Sound Quality Diagnosis
Diagnostics CD 07AAZ-SDBA100
Use the following tests to check sound quality.
NOTE: Before beginning the following tests, write down
the client’s bass, treble, fader and balance settings, and
then set them to their center positions for testing.
Do this test to confirm proper channel routing.
1. Insert the diagnostics CD (T/N: 07AAZ-SDBA100) into the navigation unit or audio unit.
2. Play track No. 1 (left, both, right channel ID) at a normal, or slightly higher than normal, volume
level.
3. The voice should be audible only from the channel or channels when indicated.
 If the channel ID is correct for each side, go to the phase test.
 If the channel ID is not correct, check for; – Shorted speaker wire
– Faulty amplifier (Type S model)
– Faulty navigation unit
– Faulty audio unit Diagnostics CD 07AAZ-SDBA100
Do this test to confirm proper speaker phasing.
1. Insert the diagnostics CD (T/N: 07AAZ-SDBA100) into the navigation unit or audio 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 wires
– Faulty amplifier (Type S model)
– Faulty navigation unit
– Faulty audio unit
