SECTION 3: DP-3 OPERATION-CROWN FMX DMS
FRONT PANEL
SUMMARY OF FUNCTIONS:
This section provides general operating parameters of your transmitter and a detailed
description of its front panel display and controls.
If you are working with a Crown FMX 30, 100, OR 250, the range of control options
from the front panel is much greater than with the FMA Series, and you may still use
your PC for more in depth control.
The user interface consists of a front panel-mounted jog-wheel, (which also operates as a
selector button), and an VFD screen. The VFD screen displays menus and parameter
settings.
The menus are used during initial setup and for adjusting the processing parameters.
Rotating the Jog-Wheel moves a selector arrow up or down through menus and parameter
choices. Pressing the jog-wheel (called “clicking”) selects the indicated menu item or
parameter choice. When editing the parameter values, rotating the jog-wheel adjusts the
parameter’s value up (by rotating CW) or down (CCW). Once the desired value is
reached, clicking the jog-wheel saves the value and returns the display to the previous
menu or sub-menu. Thus pressing or clicking the jog-wheel serves as, depending upon
the VFD screen, an Enter or Select command.
3.1 Initial Power-up Procedures
