3. Operating Instructions

3.1 Power On/Off

To switch between different video input sources (HDMI, VGA, AV, BNC), press the 'KEY' button on the back of the monitor. Repeated presses will cycle through the available inputs.

3.3 Brightness Adjustment

4. Maintenance

4.1 Cleaning the Monitor

• Screen: Gently wipe the screen with a soft, lint-free cloth. For stubborn marks, slightly dampen the cloth with water or a screen-cleaning solution. Avoid harsh chemicals or abrasive materials.
• Exterior: Clean the monitor's casing with a soft, dry cloth.

Caution: Always disconnect the monitor from the power source before cleaning.

4.2 Storage

When not in use for extended periods, store the monitor in a cool, dry place, away from direct sunlight and extreme temperatures. If possible, use the original packaging for protection.

5. Troubleshooting

If you encounter issues with your JUN-ELECTRON Mini Monitor, refer to the following common solutions:

• No Display:
  • Ensure the power adapter is securely connected and the monitor is powered on.
  • Verify that the video cable (HDMI, VGA, AV, BNC) is correctly connected to both the monitor and the source device.
  • Confirm the correct input source is selected on the monitor using the 'KEY' button.
  • Test with a different video cable or source device if possible.
• No Sound:
  • Check the volume settings on both the monitor and the connected source device.
  • Ensure the audio is being transmitted through the selected video input (e.g., HDMI carries audio, VGA typically does not without a separate audio cable).
• Poor Image Quality:
  • Ensure the source device's resolution output matches the monitor's native resolution (1024x600).
  • Check for any damage to the video cable.
  • Adjust brightness and contrast settings via the monitor's controls.
• Monitor Not Turning On:
  • Verify the power adapter is functional and the power outlet is active.
  • If using Micro-USB, ensure the power bank or adapter provides sufficient 5V/2A output.
