Solution
Plug the universal power supply into a wall outlet and plug the power supply
connector into the power supply jack.
If the universal power supply cord is plugged into a surge protector, make sure
the surge protector is switched on.
Plug another device into a wall outlet (same outlet) to confirm the outlet
is working.
Press the stand-by button (LED will turn on).
Install eight fresh D batteries into the battery compartments located on the
bottom of the inMotion iM7 system. Make sure the batteries are installed per
the illustration in the battery compartments.
Press the stand-by button (LED will turn on).
Verify the universal power supply cord is plugged into a wall outlet and the
power supply jack.
Verify batteries are installed if the universal power supply isn't being used.
Verify stand-by button has been pushed and the LED is illuminated.
Press the "+" button on the iM7 or the iM7 wireless remote control to increase
the volume.
Check volume level on alternate audio source device and set at mid-level.
Turn off the iPod, remove it from the docking station, reseat it, and turn it
on again.
Connect 3.5mm stereo cable to the audio source. Make sure the signal cable is
inserted firmly into the correct jacks.
Make sure the 3.5mm stereo cable is connected and fully inserted in the
"line-out," "audio-out," or the headphone jack on your audio source.
Test the speakers on another audio source by removing the 3.5mm stereo cable
from the audio source and connecting it to the "line-out," "audio-out" or the
headphone jack of a different audio source (e.g., CD player, MP3 player).
Check connection if iPod is in the docking station. Check connection of the
3.5mm stereo cable. Make sure it is connected to "line-out," "audio-out," or
the headphone jack on your audio source — and NOT "speaker-out."
Unplug the 3.5mm stereo cable from the audio source. Then plug it into the
headphone jack of an alternate source (e.g., CD player, MP3 player).
Press the "–" button on the iM7 or the iM7 wireless remote control to decrease
the volume.
WAV and .MID files are often of poor quality; therefore distortion and noise
are easily noticed with high-powered speakers. Try a different audio source
such as a music CD.
Check the operating system volume level and decrease if necessary.
Move your speakers to see if the interference goes away.
Replace battery.
Point the Remote Control toward the IR window, within 15 feet of the unit.
