• Tune to a powerful local FM radio station, then write down the radio station number.
• Tune to a powerful local AM radio station, then write down the radio station number.

1. Enter the reception level indication mode in the self-diagnostic function. The AM/FM antenna amplifier is on and the character (A) is not displayed in the audio display.
