Break
In most cases this key will abort a command
and return the user to the main menu for the
next programming sequence without any new
information being stored. When in the main
menu, pressing will return the system to the
normal scan mode.
Enter
Enters numerical inputs into the memory and
moves to the next program stage, or at the
end of a program sequence; to the main
menu ready for the next program.
When programming is completed, the system returns to its
normal scanning mode and, until the correct password is
entered, the keyboard has no influence on the processor,
thus guarding the system from unauthorized tampering.
The unit is mounted in the rack units' front panel, which
may be flipped up, locking automatically in a horizontal
position. This is an ideal angle from which to view and
operate the unit.
