Once you have made all your selections, press CLEAR to return to your game. When the computer is first powered on, certain default options are set. Options which are automatically in effect at the first startup are shown in the chart with a plus, and options which are off are shown with a minus. Whenever you reset the computer for a new game, most of your selected options are carried over to your next game.

For Operation Mode and Rotating Display Mode options, the BLACK/> and </WHITE keys are used to cycle through the options within each group. For each option, a plus (+) in the display indicates the option is ON, and a minus (­) means the option is OFF. For Bronstein Clock Options, press ENTER to cycle through the different clock options. The clock option you choose to display will be the selected time control when you exit Option Mode.
