Reception Level Indication Mode

This diagnostic screen checks the audio unit's reception level, and is displayed in decibels (dB).

This level then can be used in the diagnosis of audio unit reception quality.

Preparation: 

• Park the vehicle outdoors where you get good radio reception.
• 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 (A-SEL or TP is not displayed in the audio-HVAC display).
2. Tune to the FM radio station you wrote down in Preparation using the TUNING knob, and note the decibel level of that station when you release the button.
