3. Kurulum Talimatları

  1. Connect AV Source: Connect your AV source (e.g., set-top box, DVD player) to the modulator's CVBS (yellow) and L/R Audio (white/red) input ports using standard RCA cables.
  2. Televizyona bağlanın: Connect the "RF out" port of the modulator to the "RF in" (antenna/cable) port of your television using a coaxial cable. If you have an existing antenna or cable signal, connect it to the "RF in" port of the modulator, then connect the "RF out" to your TV.
  3. Connect IR Emitter (Optional): If using the IR extender function, plug the IR Emitter cable into the "IR Emitter" port on the modulator. Position the IR emitter head near the IR receiver window of your AV source device (e.g., set-top box) to allow remote control signals to pass through.
  4. Güç Açık: Connect the USB power cable to the "USB 5V" port on the modulator and plug the other end into a 5V USB power adapter (not included) or a compatible USB port on your TV or other device. The channel display should light up.
  5. Tune TV: Turn on your television and perform an automatic channel scan or manually tune to the output channel selected on the modulator. Use the CH- and CH+ buttons on the modulator to select the desired output channel. Ensure your TV is set to the correct input source (Antenna/Cable).

4. Kullanım Talimatları

  1. Kanal Seçimi: Use the "CH-" and "CH+" buttons on the modulator to cycle through available output channels. The selected channel will be displayed on the digital display. Ensure your television is tuned to this same channel.
  2. PAL/NTSC Selection: The modulator supports both PAL and NTSC. The system automatically detects the input signal format. If manual adjustment is needed, refer to the device's specific settings (not explicitly detailed in provided data, but implied by "PAL optional").
  3. IR Extender Usage: Once the IR Emitter is correctly positioned and connected, your existing remote control for the AV source device will function through the modulator, allowing you to control the source from a different room or location where the TV is located.
  4. TV Link Signal: The "TVlink Signal" and "TVlink on/off" feature (if present and active) is typically used in conjunction with specific TV link systems to provide power or control signals over the coaxial cable. Consult your TV link system's documentation for compatibility and usage.
