What is a TV hearing aid?

The TV hearing aid is specially designed for hearing-disabled people to listen to TV, mobile phone (or other audio devices). Not only TV hearing aid, but also mobile phone call aid. It can help to listen to, mobile phone sound clearly while other hearing aids can’t do it. In the market, hearing-disabled people can only find some normal wireless headphones for watching TV or listening to mobile phones, the worst thing is that it will make their hearing ability worse and worse by only adjusting the volume louder for a long time. Our VR hearing aid can solve the above problems.
Besides the strong wireless listening function, it is a perfect hearing aid and a wired hearing-improving headphone. You can use it with a normal telephone, or a mobile phone, and even listen to music, listen to the radio, etc.

Brief introduction

Set up and user instructions

Wireless TV hearing aid function

1. Connect the power adapter with the transmitter’s power jack.

2. Connect the 3.5mm plug of Audio cable 1 to the transmitter’s audio-in jack, connect the lotiform plugs to AUDIO OUT jack of TV, DVD, STB, etc. ( if it is a computer, you need to connect lotiform plugs with Audio cable2, then connect the 3.5mm plug of Audio cable2 to the speaker jack of the computer.) If the TV is used with a STB, DVD, etc., please prior to connect the transmitter with the STB, DVD, don’t connect to the TV set directly. (Maybe there isn’t audio out signal for some TVs when connect to them directly because manufacturers of TVs are different. If the sound source has a digital audio output, connect the optical socket of the sound source with the optical fiber cable. (Just for JH-8014A/B only)If the sound source doesn’t have any of the audio out jack mentioned above, just plug the microphone cable into the MIC IN socket of the transmitter, then fix the microphone on to the audio source’s speaker.

The indicator will light up on the transmitter in different statuses as below:

• The right indicator is lit blinking red for models A & B when the transmitter is switched on.

• For A model: Left lit red for only charging the receiver in the charging bay. Left lit orange (green & red together) for charging the receiver in the charging bay and the Li-ion battery in the compartment at the same time. Left lit green for only charging the Li-ion battery in the compartment.

• For B model: Left lit green for only charging the receiver in the front charging bay. Left lit red for only charging the receiver in the rear charging bay. Left lit orange (green & red together) for charging two receivers in two charging bays at the same time. Left lit green for only charging the Li-ion battery in the compartment.

Remark:
