SOURCE CONNECTIONS
analog: Use the supplied stereo audio cable to connect the soundbar’s Source 1 (analog) input to your TV’s stereo audio output. If your TV has two sets of audio output jacks, use the set that has a fixed (not variable) output level. This will let you turn your TV’s speakers all the way off while the TV still supplies a constant audio signal to the soundbar.  digital: If your DVD player, cable tuner or satellite tuner has an optical digital output, you can use an optical digital audio cable to connect it to the soundbar’s Source 2 (optical digital) input.
TURNING THE SUB-WOOFER ON & OFF
Set the subwoofer’s Power switch to the “On” position. The subwoofer will automatically attempt to establish pairing with the soundbar (the subwoofer’s LED will flash blue). If pairing is not established within one minute, the subwoofer will enter the Standby mode (its LED will turn amber). If pairing is established, the subwoofer will turn on (its LED will light blue continuously).  The subwoofer will remain on for approximately one minute after the soundbar enters the Standby mode, or for approximately 15 minutes after the audio signal ceases.
