Step-by-Step Assembly

1. Identify Components: Lay out all the wooden enclosure panels, the Printed Circuit Board (PCB), speaker, battery compartment, and control knobs.
2. Assemble Enclosure Base: Begin by interlocking the base and side panels of the wooden enclosure. The jigsaw design ensures a snug fit.
3. Install Speaker: Carefully place the speaker into its designated circular opening on the front panel.
4. Mount PCB: Position the PCB inside the partially assembled enclosure. Ensure the shafts for the tuning and volume controls align with their respective holes on the front panel.
5. Attach Knobs: Securely push the tuning and volume control knobs onto their shafts protruding from the front panel.
6. Connect Antenna: Attach the telescopic antenna to its designated port on the PCB.
7. Integrate Battery Compartment: Place the battery compartment into its designated slot within the enclosure.
8. Complete Enclosure: Secure the remaining wooden panels, including the top and back, to fully enclose the radio components. Ensure all panels are firmly interlocked.

Battery Installation

1. Locate the battery compartment, typically on the back or bottom of the radio.
2. Open the battery compartment cover.
3. Insert 3 AA batteries, ensuring correct polarity (positive '+' and negative '-' ends) as indicated inside the compartment.
4. Close the battery compartment cover securely.

Operating Your Radio

Power On/Off and Volume Control

To turn the radio on, rotate the VOL. (Volume) knob clockwise. Continue rotating clockwise to increase the volume. To decrease the volume and turn the radio off, rotate the knob counter-clockwise until it clicks into the 'OFF' position.

Tuning to Stations

Rotate the TUNING knob to scan through available AM or FM frequencies. The frequency scale on the front panel indicates the approximate broadcast frequency. Adjust slowly for best reception.

AM/FM Band Selection

Use the AM/FM switch, typically located on the side of the radio, to select between Amplitude Modulation (AM) and Frequency Modulation (FM) bands.

Using the Auxiliary Input

To play audio from an external device, connect it to the 2.5mm AUX IN port using a compatible audio cable. The radio will automatically switch to play audio from the connected device. Ensure the external device's volume is adjusted appropriately.

Antenna Adjustment

For optimal FM reception, fully extend and adjust the angle of the telescopic antenna. For AM reception, the internal antenna is generally sufficient, but rotating the entire radio's position may improve signal quality in some areas.

Maintenance

• Cleaning: Clean the radio with a soft, dry cloth. Do not use liquid cleaners, solvents, or abrasive materials, as these can damage the wooden enclosure and electronic components.
• Battery Care: If the radio will not be used for an extended period, remove the batteries to prevent potential leakage and damage.
• Storage: Store the radio in a cool, dry place, away from direct sunlight, high humidity, and extreme temperatures.
