FORD 2010 F-550 v.2 - Manual (Page 60)

Troubleshooting:
1. Do not connect the audio input jack to a line level output. Line level
outputs are intended for connection to a home stereo and are not
compatible with the AIJ. The AIJ will only work correctly with devices
that have a headphone output with a volume control.
2. Do not set the portable music player’s volume level higher than is
necessary to match the volume of the CD or FM radio in your audio
system as this will cause distortion and will reduce sound quality. Many
portable music players have different output levels, so not all players
should be set at the same levels. Some players will sound best at full
volume and others will need to be set at a lower volume.
3. If the music sounds distorted at lower listening levels, turn the
portable music player volume down. If the problems persist, replace or
recharge the batteries in the portable music player.
4. The portable music player must be controlled in the same manner
when it is used with headphones as the AIJ does not provide control
(play, pause, etc.) over the attached portable music player.
5. For safety reasons, connecting or adjusting the settings on your
portable music player should not be attempted while the vehicle is
moving. Also, the portable music player should be stored in a secure
location, such as the center console or the glove box, when the vehicle is
in motion. The audio extension cable must be long enough to allow the
portable music player to be safely stored while the vehicle is in motion.
USB port (if equipped)
