iPod Screen Check
1. In the Language screen, English should be highlighted. Click the Select button to
select it. The iPod mini screen appears.
2. Make sure the screen displays properly with no pixels missing.
3. Check for “rainbow effect” by looking straight at the iPod display screen, without tilting.
If a rainbow effect (Newton Ring effect) appears and is larger than 1 square cm, reject
the iPod.
4. If the screen is too dark or too light, adjust the Contrast from the Settings menu to get
a normal contrast.
Note: If the adjusted contrast is less than 25% (less than a quarter of the contrast
bar) or more than 75% (more than 3 quarters of the contrast bar) then reject the unit
for “Contrast excessive adjustment.”
Control Buttons & Audio Test
1. Use the Click Wheel to scroll up and down the menu. Make sure that you hear the
clicker sound when rotating the Click Wheel.
2. Connect headphones to the iPod, and orient the left and right sides correctly.
3. Navigate to the “Channel Check” playlist (this contains the downloaded
“ipod_ChannelCheck.mp3” file), and press Select.
4. Make sure the ipod_ChannelCheck audio file is selected, then press the Play button.
5. Listen for any distortion. Make sure the left and right channel messages are heard on
the appropriate side.
6. Navigate to the “iPod Testing” playlist, and start playing the songs.
7. Use the Click Wheel to vary the volume to ensure it works properly.
8. Press the Next button to play the next song, and play it for about 5 seconds.
