7. Auto/On

If switched to auto, the subwoofer will remain in standby mode until a signal is detected at the input. The unit will then automatically switch itself on. It will then automatically return to standby mode if no input signal is present for approximately 5 minutes. With the switch in the 'ON' position the unit remains permanently on as long as the main power switch is on. The LED positioned on the rear panel indicates whether the unit is on or in standby mode (red for standby and green when on). The blue front panel LED indicates the unit is on and working.
