Symptom
Sound only heard on one side
(left or right)
My class is larger than eight students.
The control unit appears to be frozen.
Lights do not turn on or off, unable to
change settings.
Solution
Ensure that the instrument is connected from the
headphone output to instrument input L/Stereo
jack on instrument box.
Check to see if LC4 Hub is set to “Split Mode.”
If so, turn off and see if symptom persists.
Change cables or headphones with ones that are
known to work to see if symptom persists. If not,
then you might have a failed part. Contact customer
support for information about replacement or repair.
Utilize “Split Mode” with compatible instruments*
and purchase additional CM500 headsets.
Purchase LC4EXP expansion package which is
all-in-one box to add eight more students to your
LC4BASE.
Turn hub unit power off on and then back on.
If power on/off does not remedy the situation,
power off and then on while pressing the reset
button; use an unbent paperclip inserted into the
tiny hole on the back of hub to press the button.
