Step 2. TV Audio Out Checking and TV Speaker Setting (use TV remote
control)
If you can not hear sound from your speaker after connecting:
Notes:
* If your TV only support single sound out, the TV’s speakers will be either
automatically muted when you plug something into an audio out port (Optical/
AUX/RCA, etc.) or they become disabled once you choose "External Speakers"
as your TV's audio output. It depends on TV circuit design.
• Ensure use TV Red/White ports labeled “AUDIO OUT” or “OUTPUT”,
other Red/White ports are incorrect. (Ref. Fig 3-9)
• Ensure your TV speaker is set to “External Speakers”. (Ref. Fig 3-10)
For most TVs, the TV's internal speakers and an external audio device can
work simultaneously. Such as, for some newer LG TVs, when do analog RCA
audio connection, you can set the “Sound Out” to “Internal TV Speaker +
Headphones”. And for some newer Samsung TVs, you can enable this feature
by selecting “TV Speaker” from the TV Sound Output lists.

This part is an alternative to 3.1 and 3.2 on page 8-10. This part will explain

Plug one end of the 3.5mm audio cable into the “Audio Out” port on the back
of the TV. Plug the other end of the audio cable into the port labeled “AUDIO
IN” on the back of the transmitter.
• If you cannot get to the back of your TV and you only watch the programs
through a fixed TV box (cable/satellite box/DVD etc.), you can also use these
instructions to install the system to your TV box.
• If you connect the 3.5mm audio cable to the 3.5mm Audio Out port which is
usually a Headphone port on your TV, your SIMOLIO SM-621D will still
function properly, but the sound to your TV internal speakers will be muted.
The port is usually labeled with an headphone icon.
• Be aware that the base should be placed at least 4 feet away from your
Router/smart WiFi TV/TV sticks/WiFi TV box to avoid interference.
*Setting menu may be different depending on different TV brands and models.
Step 1. Hook up SIMOLIO to the 3.5mm Audio Out Port of the TV/other
Audio Device
* Your TV’s analog audio settings may be set to “Variable” or “Fixed”. If you
want to be able to control your TV volume level separate from your SIMOLIO
SM-621D volume level, you will need to make sure your TV is set to “Fixed”.
