4.0 ANNUNCIATOR CONFIGURATION
4.1 The DD-40NTS series unit MUST be configured prior to use. If replacing an older series DD
series annunciator, modes 1 and 4 can be used to directly emulate the older system’s
performance. Mode 1 duplicates the operation of the DD-40 series and mode 4 duplicates
the DD-20 series units. To configure the unit, press the MENU key to reach the configuration
headings from the normal display mode. After a selection has been made, press the ENTER
key to save the selection. Press MENU to move to the next step. A flowchart is provided that
shows step-by-step progression through the annunciator configuration procedure.
4.2 CONFIGURE MODE - The mode selection allows the unit to be programmed in one of four
modes as shown. The RESET button must be pressed after a change in mode number.
NOTE: A keypad sequence (password) is required to edit values. From the status screen
(RPM, HOURS, or STATUS) , press and hold down the ENTER key then press the MENU key
at the same time to allow values to be modified. Otherwise, selected items may only be
viewed. There is no similar protection for the TIMER button (Class B1 and B2 timers) or
hourmeter.
