If that occurs, set the AUTOSTANDBY switch to the OFF position and use thePOWER switch to switch the power between ON andOFF manually.* This function detects the low-frequency componentsbelow 200 Hz of the input signals (i.e., the explosion inthe action movie, the sound of the bass guitar or the bassdrum, etc.).* The minutes required to switch the subwoofer to thestandby mode might change by sensing noise from otherappliances.This function is available only when the power of thesubwoofer is on (by pressing the POWER switch).If the source being played is stopped and the input signal iscut off for 7 to 8 minutes, the subwoofer automaticallyswitches to the standby mode. (When the subwooferswitches to the standby mode by the automatic power-switching function, the power indicator lights up in red.)When you play a source again, the power of the subwooferturns on automatically by sensing audio signals input to thesubwoofer.This function will operate by sensing a certain level of lowfrequency input signal. Usually set the AUTO STANDBYswitch to the LOW position. However, if the power is notswitched on or to the standby mode smoothly, set the switchto the HIGH position. In the HIGH position, the power willturn on even with a low level of input signal. But please beaware that the subwoofer may not switch to the standbymode when there is an extremely low input signal.
