Usage Tips:Analog TV signal transmitter/wireless RF signal converterResurrects old-fashioned againSmall, portable, and HDIt supports multiple devices to receive, meeting your different needs. Universal type for color and black and white televisionsMultiple input methods: Supports set-top boxes, network set-top boxes, computers and mobile phonesWith an OLED screen and an -compatible interfaceSupports 9V power suppliesPowerful performance with low energy consumptionIndustrial-grade motherboard360-degree coverage without dead endsHigh-performance processing chipsThe transmission distance is 10-20m/32.8-65.6ftSupports HD input. The HD input can be converted to N and P systems.AV input is supported, but it cannot be converted to N system.It supports high-definition input, converts it to AV signal output and then connects to other AV-enabled displays, such as LCD . At the same time, it can also send signals out.Supports accompanying sound setting in the range of 4.5MHz-6.5MHz.FM Transmitter:Simple FM signal transmission and the transmission effect is not bad. Here's how: set the frequency to 85.25MHz in the VHF band and change the frequency of the accompanying sound. 85.25MHz plus the accompanying sound frequency is equal to the radio's reception frequency.85.25MHZ+6.5MHZ=91.75MHZ85.25MHZ+6.0MHZ=91.25MHZ85.25MHZ+5.5MHZ=90.75MHZ85.25MHZ+4.5MHZ=89.75MHZColour:WhiteMaterial:Aluminum PlywoodPackage Contents:1 x Transmitter1 x Antenna1 Cord (5V Input Voltage)Only the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
