ROVISIONING
The HLU-611 List 1 contains a non-volatile RAM (NVRAM) which stores
the system option settings. The options are set from the buttons on the front
panel, or through the RS-232 interface. They are retained if shelf power is lost
or if the HLU-611 List 1 is unplugged. See page 9 for the HLU-611 List 1
System Options table.
Using the SEL and MODE Front Panel Buttons
To provision the HLU-611 List 1 through the SEL and MODE front-panel
buttons:

Press the MODE button for approximately one second. The message
displayed on the front panel alternates between the first system parameter
and its current setting.
2
Press the SEL button to step the display through all possible settings (one
at a time) of the parameter being displayed.
3
Press the MODE button to select the desired parameter and move to the
next parameter. After you have configured the last parameter, the display
prompts you to confirm the settings.

Do one of the following:
•
Press the SEL button to install the settings.
