menu tree and select the parameter to be set. After arriving at a parameter that needs to be
modified, depress <ENTER>. The first space of the modifiable parameter highlights (blinks) and
is ready for a new parameter to be entered. After entering the new parameter using the keypad
(Refer to Figure 4-3), depress <ENTER> to lock in the new parameter. If a change needs to be
made prior to pressing <ENTER>, depress <CLEAR> and the display defaults back to the
original parameter. Depress <ENTER> again and re-enter the new parameters followed by
<ENTER>.
Following a valid input, the DM240XR will place the new setting into the nonvolatile SRAM
making it available immediately and available the next time the unit is powered-up.
