7. Troubleshooting

• Difficulty Connecting to Wi-Fi:
  Ensure you are connecting to a 2.4 GHz network. Entering complex Wi-Fi passwords can be challenging due to the interface; use the numerical keypad for digits and carefully navigate character selection. Try simplifying your Wi-Fi password temporarily if possible for initial setup.
• Poor FM/AM/SW Reception:
  Fully extend the external antenna. Try repositioning the radio. For AM, screen interference can occur; try blanking the screen with the power button or allowing the screen to time out for clearer reception. Consider connecting a specialized external antenna for specific bands.
• Intercom (Walkie-Talkie) Not Transmitting:
  Ensure the screen is active before pressing the Push-to-Talk (PTT) button. The intercom function might be inadvertently turned off or require re-activation via the '0' button.
• Rapid Battery Drain:
  The intercom function, especially when running in the background, can consume significant battery power. Turn off the intercom when not in active use.
• Voice Search Not Working as Expected:
  Ensure a stable internet connection. Speak clearly and directly into the radio's microphone. The system may require specific phrasing; try different commands.
• Favorite Stations Not Saving:
  Verify that the bookmarking process was completed correctly. If the issue persists, check for available firmware updates, as this may be a software-related issue.
