Voice Command Guidelines
NOTE:
If a voice command is uninterpretable, verify the system is
performing the intended action or displaying the desired data. If the system
does not recognize a command, use the touchscreen to execute the function.
The GTN Voice Command History details all commands performed.
• Position the headset MIC approximately 1/8-inch from mouth, align with
bottom lip to avoid breath sounds in the microphone.

• Enunciate.
• Speak in a normal tone and volume.
• Speak at a normal cadence (not too quickly or slowly).
• Pause briefly between activation of the PTC switch and when speaking the
voice command.
• Review the commands prior to performing the qualification.
