Notes about the protection circuits

This unit has an output short circuit protection circuit, an overheating
protection circuit and a direct current protection circuit built-in.
A protection circuit is active when the power indicator blinks blue or
alternately blue and purple.
o If the power indicator blinks blue, a short might have occurred
with the +/− speaker cables. In this case, turn the power off and
check the speaker cable connections.
o If the power indicator blinks alternately blue and purple, the
internal temperature is high. Turn the unit off and wait a while for
the temperature to decrease. You can also change the installation
conditions to improve ventilation.
o If the power indicator blinks alternately blue and purple for 30
seconds, the unit will automatically turn itself off. After this, the
POWER button will be disabled for as long as the internal tem-
perature remains high.
If the indicator continues to blink even after likely causes have been
eliminated, contact the store where you purchased the unit.
