Preface
P
This manual provides installation and operation information for the Radyne DMD20/DMD20 LBST
Universal Satellite Modem. This is a technical document intended for use by engineers,
technicians, and operators responsible for the operation and maintenance of the DMD20/DMD20
LBST.
Conventions
Whenever the information within this manual instructs the operator to press a pushbutton switch
or keypad key on the Front Panel, the pushbutton or key label will be shown enclosed in "less
than" (<) and "greater than" (>) brackets. For example, the Reset Alarms Pushbutton will be
shown as <RESET ALARMS>, while a command that calls for the entry of a ‘7’ followed by
‘ENTER’ Key will be represented as <7,ENTER>.
