TROUBLESHOOTING GUIDE
The system should respond correctly to all voice
commands without difficulty. If problems are en-
countered, follow the solutions given in this guide
for the appropriate error. Where the solutions are
listed by number, try each solution in turn, starting
with number one, until the problem is resolved.
Symptom/error message Solution
The system responds “Command Not
Recognized” or the system fails to rec-
ognize 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.
