4.2 Parameter Setup

The four Cursor Control Arrow Keys are used to navigate the 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 4-2), 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 DMD20 will place the new setting into the nonvolatile EEPROM
making it available immediately and available the next time the unit is powered-up.'
