Drake MQM6000L Multiplexing QAM Modulator - Manual (Page 8)

8 Setup and Programming
Programming and viewing of the various setup and operating parameters is accomplished using the front panel
back lit, two line, sixteen character wide LCD along with the 4 arrow buttons and the eNteR button. the name
of the parameter is on the top line of the display and the setting value is on the bottom line.
to observe a certain parameter setting without intending to change its value, just use the left and right arrow
buttons to navigate through the menus shown in the list. the current setting for each parameter is shown on the
bottom line of the display. Note that depending upon certain settings, some screens are not needed and will be
skipped.
to make a change in the displayed parameter and its setting and if this is the initial setup, you will want to enter the
‘adjust’ mode. to do this, press the eNteR button that is located in the center of the four arrow buttons and hold in
for several seconds until the display begins to flash. After you are in the adjust mode (bottom line of screen flashing)
use the left and right arrows to navigate among screens and use the up and down arrows to change the parameter
setting. When eNteR is pressed, the new settings will be loaded and stored and the unit will exit the ‘adjust’ mode.
you may wish to not press eNteR until you have gone through all screens and settings and then press eNteR to
save and load all changes in one step oR you can store just one or several parameters at a time and reenter adjust
mode to set the next. either method is acceptable.
