Symptom

Remedy

Displays “COMMAND NOT
RECOGNIZED” or the sys-
tem does not interpret the
command correctly.

1. Ensure that the command is valid, see Command list (Refer to Owner’s Manual).

2. Ensure that the command is given after the tone while “ LISTENING” is displayed.

3. Speak clearly without pausing between words and at a level appropriate to the ambient noise level.

4. Ensure that the ambient noise level is not excessive, for example, windows open or defrost on.

NOTE:
If it is too noisy to use the microphone, it is likely that voice commands will not be recognized.

5. If optional words of the command have been omitted, then the command should be tried with these in

place.

6. If a number of commands have been given in rapid succession resulting in the message “COMMAND

NOT RECOGNIZED” to be displayed, then allow the system to recover (approximately one minute)
before trying the command again.

7. If the system consistently does not recognize commands, the voice training procedure should be car-

ried out to improve the recognition response for the speaker.

Displays “NO SPEECH
DETECTED”.

1. Ensure that the command is given after the tone while “LISTENING” is displayed.

2. Ensure that the command is given within a maximum of five seconds from the end of the tone.

NOTE:
Be sure you know what to say before pressing the Voice button.

Displays “NAMETAG NOT
UNIQUE”.

1. This response will be received when storing a nametag if the nametag being given has already been

stored. This can be confirmed by giving the Radio Directory command.

2. If this response is received and the nametag has not been used already, then it is too similar to an

existing nametag or voice grammar and an alternative should be used.

The system consistently
selects the wrong nametag.

1. Ensure that the nametag requested matches what was originally stored. This can be confirmed by

giving the Radio Directory command.

2. Delete one of the nametags being confused and replace it with a different nametag.
