Transmitters were not installed in
channel order. Receivers automatically
assign transmitter channels to receiver
channels, from lowest to highest (see

sequence. You will need to reprogram
receivers as well.

electronics inside; replace the receiver.
The standalone receiver is designed to make changing the
headphone jack a quick and easy job, one easily done at the facility.
You will need a Phillips-head screwdriver, wire cutter, pliers, and two
new wire ties to reattach the receiver.
