Notice:
When the unit is operated to extremes, such as with maximum power output for a long time, or
the temperature is over 70°C , it will enter heat protection mode and the volume will be reduced
automatically. This is normal.
Due to continuous product development, specifications may be subject to change without prior
notification.
