If you find that the Q1 does not respond to your voice commands, try changing the Q1's sensitivity level.
This setting determines how precisely the words that you say need to match the speech patterns that the Q1 has been configured to recognize. You can change it by accessing the Q1's "Settings Menu".
When the level is set to "High" the commands you give the Q1 will need to match the speech pattern it is expecting more exactly, while "Low" is less restrictive and will accept your commands even if they don't precisely match the expected speech pattern.
If you find that the Q1 is not recognizing your voice commands at all, you should change to a lower sensitivity level.
You may wish to switch to a higher sensitivity level if the Q1 often responds to your voice commands by carrying out the wrong command.
