current state of the console function to on or off. To do this, you must reboot the 
Qube 3 while holding in the recessed Reset Password button on the back panel of 
the Qube 3. See Figure 1 on page 2. 
To reboot the Qube 3 from the LCD panel, see “Reboot” on page 202. 
When you reboot the Qube 3 in this manner, the LCD screen displays either:

or
