This part will explain how to connect the SIMOLIO SM-621 transmitter to
your television, satellite, or cable box using an RCA analog audio cable.
• If you cannot get to the back of your TV and you only watch the programs

3. Connect the Transmitter to Your TV/Audio Source
Set the volume of the audio source to a level sufficient for people with normal
hearing to clearly listen to the TV to ensure stable audio output.
i.e. set the TV box VOL ≥ 30 % & TV VOL ≥ 40% (Ref. Fig 3-1) (Ref. Fig 3-2)
For watching TV quietly without disturbing others, the right way is: Mute your
TVby pressing the MUTE button on the remote control or choose any speaker
option other than TV Speaker in the TV Sound Output settings.(Ref. Fig 3-3)
• The above settings may differ from various TVs.
