• Microphone Not Transmitting:
  • Ensure the PTT button is being pressed firmly during transmission.

• Verify Compatibility: Before purchase or use, always double-check the 2-pin connector type (Kenwood or Motorola) required by your specific walkie-talkie model to ensure proper function.
• Optimal Microphone Placement: For the clearest transmission, ensure the microphone is positioned directly in front of your mouth, about 1-2 inches away.
• Volume Adjustment for Environment: Utilize the headset's volume knob to adapt to varying noise levels. Increase volume in very noisy settings like ball games or racing events, and decrease it in quieter environments like churches or theaters.
