OVERVIEW

Would you like to watch television with crystal-clear sound that won’t disturb others in your family? Do you want to avoid hearing damage that could be caused by wearing normal wireless headphones for a long time? SIMOLIO SM-823 Pro wireless TV hearing assistance and protecting headphone is just made for you. Apply with the latest 2.4GHz Digital Automatic Frequency-Hopping Spread Spectrum (FHSS) technology, it gives you crystal-clear sound with the freedom of a wireless connection – up to 100 feet without obstacles. You can customize your listening at a most comfortable volume level, via balance and tone controls. Our voice highlighting and noise cancelling technology dynamically reduce TV background sounds and make TV dialogues stand out. At last you can easily understand the TV dialogues at a healthy volume without worrying about your hearing being damaged. The SIMOLIO SM-823 Pro is especially helpful for hearing-impaired people. It overcomes the weakness of regular hearing aids, which amplify both speech and environmental background at the same time. Normal wireless headphones for TV watching don’t help either, they also amplify everything together. What’s more, over time you’ll keep turning the volume up and up, and that can make your hearing worse and worse. Our hearing protecting headphone solves these problems. The unique “one-button push” sound amplifier function allows you to hear clearly what people are talking nearby without taking off the headphones.

Note: Please charge the headset for 3 hours before using it for the first time.

Connect the Transmitter to Your TV/ Audio Source
Set the audio output of your audio sources to a sufficient level to ensure the normal hearing level people can hear TV clearly. i.e. set the TV box VOL ≥ 30 % (Ref. Fig 3-1) & TV VOL ≥ 40% (Ref. Fig 3-2) For watching TV quietly without disturbing others, the right way is: Mute your TV by 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.

RCA Analog Connection

This part will instruct you on how to connect the SIMOLIO SM-823 transmitter to your television, satellite, or cable box using an RCA audio cable.

• 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.
• 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.

Step 1. Hook up SIMOLIO to the RCA Audio Out Port of the TV/other Audio Device

Plug the red and white ends of the audio cable into the analog RCA Audio Out ports (red and white ports labeled “AUDIO OUT”) on the back of the TV. Plug the single end of the audio cable into the port labeled “AUDIO IN” on the back of the transmitter.

Step 2. TV Audio Out Checking and TV Speaker Setting (use TV remote control)

If you can not hear sound from your headsets after connecting:

• Ensure use TV Red/White ports labeled “AUDIO OUT” or “OUTPUT”, other Red/White ports are incorrect. (Ref. Fig 3-5)
• Ensure your TV speaker is set to “External Speakers”. (Ref. Fig 3-6)

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.
  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 + Headsets”. And for some newer Samsung TVs, you can enable this feature by selecting “TV Speaker” from the TV Sound Output lists.

• 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-823 Pro volume level, you will need to make sure your TV is set to “Fixed”.Contact your TV manufacturer for assistance. (Ref. Fig 3-7)

• Setting menu may be different depending on different TV brands and models.

• 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-823 Pro 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.

Step 1. Hook up SIMOLIO to the 3.5mm Audio Out Port of the TV/other Audio Device
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.

Step 2. TV Audio Out / TV Speaker Setting (use TV remote control) If you can not hear sound from your headphones after connecting:

• Ensure your TV speaker is set to “Headset”. (Ref. Fig 3-9)
• Plug a wired headphone/earphone into the 3.5mm audio out port of the TV to test if you can hear the TV sound. (Ref. Fig 3-10)

Notes:

• Your TV’s audio settings may be set to “Variable” or “Fixed”. We recommend that you set your audio settings to “Fixed” for better audio quality when using this installation option. If you want to be able to control your TV volume level separate from your SIMOLIO SM-823 Pro volume level, you will need to make sure your TV is set to “Fixed”. Contact your TV manufacturer for assistance.
• Setting menu may be different depending on different TV brands and models.

Other Connections in Special Cases

1. TV/Audio Source only has Digital Coaxial Audio Out port Step 1. Purchase a Digital to Analog Converter and Set up as Shown inFig 3-12 If your TV/Audio Source only has a digital optical or digital coaxial audio out port, you will need a digital to analog converter (DAC) for installation.

Step 2. TV /Audio Format and Speaker Setting (use TV remote control) If you can not hear sound from your headphones after connecting:

• Ensure TV Audio Format is set to “PCM” or “Dolby/DTS” is OFF (This is IMPORTANT, Ref. Fig 3-13) PS: for certain smart Samsung models, the TV is retaining separate settings for regular TV and internet TV setup. When you turn to the Smart Hub for Internet source, please use the TV remote to go to Settings > Sound > Expert Settings > Audio Format or Digital Output Audio Format, then select PCM.
• Ensure your TV speaker is set to “External Speakers”. (Ref. Fig 3-14)
• Take turns to test RCA connection and 3.5mm headphone connection.
• Use a wired headphone/earphone to plug into the H/P port or RCA output of the DAC to test if you can hear the TV sound. (Ref. Fig 3-15)

Note:
Setting menu may be different depending on different TV brands and models.

Use SIMOLIO SM-823 Pro with your AV Receiver with 6.35mm PHONE jack

If you can not hear sound from your headsets after connecting:

• Use the 6.35 to 3.5mm converter to plug a wired headphone/earphone into the port on AV receiver to check whether the sound is normal.
