General Operation
3/21/96
All SCDU functions have at least 2 levels and some functions use 3 levels. The
data indicator below the lower left corner of the 4-1/2 digit display is used to
indicate which level of a particular function the SCDU is currently at. The top
level of the SCDU operation is called the "Function" level. The data indicator is
off when the SCDU is in the "Function" level. The
⇑
or
⇓
keys are used to select
a function number to be accessed while at this level. The
⇑
key increments the
function number in the display while the
⇓
key decrements it. The SCDU will
ramp the displayed function number when the
⇑
or
⇓
key is pressed and held for
1/2 second or longer.
The DATA/FCTN key is used to toggle between the “Data” level and the
“Function” level. Press the DATA/FCTN key when the desired function
number is in the display. At this point, the SCDU leaves the "Function" level
and enters the "Data" level. Note that the data indicator is now GREEN. This
operation is consistent for every function on the SCDU, although the data
actually displayed while the indicator is GREEN is function-number specific.
Examples of every type of SCDU function are given in subsequent sections. All
function numbers are the same for both the SCDU and the PCDU (Portable
Control/Display Unit). (See the “PCDU Guide” for steps required for PCDU
function entry.) There are some functions, however, that can only be performed
with the PCDU. When such a function number is selected on the SCDU and the
DATA/FCTN key is pressed, the SCDU’s display will change to:
