Regardless of which relay is chosen to be adjusted, the next screen to appear on the LCD is
the following;

                    DELAY  =  0.500S
                    INC     DEC     OK

The delay period can now be incremented in 10 millisecond steps by pressing the 

INC

 button.

The maximum delay is 2.000 seconds. Conversely, the delay period can be decremented in 10
millisecond steps by pressing the 

DEC

 button.  The minimum delay is 0.000 seconds.  When

the delay is set to the desired period, pressing the 

OK

 button will bring the user back to the

previous screen, where the other relay may be selected for adjustment or the 

OK

 button can be

pressed and testing may begin. When the 

INC

 or 

DEC

 button is pressed and held, the delay

value will change at a moderate rate for the first five values and then change at a much faster
rate until the button is released.

In this mode of operation Relay 3 is not used.

Pressing the Quit button will cause the unit to exit this mode and return to the main
configuration selection screen.

Non-latching/Non-sequential Mode

When in this mode of operation any trigger input from either microphone will cause it's
corresponding relay to close for the time determined by the delay period.

The same testing screen as for the Non-latching/Sequential Mode is displayed and the
selection menu responds in the same manner.
