Operating Instructions
The Valor-USBc microphone is designed for intuitive use with Push-to-Talk (PTT) applications.
- Front-Facing PTT Button: The large speaker grille on the front of the microphone also functions as a PTT button. Press this area to activate the PTT function within your compatible application. This is particularly useful when wearing gloves.
- Tactile Thumb PTT Button: A dedicated tactile PTT button is located on the side of the microphone, offering an alternative activation point. This button features two internal switches for enhanced reliability.
- Earpiece Usage: If a listen-only earpiece is connected to either 3.5mm port, audio will be routed through the earpiece instead of the integrated speaker.
- App Compatibility: The Valor-USBc is compatible with various PTT applications. Refer to the compatibility chart below for specific application support on Android and iOS devices.

Maintenance
To ensure the longevity and optimal performance of your Valor-USBc microphone, follow these maintenance guidelines:
- Cleaning: Wipe the microphone's exterior with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners.
- Cable Care: The coiled cable is reinforced with Kevlar for durability. Avoid excessive pulling or sharp bending of the cable, especially at connection points, to prevent strain.
- Storage: Store the microphone in a dry, cool place away from direct sunlight and extreme temperatures when not in use.
Troubleshooting
- No Audio/Microphone Function:
- Ensure the USB-C connector is fully inserted into your device.
- Verify that your PTT application is correctly configured to use the external microphone.
- Check your device's audio settings to ensure the external audio device is recognized.
- Intermittent Connection:
- If using a thick phone case, a USB-C extender may be required to ensure a secure connection.
- Inspect the USB-C port on your device and the microphone for any debris or damage.
- Earpiece Not Working:
- Ensure the earpiece is fully inserted into one of the 3.5mm locking ports.
- Test the earpiece with another audio source to confirm it is functional.
