Troubleshooting
No piezo signal
Make sure that the jack connector
inside the guitar is connected properly.
There should be an audible“click“ when
the ball-ended jack safely sits in the 2.5
mm plug. It can take a little eort.
No mic signal
Please listen carefully rst as you may
just expect way more microphone than
we provide for good reasons and bare
in mind: in many cases the reference for
functionality is including the negative
bit… we are not proving this range as
we want to make sure that you can use
the microphone up to its best.
No output signal
Ensure that the battery still has enough
charge to operate the system
Ensure that the strap holder on the end-
pin is screwed on tightly. Strap move-
ments sometimes loosen the strap
holder (although the rubber O-ring
should prevent this) which may lead to
a contact fault in the endpin socket.

Plug-in endpin to the SHC: take care of the right
position. The little catch must be at the top side.
