2. دليل الإعداد
Follow these steps to set up your NIORFNIO 15W FM Transmitter:
- فك المحتويات: Carefully remove all components from the packaging. Ensure you have the transmitter unit, magnetic sucker antenna, power adapter, and any included cables.
- اتصال الهوائي: Connect the magnetic sucker antenna to the "RF-OUT" port on the back of the transmitter. Ensure the connection is secure. For optimal performance and to prevent damage, always connect the antenna before powering on the device. Position the antenna on a metal surface (e.g., car roof, balcony railing) to create a ground plane, which enhances signal transmission.
- توصيل الطاقة: Connect the power adapter to the "12V===2A" input port on the back of the transmitter, then plug the adapter into a standard electrical outlet.
- مدخل الصوت:
- Via Audio Jack: Connect your audio source (e.g., MP3 player, computer, mixer) to the "Audio" input jack on the front panel using a 3.5mm audio cable.
- عبر البلوتوث: Power on the transmitter. On your audio device, search for Bluetooth devices and select "NIORFNIO" to pair.
- Via Microphone: Connect a microphone to the "MIC" input jack on the front panel.
- PC Control (Optional): To use PC control features, connect a micro USB cable from the "PC Control" port on the back of the transmitter to your computer. You may need to install specific drivers and software, which can typically be obtained from the manufacturer's support webموقع.

3. تعليمات التشغيل
Once set up, operate your transmitter using the following guidelines:
- تشغيل/إيقاف التشغيل: Press the "Power On/off" button (circular button with power symbol) on the front panel to turn the unit on or off. The display will illuminate.
- ضبط التردد: Use the "Up" (triangle pointing up) and "Down" (triangle pointing down) buttons to adjust the transmission frequency. The current frequency will be displayed on the LCD screen. Select a clear frequency not currently in use in your area to avoid interference.
- ضبط مستوى الصوت: Rotate the "Audio volume adjustment" knob (leftmost knob) to control the input audio level. Adjust this to prevent distortion while ensuring sufficient signal strength.
- ضبط مستوى صوت الميكروفون: If a microphone is connected, rotate the "Microphone volume adjustment" knob (rightmost knob) to control its input level.
- Power Output Adjustment: The transmitter supports 5W and 15W power output modes. Refer to the device's menu or PC control software for instructions on switching between these power levels. Higher power provides greater range but consumes more energy and generates more heat.
- Channel Switching (Stereo/Mono): The device supports switchable stereo and mono channels. This setting can typically be adjusted via the device's menu or PC control software. Stereo mode provides higher fidelity for music, while mono mode can improve clarity for voice broadcasts over long distances.
- تشغيل البلوتوث: After pairing, ensure your audio device's volume is set appropriately. The transmitter will broadcast the audio received via Bluetooth.
- PC Control Software: If using the PC control software, launch the application on your computer. This software allows for advanced settings, including frequency control, power output adjustment, and scheduling of broadcasts. Ensure the transmitter is connected via USB and recognized by the software.
