NOTE: The last status of a unit is retained even when power is removed. When power is restored, the unit will
return to it's previous settings.
When power is first applied, the unit will read and display the internal network device’s IP address if any
ethernet options are installed. The model number and current firmware version will then be displayed for
approximately 2 seconds. See figure 2.4 for display formats.
The unit is now operational and ready for any changes the operator may desire. The main display is formatted
such that the first column displays the current drawn by each unit and the second column displays the
attenuation setting for each channel.
