3 Basics of Equalization

Basic operation: Store mode

Once you have created a program you would like to save, press the [STORE] button to enter Store mode. This will cause the Numeric LED Display to blink with the number of the current program.

If you were on a Preset program while editing, you will not be able to store the program until you select one of the 30 User program locations as its destination. To do this, use the [DOWN/UP] buttons. If you press the [UP] button first, you will see the Numeric LED Display jump to User program 30, which is the first available User program location. If you press the [DOWN] button first, you will see the Numeric LED Display jump to User program 59, which is the highest-numbered User program location available. If you were already on a User program when you entered Store mode, then using the [DOWN/UP] buttons will call up the next User program.

Once you are in the User program area inside Store mode, pressing the [DOWN/UP] buttons allows you to choose a program number between 30-59 as the destination for your edited program. Pressing and holding one of these buttons will cause the unit to scroll progressively faster through the available choices. If you're holding the [DOWN] button, when the unit reaches User program 30 it will "wrap" around to number 59 and continue scrolling downward. Pressing and holding the [UP] button will cause the numbers to scroll in the opposite direction, wrapping from program 59 to program 30 and continuing upward.

As in Program mode, there's an even faster way to select the destination program location. If you press and hold the [DOWN] button and then push the [UP] button, the unit will jump to Program 30. If you continue pressing the [UP] button, the DEQ230 will jump forward through the User locations in increments of 10 (40, 50, 30, 40, 50, etc.). Similarly, if you press and hold the [UP] button and then push the [DOWN] button, the unit will jump to Program 30. If you continue pressing the [DOWN] button, the DEQ230 will jump backward through the User locations in increments of 10 (50, 40, 30, 50, 40, 30, etc.).

Once you have chosen the location you want, press the [STORE] button again. This will store the program into the user location you selected.

Remember, if at any time you decide you do not want to save the edited program, simply press the [LINK/EXIT] button to return to Program mode. Your edited program will still be there, as evidenced by the dot on the right side of the Numeric LED Display. The “destination” program will not have been overwritten.
