2.5.1
Initial Start Up
Typically, new units are shipped from the factory with the Transmit Carrier set to OFF.
CAUTION
Protect existing communication traffic. Before you connect power and start the unit,
disconnect the transmit output from the operating ground station equipment.
Disconnect the transmit output from the operating ground station equipment before starting the
unit for the first time. Starting the unit with incorrect settings could disrupt the existing
communications traffic.
At the rear of the unit, set the power switch to ON. The unit does a diagnostic test each time it is
started. If the diagnostic test finds a failure, the Fault LED comes on.
Do the initial configuration check using the front panel or the terminal mode.
The terminal mode shows a full screen of all of the configuration settings. However, you must
have a separate terminal or computer and software to use the terminal mode. Start the terminal
mode using the front panel to go to the System M&C submenus.
