[PRTCT], [PUSH], speaker name ([FL], [FR], [RL], [RR], or [SUB]), and [POWER] flash alternately in the front panel display.

Press (power) on the corresponding speaker ([FL]: left front speaker, [FR]: right front speaker, [RL]: left rear speaker, [RR]: right rear speaker, [SUB]: optional subwoofer) to turn each off. For the speaker, disconnect the AC power cord (mains lead), then restart the speaker system. For the optional subwoofer, disconnect the AC power cord (mains lead) and make sure nothing is obstructing the ventilation holes of the optional subwoofer, then restart the speaker system. If they are reconnected properly, the display in the front panel display returns to the normal display.
