3. Setup and Assembly

This section outlines the steps for assembling your RDA5807 Radio Kit. Basic soldering skills and tools (soldering iron, solder, wire cutters, etc.) are required.

3.1. Soldering Components to PCB

1. Identify Components: Carefully identify each component using the provided component list and the markings on the PCB.
2. Solder Low-Profile Components First: Begin by soldering components that lie flat on the PCB, such as resistors, diodes, and small capacitors. Ensure correct polarity for diodes and electrolytic capacitors.
3. Solder IC Sockets (if applicable) or ICs: If your kit includes IC sockets, solder them first. Otherwise, carefully solder the Integrated Circuits, paying close attention to the orientation (notch or dot indicating Pin 1).
4. Solder Larger Components: Proceed with soldering larger components like the RDA5807 module, buttons, switches, 3.5mm earphone jack, and the digital display module.
5. Connect Speaker and Antenna: Solder the speaker wires to the designated pads and attach the telescopic antenna.
6. Solder Power Connectors: Solder the USB power input and battery holder connectors.
7. Inspect Solder Joints: After soldering all components, carefully inspect each joint for cold solder joints, bridges, or poor connections. Re-solder as necessary.

3.2. Assembling the Acrylic Casing

1. Remove Protective Film: Peel off the protective film from both sides of all acrylic casing panels.
2. Mount PCB: Carefully align the soldered PCB with the standoffs on the bottom acrylic panel. Secure it with the provided screws.
3. Assemble Side Panels: Attach the side panels, ensuring that all ports (USB, earphone jack) and buttons align with their respective cutouts.
4. Attach Top Panel: Place the top acrylic panel, ensuring the antenna and display fit through their openings.
5. Secure with Fasteners: Use the remaining screws and nuts to firmly secure the entire casing. Do not overtighten.

4. Operating Instructions

4.1. Powering the Radio

The radio can be powered by two methods:

• USB Cable: Connect the provided USB cable to the radio's USB port and a 5V USB power source (e.g., computer USB port, USB wall adapter).
• AAA Batteries: Insert three (3) AAA batteries (not included) into the battery holder, ensuring correct polarity.

Note: Do not use both USB power and AAA batteries simultaneously.

4.2. Basic Operation

The radio features four buttons for control:

• Power Button: Typically located on the side or front, press to turn the radio ON/OFF.
• Frequency Up (F+): Press to increase the radio frequency.
• Frequency Down (F-): Press to decrease the radio frequency.
• Volume Up (V+): Press to increase the volume.
• Volume Down (V-): Press to decrease the volume.

The digital display will show the current FM frequency (87-108 MHz).

4.3. Using Earphones/External Speakers

Connect standard 3.5mm earphones or external speakers to the earphone jack on the side of the radio for private listening or amplified sound.

5. Maintenance

• Cleaning: Use a soft, dry cloth to clean the acrylic casing. Avoid abrasive cleaners or solvents.
• Battery Replacement: If using batteries, replace them when the radio's performance degrades or it fails to power on. Ensure correct polarity when inserting new batteries.
• Storage: Store the radio in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.
• Component Check: Periodically check solder joints for any signs of cracking or corrosion, especially if the radio is frequently handled or exposed to vibrations. Re-solder if necessary.
