Bracket Mode Screens
The easiest way to make sure the Mega 350/450 is in Bracket mode is to press the Bracket key (BRKT). When in
Bracket mode the Mega 350 LCD will display seven different screens and the Mega 450 will display eight different screens.
The different screens broken into four types. The first type of screen is the Bracket screen this is the main screen. The second
type of screen is the Set Up screen. There are five different Set Up screens. The last two types are the Drivers Reaction Tester
and the Mega 450’s Replay Tach. The Drivers Reaction Tester and the Mega 450’s Replay Tach screens are the only screens
shared between Bracket mode and Pro mode. This means that the Drivers Reaction Tester will function the same in either
mode and the Mega 450’s Replay Tach will display the same information in either mode. See page 18 for more information.
There are four lines of information shown on the Bracket screen and all the Set Up screens. The information
displayed for each screen along with the screen number or the location of each screen is shown below.

* Will only display value if S.F.O. is set to corresponding mode.
** Will only be displayed if S.F.O. is set to mode 2 *** Will only be displayed if engine is off.
The main way to move from screen to screen is to use the Set Up key. If the Mega 350/450 is displaying screen 3,
which has the SLE, PTSO, Timer 1, and Timer 2 information and the Set Up key is pressed and released the Mega 350/450
will now display screen 4, which has the first four stage timer settings. By repeatedly pressing the Set Up key the Mega
350/450 will cycle through screens two through eight. If the S.F.O. mode is not set to 2 to enable the second 4 Stage Timer,
screen 5 will be skipped as the screens are cycled through. However all settings for screen 5 will still be stored in memory and
will reappear when the second four stage timer is turned on again. If the Mega 350 is displaying screen seven, or if the Mega
450 is displaying screen eight and the Set Up key is pressed and released the Mega 350/450 will go back to screen two. To get
back to screen one (Bracket screen) use the BRKT key. This can be done from any screen including the Pro screen.
When viewing any of the first six screens there will be a set of arrows on the right side of the LCD. These selection
arrows point to the selected line on the screen. There will only be one selected line on the screen at a time. With the one
exception, that being when changing the Shift Point on screen six. Once a line has been selected the setting or value for that
line can be changed. To change the selected line, press and release the Next key. The selection arrows will move to the next
line on the screen. If the line selected is at the bottom of the screen the selection arrows will return to the top of the screen
when the Next key is pressed and released again.
Screen 1 -- Setting Dial-In or Delay Times
To enter a new Dial-In or Delay time the Mega 350/450 must first be displaying the Bracket screen. If the Bracket
screen is not being displayed press and release the BRKT key. When the Bracket screen is first displayed the selection arrows
will be on line 1 (Your Dial-in). This means that line 1 is selected, to change which line is selected use the Next key. Once
the desired line has been selected press and released the Clear key the selected display line will now be blank indicating the
unit is ready to accept the new time. Now using numerical keys enter the new time, leading zeros do not have to be entered.
For example if 9.90 for a Dial-In time were desired 990 would be entered on the keypad. If less than four digits are entered for
a time, pressing the Next key will act as an enter key and the leading zeros will displayed on the LCD. As the numbers are
entered they are shown on the display, indicating the numbers are accepted and entered into memory. If a mistake is made
while entering the time, press and release the Clear key and reenter the time again.
The Scrolling Arrow keys can also be used to change a Dial-in or Delay time. First make sure that the selection
arrows are on the line to be changed. If not, change which line is selected using the Next key. Once the desired line has been
selected pressing and releasing the Up Arrow key will cause the time to increase by one. While pressing and releasing the
Down Arrow key will cause the time to decrease by one. If the Up Arrow key is held down the time will scroll up and if the
Down Arrow key is held down the time will scroll down.
