CONSOLE BIOS

NOTE: Any changes to BIOS settings can be dangerous and may render the
console un-useable. Incorrect display selection in the BIOS will disable the
console LCD and will require considerable disassembly of the console.
The BIOS settings of the console should not require any changes by the user or
during servicing. The selected settings are the default that will remain, even if
the BIOS battery goes flat.
The BIOS start-up messages are hidden from the user and a simple message
stating "Console Starting. Please Wait....." is all that is displayed.
If this "Console Starting. Please Wait....." message is not displayed or the screen
displays a funny pattern or series of lines during boot then there could be a
problem with the BIOS settings (if you suspect they have changed – otherwise
check the display hardware first). You will need to disassemble the console to
access the VGA port inside and then see section 11 for the correct BIOS settings.
7. OPENING THE CONSOLE – UPPER MODULE
WARNING:
The chassis of the Tango console has some flexibility when the top
modules are removed. You must service the console on a flat work
surface and take precautions to ensure the chassis is not excessively
twisted or stressed while disassembled. Failure to take these
precautions could result in damage to some of the internal
components.
The console upper module can be opened for servicing by following the steps
below. Care must be taken to ensure no damage is done to the black painted
surfaces or the acrylic lens material on the top surfaces. Both of these can be
easily scratched if not handled carefully.
• Ensure the console is powered off and all external connections are
removed from the console.
• Remove the aluminium end panels from both sides of the console. This is
done by removing the 6 x M6 CSK screws that secure each end panel.
These screws require a 2.5mm Allen Key for removing them. The location
of these screws is shown below.
