MENU SYSTEM
SYSTEM OVERVIEW
Game variables and diagnostics are presented in a series of on-screen menus. The Main Menu allows you 
to view information, change or verify equipment operation. Submenus display further choices, after which 
more data appears or tests run. Use both operator and player controls to navigate menus and start or stop 
routines.
SCREEN LAYOUT
The color bar at the top center of each screen displays the current menu title. The center of the screen 
holds data (menu items, video signals, statistics, reports, etc.) The bottom of the screen contains messages 
(control functions, revision levels, etc.).
ORGANIZATION
Main Menu screen items are either options or tests. Submenu screen items offer choices within a cate-
gory. A Menu may have zero, one, or several Submenus. You can always return to the previous menu, and 
often advance to the next menu. Detail Menu screen items contain specific information. You interact with 
the system to get results or to make changes.
Use the indicated control to highlight an item. You can only select one highlighted at a time. To return to 
game play, select EXIT TO GAME, then press the indicated button.

You can adjust Attract Mode volume independently of Game volume. Use the joystick to raise or lower 
volume level. Music plays continuously while setting volume.
Use the Player 1 START button to choose Game or Attract volume adjustment. When the selected vari-
able flashes, use the joystick to change the level.
Game volume adjusts from zero to maximum. The game seems more realistic if players experience loud 
sounds during play. These weapons do not have silencers.
Attract volume is continuously adjustable from Mute (zero) to maximum. For greater profits, make 
Attract Mode loud to draw attention to Gauntlet: Dark Legacy Universal Conversion Kit.
You adjust Attract and Game volume levels independently, but Attract cannot be louder than Game vol-
ume. If you try this, Attract level automatically lowers proportionately. Lowering Attract level does not 
affect Game setting.
Volume level is represented a bar made of dots. The longer the bar, the higher the volume. 
Press the Player 2 START button after making volume adjustments. The Player 1 START button cancels 
your recent changes and returns both levels to what they were before you touched them.
NOTE: These adjustments affect both the volume of the tests and game play. If the volume levels are set 
to minimum (zero), there will be no sounds from the speakers during any of the audio tests. Set the volume 
levels to a moderately high value when checking the game audio components and speakers. Return the lev-
els to their previous settings after completing the tests.

Chapter 3 System
The Statistics report allows the operator to assess how well the game is being played. In addition to the 
earnings, various game aspects are tracked to determine the player skill levels.
Statistics may be reset to zero or allowed to increase after each viewing.
The illustration shows how the report screen looks after the game is reset or is first turned on. Most statis-
tics increase in value as the game is played. It is normal for some values to remain at zero: for example, the 
Aux Coins count will not change unless an additional Currency Acceptor has been installed in the game, 
and the Error Count will not change if no errors have occurred.
Low counts in both coin and player statistics may suggest the game is too difficult for the skill levels of 
the players at this location; high continue counts may indicate the game is too easy. Difficulty level and 
other play characteristics may be adjusted from the Game Options menu.
Record statistics before performing service or making repairs on the game.
Press Player 2 START or service credit button to view system errors, which tell you the status of the hard-
ware. Press Player 2 START again, and you will see user messages. Press Player 2 START again and you 
will see histograms. Press Player 2 START again to see level histograms.
Press both START buttons to cancel settings on screen and return all counts to factory default values.
The HISTOGRAMS screens will have no bar graphs until the system has enough data to plot.
The USER MSGS screen will contain no messages until the system detects an error.

These adjustments allow you to customize the game. Each variable changes an aspect of game appear-
ance or play. Optimum settings cause high player interest and increase earnings.

may be reset to factory defaults or changed after each viewing.

The illustration shows how this report screen looks after game is reset or first turned on. Use joystick to 
advance variables through range of choices. Some items have more options than others. View all options 
before selecting one.
The effects of these options can be judged by comparing statistics reports before and after changes were 
made. As players become more familiar with the game, new features or increased difficulty will make the 
game challenging and continue to generate interest.

Medium.
Health Per Credit determines amount of health credits added to the timer each time a player uses a credit 
by pressing the START button. It ranges from 300 to 1000. Factory default is 500.

tings or variables in these tests, which are performed automatically.

uniform from top to bottom and side to side. No retrace lines or noise should be visible.
Borders must be visible on top, bottom, and sides of screen. Image color should not change position or 
color as the background or border are removed or restored from the video display.
Purity tests help verify monitor intensity, black level, blanking and automatic degaussing.
