FAQ

Q. I can't access the Windows start menu or task bar to attempt to debug a
problem.
A. Refer section 1 to connect a keyboard and mouse to the console and section 2
to close the Tango software applications. The Tango applications are set to
always stay on top so you need to close them to see the Windows desktop or
start menu.
Q. My console gets false touches when I am not touching the screen.
A. Your touchscreen may be dirty. Check for foreign particles in the area where
the touch is detected (look for the cursor). In particular, small drops of
moisture may cause false touches.
Q. When I touch the screen, the cursor does not move to my finger accurately.
A. Your touchscreen needs to be re-calibrated (see section 23).
Q. My console does not detect my finger when I touch the screen.
A. There is a problem with your touchscreen. Follow the procedure to clean the
screen and bezel area. Check that the touchscreen driver is enabled and
configured correctly (see section 4). Alternately you may need to check the
touchscreen hardware connections (see section 12). There is a status LED
(visible inside the console) which will help you identify the problem.
Q. My console's LCD is blank.
A. If the "Console Starting. Please Wait....." message is displayed on start-up
(see section 6) then the problem is most likely with the windows display
settings. Try pressing Cntrl + Alt + F3 and after a few seconds the display
should come back. Follow the steps in section 3 to re-set the correct graphics
settings. If the display is blank at start-up then you most likely have a
hardware fault (or possibly a BIOS fault which would be rare unless you have
fiddled with the BIOS settings). Refer to section 11 to check the display
hardware.
Q. My console does not appear to power up.
A. It is possible that the PSU to one or all sections of the console has failed. This
will be most obvious by a lack of illumination of the LCD backlight on power-
up. Check the external PSU is connected to the console and to the mains.
Make sure the power switch on the external PSU is in the ON position.
Otherwise, see section 19 for details of potential PSU problems. Section 24
details the various stages of start-up which may also be useful in determining
why your console does not power up.
