Thermal overload of the output stage or internal unit error

What does 11 mean?

The output stage of the unit has experienced thermal overload, or an internal error has occurred. This suggests that the operating temperature of the output stage is too high due to ambient conditions, inadequate heat dissipation, or excessive drive load, risking hardware damage.
