Chapter 5: Programming Mode
This chapter describes the programming mode of the DL431 Mic Splitter.
In programming mode the four programming buttons in the control panel are used to 
navigate and select options from a number of menus (see “Menus” on page 16), which 
let you set up the unit and view information.
Menu navigation
The four programming buttons in the control panel have the following functions.
The menu flowchart (see “Menu flowchart (menus 1 to 5)” on page 14 and “Menu 
flowchart (menus 6 and 7)” on page 16) gives an overview of all the menus and their 
options, and shows you how to navigate your way around them. When navigating the 
menus, note that: menus are shown on the left, and each subsequent lower level of 
each menu is to the right; an asterisk * (lower-right corner) means that the option is 
not the currently selected one; and flashing options (far left character) are currently 
selected.
>> To enter/exit programming mode
To enter programming mode from any menu display screen, press the MENU button 
and hold down for approximately two seconds; the default display will change to the 
“Select Menu:” display (see display A on page 14).
To exit programming mode, press MENU repeatedly until you reach the default screen.  
The DL431 Mic Splitter will exit programming mode automatically after about 
20 seconds of inactivity, that is, if none of the programming buttons are pressed within 
that time.
>> To select a menu
In the “Select Menu:” display, scroll to the menu you want by using the up/down arrow 
buttons; its number will flash to show that it is currently selected. Then, press 
SELECT.
