セットアップ手順
Follow these steps to set up your IR Repeater System:
- Connect the IR Receiver: Plug the IR Receiver into one of the 3.5mm ports labeled "IR Receiver" on the distribution box. Position the IR Receiver in a location where it has a clear line of sight to your remote control.
- Connect the IR Emitters: Plug the dual head IR Emitters into the 3.5mm ports labeled "IR Emitter" on the distribution box. Each dual head emitter can control two devices.
- Position the IR Emitters: Carefully peel the adhesive backing from each IR Emitter and attach it directly over the IR sensor window of the device you wish to control. Ensure the emitter is securely placed and aligned with the device's IR sensor for optimal performance.

- 接続電源: Plug the 12V DC 500 MA power plug into the "DC 12V" port on the distribution box, then plug the power adapter into a standard electrical outlet. The power LED on the distribution box should illuminate.
- 接続を確認します: The IR Receiver has an indication light. A green light indicates power is connected. A red light will flash when an IR signal is received and transmitted by the emitters.
Important Note on IR Receiver Placement:
- If connecting two or more IR receivers, maintain a distance of at least 6 meters (approximately 20 feet) between them to prevent signal interference.
- Avoid placing the IR receiver directly next to your original set-top box's receiver window without covering the original window. Simultaneous reception by both the original device and the repeater can cause interference.
- Plasma displays emit IR frequencies that can cause interference. Position the IR receiver away from plasma TV screens.

操作手順
Once the system is set up, operating your devices is straightforward:
- Point your existing IR remote control at the IR Receiver.
- The IR Receiver will capture the signal and transmit it to the distribution box.
- The distribution box will then send the signal through the connected IR Emitters to your hidden devices.
- You should experience immediate and responsive control over your devices, even if they are out of direct line of sight.
メンテナンス
To ensure the longevity and optimal performance of your SZBJ IR Repeater System, consider the following maintenance tips:
- Keep the IR Receiver and Emitters clean and free from dust. Use a soft, dry cloth for cleaning.
- すべてのケーブル接続がしっかりと固定され、ねじれや損傷がないことを確認してください。
- Avoid exposing the components to extreme temperatures or moisture.
- Do not attempt to open or repair the distribution box or other components, as this may void any potential warranty.
