screen, can be accessed. The Navigator module automatically
returns to the default display mode after 60 seconds of no
keypad activity. Pressing the and keys
simultaneously while the unit displays “Select a menu item”

row keys are used to scroll through the tiered command menu
structure. See the base unit Controls, Start-Up, Operation, and
Service Guide for menu structure. The
key is used to
select a menu item or to accept data entry. The key
is used to exit to the next highest command level (mode) or to
cancel data entry. The sub-mode and item displays will wrap
around with the last and first items separated by a line of dashes
on the display. The ‘>’ symbol is the pointer and is located at
the left side of the display.
At any time, press the key repeatedly as needed
to display “Select a menu item” on the screen. This is the top
level and the arrow keys are used to move the red LED to one
of the 11 desired modes. Press to display the sub-
modes within a top level mode.
Use the arrow keys to move the pointer (‘>’) to the desired
sub-mode. Up to four sub-modes will be displayed on the
Navigator module at one time. Continue pressing the arrow
keys as needed to find the desired sub-mode.
