 button until it reaches the correct number for the second digit.
6. press number 3 button until it reaches the correct number for the 3rd digit.
7. If radio has scan button hold it down. If radio doesn't you can hold down am/fm button or power button. radio should come back up with word sec again then shut off. You may need to manually turn it off (I can't quite remember). Turn radio off then back on.
