OPERATION
TROUBLESHOOTING
Move the Master Power switch (marked “Power” å) to the “•” (On) position to use the sub- woofer. The SUB500 subwoofer will automatically turn on or go into standby (sleep) mode when left in the auto mode (“Auto/On” switch ç in the “Auto” position). When your receiver or amplifier is off, or is not sending program material to the subwoofer, the sub- woofer will be in standby mode (LED will be red). When the subwoofer senses an audio sig- nal, it will automatically turn on (LED will be green). If the sub- woofer does not sense a signal after approximately 20 minutes, it will automatically go into standby mode.
When the “Auto/On” switch ç is switched to the “On” posi- tion, the subwoofer will remain on, whether or not program material is playing.
If you will be away from home for an extended period of time, or if the subwoofer will not be used, switch the Master Power switch å to the Off position.
