DM100i, CDX6, and M100 AM/FM Single Compact Disk Audio Unit

NOTE:
^ The audio unit must be turned on and in radio tuner mode (AM/FM) to enter the speaker walk-around test (M100 only) or the DM100i or CDX6 self-diagnostic mode.
^ The DM100i or CDX6 self-diagnostic mode can only be entered while in the speaker walk-around test.

1. To enter the speaker walk-around test, depress preset buttons 3 and 6 simultaneously and hold approximately three seconds and release.
2. The Speaker Walk-Around Test stops at each speaker and applies sound to each speaker for about one to two seconds. Each speaker is tested and shown on the display in the following sequence: RF, LF, LR, RR.
3. To exit the speaker walk-around test, turn the ignition switch off, turn the audio unit off, or press preset buttons 1 for "DIA".
4. The DM100i and CDX6 Self-Diagnostic Mode has six manual tests available:
^ Preset button 1 = ENTER DIAGNOSTICS. This test enters diagnostics from the Speaker Walk-Around Test. Metrics are available with SEL and ON buttons indicating time played in AM/FM, media, number of buttons pressed, etc.
^ Preset button 2 = EEPROM BLOCK STATUS. This test shows validity of memory to calibrate the clock and seek sensitivity.
^ Preset button 3 = EXIT DIAGNOSTICS.
^ Preset button 4 = Software configuration level. This test queries each radio system controller for its software configuration level.
^ Preset button 5 = DISPLAY TEST. This test lights all the DM100i display segments for five seconds and then turns all segments off. Preset button 6 = RAM CONTENTS READOUT. To enter these tests, depress Preset button 1 while in the speaker walk-around test, then press the desired preset button.

NOTE: Always document, clear, and carry out the DM100i or CDX6 Self-Test again.

5. To exit the DM100i or CDX6 Self-Diagnostic Mode, turn the ignition switch off or turn the DM100i or CDX6 off.
