The TV Sound might be plugged into the headphone jack, which often disables the TV's built-in speakers.

Connect to the TV's RCA audio output

If the TV Sound is plugged into the TV's headphone jack, unplug it and use the RCA (red/white) audio output ports instead (ports will be labeled 'Audio out' on the TV). An RCA (red/white) to 3.5mm stereo cable is included with the TV Sound.

Use a digital optical audio output

It is recommended to always use the digital audio output on the TV for connecting the TV Sound. If available (port is labeled 'Digital audio out (optical)' or 'Audio out (optical)' on the TV, use the supplied optical (toslink) cable to connect the TV Sound. Unplug the analog cable if it's still plugged into the TV Sound and the TV. Consult with the TV's user manual or manufacturer for assistance with locating the optical audio out port. 

Change your TV's audio settings

Go to your TV's audio settings and enable the option for the TV speakers to be used simultaneously with external audio outputs

The TV is not set to output sound through the optical out connector.

Go to your TV's sound settings, and ensure the audio output is set to Digital Audio Out or Optical. This option is often located under Advanced Settings or Sound > Output Settings, depending on the TV model. If still having trouble finding the correct settings, consult with the TV's user manual or contact the TV manufacturer's support team.

If the TV Sound's LED is still blinking green even though the volume of the TV is increased to an adequate level, chances are the red/white RCA ports on the back of the TV are Inputs instead of a dedicated Audio output. The ports on the back of the TV should be labeled as a group. Make sure the red and white ports being used are labeled as 'Audio out' and not grouped with any other RCA ports with different colors (e.g. yellow, green, blue).

If there are no red/white RCA ports labeled 'Audio out', try looking for a port labeled 'Audio out (optical)' or 'Digital audio out (optical)'. If located, use the supplied optical (toslink) cable instead. 

If there is no optical output, try looking for a headphone jack. If located, you can use a 3.5mm to 3.5mm stereo cable (not included) to connect the TV Sound to that port. Do note that this will mute the TV speakers.

If no audio outputs can be found, consult with the TV's user manual or the TV manufacturer's support team for assistance locating audio output options.

The device is overheating.

Keep the device out of direct sunlight. Avoid placing the TV Sound near windows or in sunlit areas.
Do not place it in a closed drawer or cabinet. Ensure proper ventilation by keeping the device in an open space with airflow.

Avoid placing it near heat sources. Keep it away from TV heat vents, gaming consoles, or other electronics that generate heat.

If the TV is playing media and the LED on the TV Sound is solid green, let's start by trying the following:

Pair the hearing aids to the TV Sound

If the hearing aids have been paired to another device (e.g. a smartphone), turn Bluetooth off on that device. Next, turn the hearing aids off and on. When the hearing aids turn on, place the hearing aids on top of the TV Sound. If you see a series of pulsing blue lights, that means the TV Sound is pairing to the hearing aids. Once you see the solid green light again, put the hearing aids in your ears. You can now turn on the Bluetooth in previously paired devices. Try to stream from the TV Sound using the Signia app, the buttons on the hearing aids, or the prescribed method by your hearing care professional.

Initiate streaming in the hearing aids

Streaming from the TV Sound doesn't occur automatically. You can start the TV Sound stream in three ways:

1. If the Signia app is connected through Bluetooth, open the app and tap on the Stream option at the bottom. Tap on the Play button to begin streaming. Top stop streaming, tap on the Pause button.
2. Streaming can be started by changing to the TV hearing program. If your hearing care professional programmed a TV program in the hearing aids, switch to that program using the Signia app, the buttons on the hearing aids, or a paired remote control. To stop streaming, switch away from the TV program.
3. The buttons on the hearing aids can be programmed to specifically start and stop streaming from the TV Sound. Consult with your hearing care provider to find out if this was done and if so, if the press pattern is a short or medium press.

Increase the volume of the TV Sound stream

The volume of the TV Sound stream can be adjusted using the Signia app. If the Signia app is connected through Bluetooth and you are currently streaming from the TV Sound, go to the Stream section in the app. There should be a slider for TV Streaming. Use that slider to increase the volume of the TV Sound stream. Do note that the sliders in the Volume section of the app will also increase the volume of the TV Sound stream to a degree, but it will also increase the level of the hearing aid microphones (i.e. how loud the ambient sounds are) whereas the slider in the Stream section will only affect the TV Sound stream.

Reset the TV Sound and re-pair the hearing aids

Hold the reset button on the bottom of the TV Sound until the LED on top turns off. Let go of the button and you will see a blinking blue light. If your hearing aids have been paired to other devices (e.g. a smartphone), turn Bluetooth off on those devices. Turn the hearing aids off and back on and place them on top of the TV Sound. A series of pulsing blue lights will show up during the pairing process. After pairing is completed and the TV Sound shows a solid green light again (make sure the TV is on and playing something), you can enable Bluetooth on previously paired devices again. Try streaming again.

Ensure the hearing aid battery is not near empty

If using the Signia app, check the battery status of the hearing aids. If the hearing aid batteries are low and rechargeable, charge the hearing aids for at least 30 minutes and then try streaming again. If the hearing aids use exchangeable batteries, try new batteries.

The TV Sound or streaming device is placed in a drawer, behind a wall, or blocked by objects.

Place the TV Sound in clear line of sight. Make sure there are no physical obstructions between your hearing aids and the device.

Move closer to the TV Sound

Stay within the recommended wireless range (typically up to 10 meters / 30 feet).

Avoid areas with heavy wireless interference

Move the TV Sound away from other electronic devices that might interfere with the signal.

Make sure the audio cables are plugged in tightly and not damaged

If using the analog RCA to 3.5mm cable, make sure both ends are plugged in tightly. Try to unplug and replug them to reseat the connection. If using the optical (toslink) cable, ensure the cable is not kinked. Unplug the cable and swap ends to reverse and reseat the connections (ends are identical). 

When using the optical connection, the TV Sound's analog input turns into an optical output to connect other audio devices to. If a soundbar is plugged into the TV's optical audio port already, unplug the soundbar's optical cable from the TV and the soundbar. Plug the TV Sound into that same port using the supplied optical (toslink) cable. To connect the soundbar to the TV Sound, a minitoslink to toslink cable is needed (not included). Once acquired, the minitoslink side will plug into the TV Sound's analog port (purple port). The other end of the cable will be a regular optical (toslink) plug and will plug into the soundbar's optical port. Now both the TV Sound and soundbar will receive the TV's audio signal.
