NOTE: To enter the speaker walk-around test or ACM Self-Diagnostic Mode, the ACM must be ON and in radio tuner mode (AM/FM). The ACM Self-Diagnostic Mode can only be entered while in the speaker walk-around test.

1. To enter the speaker walk-around test, simultaneously press the ACM Preset Buttons 3 and 6.
2. The speaker walk-around test stops at each speaker and applies a different tone to each speaker for about 1-2 seconds. Each speaker is tested and displayed on the ACM in the following sequence: RF, LF, LR, RR, Subwoofer I, Subwoofer II.
3. The speaker walk-around test automatically continues and tests:
^ for speaker short. If a short is present, SPKR SHORT will be displayed.
^ for CD/DJ. The ACM display will show NO DJ if not present.

The speaker walk-around test will end and the ACM will return to its previous setting.

To enter the following ACM self-diagnostic modes, press the preset button desired while in the speaker walk-around test. This will abort the speaker walk-around test and start the selected test.
