In order to unlock the display, input a "Z" pattern. First, push the top left (gray)
arrow, then the top right, followed by the bottom left and finally the bottom
right. The "LK" notation in the upper right corner of the display will now
disappear. Push the gray arrow at the top left hand corner once more to enter
into the menu structure. Once one moves deeper into the menu structure,
additional time is provided to the user so that the lockout initiation does not
become a nuisance. This additional "revert" time is defaulted at one hour and
is also user configurable.
NOTE
Always clean dust and soil away from the LOI screen each time the LOI is
used. Excessive dust can prevent the LOI from entering lockout. This
condition can cause uncommanded operations to occur.
LOI KEY DESIGNATIONS
The gray key (top left) will move one level higher in the menu structure. When
entering numbers, this key will move the cursor to the left. This key also
doubles as an "Enter" key, once numbers are entered, and when the cursor is
moved to its left-most position. The new data entry value will appear in the top
line of the LOI display once it is accepted.
The blue key (bottom left) acts as a selector when choosing from among a
number of menu items. This key also will move the cursor to the right when
entering numbers.
Up/Down keys (to the left side of the keypad) are used to increment up and
down when selecting from a series of menu picks. They are also used for
incrementing values up and down for data input.
LOI MENU TREE
This LOI menu for the Oxymitter 5000 is shown in Figure 6-4. This menu tree
is specific to the Oxymitter 5000. The menu tree will assist in navigating the
LOI.
Menu items in normal text display information only. Menu Items in italics
permit data entry. Menu items in bold text are procedures.
