• LED Display: Provides real-time decoding of Morse code signals.
• Type-C Port: Used for 5V power input and charging the internal/external 3.7V lithium battery.
• DC Power Input: Accepts DC 7-12V, 500mA power supply.
• Audio Input/Output Jacks: For connecting to your ham radio or other audio sources/sinks.
• Control Buttons: Small buttons on the board for potential mode selection or display adjustments (specific functions may vary or be user-defined in DIY setups).

4. Setup

1. Power Connection:
   • Option 1 (DC Power): Connect a DC 7-12V, 500mA power adapter to the DC power input jack.
   • Option 2 (Type-C USB): Connect a 5V USB power source (e.g., a phone charger or power bank) to the Type-C port.
   • Option 3 (Lithium Battery): If using a 3.7V lithium battery, connect it to the designated battery connector on the board. Ensure correct polarity.
2. Audio Input: Connect the audio output from your ham radio or other CW signal source to one of the 3.5mm audio input jacks on the decoder.
3. Initial Power On: Once power is connected, the LED display should illuminate, indicating the device is ready for operation.

5. Operating Instructions

1. Signal Input: Ensure your ham radio or CW signal source is transmitting Morse code signals to the decoder's audio input.
2. Decoding: The decoder will automatically process the incoming audio signals and display the decoded text on the LED screen.
3. Reading the Display: The LED display provides clear and accurate character-by-character or word-by-word translation of the Morse code. Adjust the audio output level from your radio if the decoding accuracy is low.
4. Adjustments: If available, use the small buttons or potentiometers on the board to fine-tune sensitivity or display settings according to your specific setup and signal conditions.

6. Charging Function

The Vikye CW Decoder includes a charging function for connected 3.7V lithium batteries. To charge:

• Ensure a 3.7V lithium battery is properly connected to the 'BAT' connector on the board.
• Connect a 5V USB power source to the Type-C port. The device will automatically begin charging the connected battery.
• Charging status indicators (if present on the board) will show the charging progress.

7. Maintenance

• Cleaning: Use a soft, dry cloth to clean the device. Do not use liquid cleaners or solvents.
• Storage: Store the decoder in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
• Battery Care: If using a lithium battery, follow standard battery care practices to prolong its lifespan, such as avoiding deep discharge and overcharging.
