RF stands for Radio Frequency and means the remote is multi-directional. This benefit is why you'll now find IR/RF remotes for home-theater components. The remote control codes are sent to the receiver using the modulation rate. To check to see if your device is controlled by a RF (radio frequency) or IR (infrared) remote: Power the device on manually Cover the front of the original remote that came with the device with your hand Press any button on the remote that you know the device would respond to normally This range should not be confused with the modulation rate (carrier frequency) of the remote control. Introduction. 38 kHz. Push a button on the remote control and simultaneously take a picture of the front end of the remote control where the infrared light displays. These remotes use RF-to-IR converters to extend the range of an infrared remote. Select any of the following icons on the Settings menu to access the settings for that screen: The bulb actually emits a type of invisible light.Infrared Radiation (IR) is electromagnetic radiation with a longer wavelength than light that is visible to the average human eye. The spectral bandwidth of a typical IR diode is around 50 or 55 nm. At one point the set failed to respond to my remote and wouldn't turn off when I attempted to power it off using the set's power button. All IR remotes use the infrared frequency range (300 mHz - 400 gHz). However, IR remote controls do not output continuous infrared light. Please note, comments must be approved before they are published.
