Solution
Make sure the wall power outlet or power strip has
power. Make sure all switches for outlet/power
strip are on and that all switches for speaker
system are on.
Ensure that the correct source is selected; choose
FM radio as a source. Turn up the volume. Check
the system with a known good source, such as your
iPod. Connect the Aux In cable to the headphone
jack on your iPod.
Reposition your JBL On Time 400IHD unit until you
find better reception.
Check surrounding area for any possible
interference; wrap up any excess cables.
Make sure the iPod or Aux In cable is seated all the
way into the JBL On Time 400IHD unit.
Turn monitor off to see whether noise is eliminated.
Move JBL On Time 400IHD unit's cables farther
away from monitor.
Ensure that the unit is connected to an appropriate
source device. Make sure that all signal cables are
inserted snugly into receptacles.
Check volume of source device; some devices
will distort the output signal if the volume is set to
Maximum.
We recommend that the source device EQ be set
to Flat or Off.
Check input cable connection.
Wrap up excess input cable to make it as short
as possible.
Purchase a ferrite clamp and attach it over the
input cable; a clamp can be purchased at your local
electronics store.
