Voice Operation
Precaution
If words are spoken other than names, or words are used that this product cannot
recognize, it could make mistaken recognition, so exercise caution. Also, if this product
is used while driving, be sure to close the car windows.
In order to enable this product to recognize the voice command (name), the name needs
to be voice-recorded in this product in advance.
Record the name in a place which is as quiet as possible.
If the name you want to record is long, we recommend that you shorten it by saying it
fast.
Avoid recording the same or similar sounding words as this may result in incorrect
operation.
Voice Guidance for this product is provided in 4 languages, English, French, German
and Dutch. Select the desired Voice Guidance language. (Refer to “Selecting the Voice
Guidance Mode” on page 18.)
Voice Guidance can be turned OFF. In this case, proceed with each operation according
to the confirming beeps.
During voice recording operation, do not perform any operation of the Head unit.
Otherwise, previously-recorded contents may be deleted.
During Head unit operation, voice recording operation may be disabled.
This product performs a self check for 6 to 10 seconds after the ignition key is turned to
the ACC (Accessory) position, during which time it does not operate.
