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.

• Speak conversationally.

• 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.
