Phase Test

Do this test to confirm proper speaker phasing.

1. Insert the audio diagnostic CD (T/N 07AAZ-SDBA100) into the audio unit or the audio-navigation unit.
2. Play track No. 2 (phase) at a normal, or slightly higher than normal, volume level.
3. The voice should sound centered and focused when it is in-phase.
4. The voice should sound diffused, and have less bass when it is out of phase.
   • If the voice changes from in-phase to out of phase as indicated by the prompt, the phasing is correct. Go to ELECTRICAL NOISE TEST .
   • If the voice always sounds out of phase, phasing is not correct. Check for:
     • Crossed speaker wire
     • Faulty stereo amplifier
     • Faulty audio unit or audio-navigation unit
