HY STB remote control
The difference between infrared remote control and wireless remote control: infrared remote control is used to transmit control signals, it is characterized by directivity, you need to aim at the remote control. The radio remote control, which uses radio waves to transmit control signals, is characterized by directionlessness.

HY Light IR Remote Control
The principle of the LED Light IR remote control is to use the remote control’s infrared transmitter tube to convert the signal into invisible infrared sent out, and then the remote control object is connected to the infrared receiving head to receive the infrared and then convert it into a signal, and then the signal can adjust the object.

HY Customized TV Remote Control
Operation of infrared remote control:
First of all, the principle of the infrared remote control is that the transmitting head transmits signals, the receiving head receives signals, this is obvious, everyone knows. The transmitter transmits the modulated signal, this point also needs to be clear, that is, the encoded carrier signal.
Remote control no matter learning, or actual work, is the transmission of signals. When learning, the signal of each protocol is transmitted, because the receiving head can only receive the fixed protocol, so only the fixed protocol will respond.
In actual operation, there will be overlap. At this time, you will find that there is some misoperation. -
Hua Yun 43 Key Bluetooth Voice Remote Control HY-142
The Bluetooth voice remote control mainly relies on Bluetooth wireless data transmission to realize the remote control function. In terms of voice search and input, it is mainly realized through the built-in microphone of the remote control. The chip processes the recognition of voice and the related data.

Hua Yun 49 key wireless infrared TV remote control HY-044
The remote control is used for a long time, and the conductive sheet of the key is dirty, leading to the failure of the key.
The emergency solution is to carefully open the back cover of the remote control, dip a cotton swab with alcohol, wipe the conductive rubber on the plastic key piece and the printing surface of the printing board. Black material will be left on the cotton swab, and then replace the cotton swab and wipe again until there is no more black material. Then reinstall the remote control.
