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 dis-
appear. 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.
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 dou-
bles as an "Enter" key, once numbers are entered, and when the cursor is
moved to it's 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.
