(Explain to customer that SEEK sometimes does not stop depending on signal reception condition.) NOTE: Signals tend to reach longer distances in the night. It is noticeable in AM signals, several audio functions may stop due to foreign broadcasting station or noise. Though the audio system restrains sensitivity of SEEK and SCAN functions in the night, the audio system may select other than desired broadcasting station when signals are considerably strong. This function is linked to the parking light. When the parking light or headlight is turned on, SEEK and SCAN may not function for weak signals.
