System Test Mode - Sega TETRIS GIANT Owner's Manual

9-2 SYSTEM TEST MODE

● The details of changes to TEST MODE settings are saved when you exit from
TEST MODE by selecting EXIT from the SYSTEM TEST MODE menu. Be careful
because if the power is turned off before that point, changes to the settings will
be lost.
● Executing BACKUP DATA CLEAR in the SYSTEM TEST MODE does not clear the
BOOKKEEPING data in the GAME TEST MODE.
● Use with the specified settings. If settings other than those specified are used,
inappropriate operations or malfunction may occur.
SYSTEM TEST MODE is used mainly to check that the IC board is operating normally and to change the coin/
credit settings and the game settings.
