3.1 Soldering Components
Begin by soldering the smaller components, including any Surface Mount Devices (SMD) if present, before moving to larger through-hole components. Ensure correct orientation for polarized components like LEDs and capacitors. The circuit board is clearly marked for component placement.
Figure 3: Soldering is required for assembly.
3.2 Assembling the Acrylic Casing
Once all electronic components are soldered and tested, assemble the clear acrylic casing. Carefully peel off any protective paper covering from the acrylic panels. Heating the panels slightly with a hairdryer can assist in easier removal of the protective film. Pay attention to the different screw lengths for securing the speaker and circuit board to ensure proper fit and alignment with the standoffs.

4. Foydalanish bo'yicha ko'rsatmalar
4.1 Quvvatni yoqish/o‘chirish
Press the power button to turn the radio on or off. The LCD display will illuminate upon power-on.
4.2 Searching and Storing Programs
To automatically search for FM stations, long-press the "AUTO" button. The radio will scan frequencies from 76-108MHz. When a station is found, it will be automatically stored in the memory chip for quick access later.
Figure 6: Automatic station search and storage.
4.3 Power Off Memory Function
The radio features a power-off memory function. When you turn the radio off, it will remember the last program or station that was playing. Upon turning the radio back on, it will automatically resume playing from that last station, eliminating the need to re-tune.
Figure 7: Power-off memory function.
4.4 Cool LED Flashing Lights
The radio is equipped with 5 LED lights that provide a dynamic visual experience. These LEDs will randomly flash different colors and pulse in sync with the beat of the music, enhancing your listening enjoyment.

4.6 Campus Broadcast and Backlight Settings
The radio offers advanced settings for campus broadcast and backlight control:
- Campus Broadcast Setting: In the power-off state, long-press the VOL+ and VOL- buttons simultaneously and then turn on the radio. If the LCD displays "C1", campus broadcast is enabled. If it displays "C0", campus broadcast is disabled. This setting takes effect after a restart.
- Orqa nuri sozlamalari: In the power-off state, long-press the P+ and P- buttons simultaneously and then turn on the radio. If "b1" is displayed, the LCD light will stay steady on. If "b0" is displayed, the LCD light will turn off after 20 seconds of inactivity to conserve power. This setting also takes effect after a restart.

5. Xizmat ko'rsatish
To ensure the longevity and optimal performance of your FM Radio Kit, follow these maintenance guidelines:
- Tozalash: Use a soft, dry cloth to clean the exterior of the radio. Avoid using abrasive cleaners or solvents, as they may damage the acrylic casing yoki elektron komponentlar.
- Saqlash: Radioni to'g'ridan-to'g'ri quyosh nuri va haddan tashqari haroratdan uzoqroq joyda, salqin va quruq joyda saqlang.
- Ishlov berish: Handle the radio with care to prevent damage to the circuit board or soldered connections. Avoid dropping the device.
- Quvvat: Always use a stable USB power source. Disconnect power when the radio is not in use for extended periods.
6. Muammolarni bartaraf qilish; nosozliklarni TUZATISH
If you encounter issues with your FM Radio Kit, please refer to the following common problems and solutions:
| Muammo | Mumkin sabab | Yechim |
|---|---|---|
| Radio yoqilmaydi. | Incorrect power connection; faulty soldering; component misplacement. | Ensure USB cable is securely connected to a working power source. Double-check all power-related solder joints and component orientations (e.g., diodes, capacitors). |
| Ovoz sifati past yoki statik. | Weak signal; antenna not extended; poor speaker connection; faulty audio components. | Fully extend the telescopic antenna. Try repositioning the radio for better reception. Inspect speaker wire connections and ensure they are securely soldered. Verify all audio-related components are correctly installed. |
| LED lights not flashing or incorrect behavior. | Incorrect LED polarity; faulty LED; soldering issue. | Check the polarity of each LED during assembly. Re-solder any loose connections to the LEDs. |
