Symptom/error message Solution
The system responds “Command
Not Recognized” or the system fails
to recognize the command correctly. 1. Ensure that the command format is valid. Use the “List Commands” or “What Can I Say?” command under the “Help” menu.
2. Speak clearly without pausing between words and at a level appropriate to the ambient noise level.
3. Ensure that the ambient noise level is not excessive (for example, with the windows open or the defroster on).
NOTE:
If it is too noisy to use the phone, it is likely that voice commands will not be recognized.
4. If optional words of the command have been omitted, then the command should be tried with these in place.
