7.1.5. Status LEDs

There are four Status LED's on the front panel to the right of the concentration
display. These LED's provide a quick view of the instrument's Status as well as an
indication of any problems that may exist. The normal state for these LED's after
the initial 20 minute warm-up period is as follows:
If any of these LED's are in a different state than shown above, then some
adjustment or troubleshooting should be performed. See Section 10.1 for more
detailed information.

Front Panel Menus

The 465L has an interactive menu structure that can be operated from the front
panel. From within this menu structure, the operator can view real-time parameters
such as temperature and pressure, view configuration information, and edit setup
parameters such as alarm limits.
Figure 7-2 below shows the menu structure as well as the buttons that are used to
navigate it.
Starting with the display in Concentration mode, press CFG to enter Menu mode.
At this point the unit-of-measure LED should turn off and the first level of the Menu
tree will be active. Pressing the UP/DOWN arrows will now select from the items
available at this menu level. Press ENT to enter one of these sub-menus or press
CFG to back out of this menu level back to Concentration mode.

ENT will exit the Menu mode and return the display to Concentration mode.
4. The Menu mode will timeout if no buttons are pressed within 30 seconds, and
