Answer / carl_ellis

In the manual (from which you cited) the user action for
error 15 is 'contact service personnel'.

You can try that, but I suspect that it means, for all
practical purposes, replace the transmitter. I don't know
if Yoko offers a spare 'puck' that can be replaced in order
to salvage the housing and display, or not. You'll have
to ask.

You might try cycling power to it to see if an electrical
spike on the loop wiring adversely affected the processor,
and cycling the power might re-initialize it, but the
likelihood of success is very small.

When a transmitter goes to fail-safe mode, it's usually the
last act of the last performance, the actors are clasping
hands, and taking a final bow before the show closes.
