Important Assembly Notes:

• Ensure all components are correctly oriented and placed in their designated positions on the circuit board.
• Thoroughly check all solder joints for proper connection and to avoid cold joints or bridges. Poorly connected solder joints can prevent the device from functioning correctly.
• Refer to the detailed instructions provided with the kit for step-by-step guidance on component identification and soldering order.

Operating Instructions

Once assembled, your FM radio is ready for operation. This section details how to power on the device, adjust settings, and utilize its features.

Power Supply Modes

The radio supports two power supply options:

• USB Power: Use the included USB cable to connect the radio to a compatible USB power source (e.g., a computer USB port, a USB wall adapter, or a power bank). The working voltage is 3V/5V.
• Battery Power: For portable use, you can install batteries into the battery case. Batteries are not included and must be purchased separately.

Headphone Jack

The radio is equipped with a 3.5mm headphone jack, allowing for private listening. Simply plug in your headphones (not included) to enjoy audio without disturbing others.

Adjusting Channels and Volume

The radio features an LED display to show the current channel frequency and volume level. Use the control buttons and potentiometer for adjustments:

• Buttons: Adjust channels and overall volume using the dedicated buttons on the front panel.
• Potentiometer (R1): Fine-tune the volume by rotating the potentiometer labeled R1. This allows for precise control over the audio output.

Maintenance

Proper maintenance ensures the longevity and optimal performance of your FM radio kit.

• Cleaning: Use a soft, dry cloth to clean the acrylic casing and circuit board. Avoid using abrasive cleaners or solvents, which can damage the materials.
• Storage: Store the radio in a cool, dry place away from direct sunlight and extreme temperatures.
• Handling: Handle the assembled radio with care to prevent damage to the electronic components or solder joints.

Troubleshooting

If you encounter issues with your FM radio kit, consider the following troubleshooting steps:

• No Power/No Display:
  • Ensure the USB cable is securely connected and the power source is active.
  • If using batteries, check that they are correctly inserted and have sufficient charge.
  • Verify the ON/OFF switch is in the 'ON' position.
• No Sound/Poor Sound Quality:
  • Check the volume level using both the buttons and the R1 potentiometer.
  • Ensure the antenna is fully extended for optimal signal reception.
  • If using headphones, ensure they are fully plugged into the 3.5mm jack.
  • Inspect all solder joints, especially those connected to the speaker, headphone jack, and main ICs, for any cold joints or short circuits. Re-solder if necessary.
• Unable to Tune Channels:
  • Confirm the antenna is extended.
  • Ensure all components related to tuning (e.g., variable capacitors, if any, or tuning buttons) are correctly soldered and functioning.
• General Malfunction:
  • The most common issue with DIY kits is soldering errors. Carefully re-examine all solder points for proper connection, especially for small components.
  • Verify that all components are placed in the correct orientation (e.g., electrolytic capacitors, diodes, integrated circuits).
