Features: 1. Product Classification SCART to RF converter that changes SCART interface to radio frequency RF output. 2. Function Introduction The RF converter easily converts your device's interface into RF output, modulating it into high-frequency RF signal. It reduces transmission loss, extending transmission distance from 1–2 meters up to 100–1000 meters or more. It also helps overcome limitations of older TV interfaces by utilizing the TV’s built-in tuner. Compatible with DVD players, set-top boxes, network boxes, game consoles, and similar devices. Features imported RF modulation chip for stable PLL frequency phase-locked RF output, ensuring consistent frequency without drift. 3. Technical Specifications RF output frequency: 61.25 MHz and 67.25 MHz (switchable); customizable frequencies between 40–900 MHz available RF output gain: 80 dB RF system output: PAL DK (default); customizable to I, BG, M, N, L sound systems; SECAM and NTSC systems available for region-specific compatibility Power supply: 5V / 500mA Power consumption: less than 0.5W 4. Usage and Connection Connect the RF converter to your device’s output interface and power it via USB. Connect the included RF cable from the converter’s RF OUT to the TV’s RF IN (antenna or cable input). Turn on the TV and switch to analog TV mode. Use the menu button to perform an automatic or manual channel search for 61.25 MHz or 67.25 MHz. Set the sound system to PAL DK for proper audio. Smart TVs typically detect the sound system automatically. For older TVs, manually set the sound system to DK to avoid image and sound interference.
