The HLU-611 List 3 contains a non-volatile RAM (NVRAM) which stores
the system option settings. The options are set via 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 3 is unplugged. HLU-611 List 3 System Options table on
page 9 lists the system options.
