2. Setup and Connection
Follow these steps to correctly connect your audio/video cable:
- Identify Ports: Locate the 3.5mm AV Out port on your Mfine 938, L-938B, or L-938BAM portable radio speaker. Identify the AUX In port on the receiving device (e.g., another speaker, amplifier, or display with AUX input).
- Connect Cable: Insert one end of the Digipartspower 3.5mm AV Out to AUX In cable into the 3.5mm AV Out port of your portable radio speaker.

3. Operating Instructions
Once the cable is connected, follow these general operating guidelines:
- Power On Devices: Turn on both your Mfine portable radio speaker and the receiving device.
- Select Input: On the receiving device, select the appropriate input source (e.g., "AUX," "Line In," or "AV In") to receive the signal from the portable radio speaker. Refer to the receiving device's manual for specific instructions.
- Adjust Volume: Adjust the volume levels on both the portable radio speaker and the receiving device to a comfortable listening level.
- Audio/Video Playback: Begin playing audio or video content on your Mfine portable radio speaker. The signal should now be transmitted to the connected receiving device.
4. Maintenance and Care
Proper care ensures the longevity and performance of your cable:
- Cleaning: Gently wipe the cable and connectors with a soft, dry cloth to remove dust or debris. Avoid using harsh chemicals or abrasive materials.
- Storage: When not in use, coil the cable loosely. Avoid sharp bends or kinks, which can damage the internal wiring. Store in a cool, dry place away from direct sunlight and extreme temperatures.
- Handling: Always grasp the connector ends when plugging or unplugging the cable. Do not pull on the cable itself, as this can strain the connections.
- Ventilation and Humidity: If the cable is used for extended periods, ensure it is in a suitable ventilating and humidity environment. Do not place it on skin products or in areas with excessive heat or moisture.
