Brighten. To brighten the display press LAMP;
release for 2 to 6 seconds; press and hold LAMP.
All lamps light and the intensity slowly increases.
At full brilliance, ALARM DS3 sounds. Release
LAMP when desired intensity is reached. The
display returns to previous indication at the new
intensity.
Lamps Test. Set display to full brilliance and hold
LAMP. Observe that all status indicators light, all
data display segments and punctuation light,
ALARM DS3 sounds, and computer, power supply,
and CDU fault indicators turn white. Release
LAMP and note that display returns to previous
indication ALARM DS3 turns off, and fault
indicators turn black.
Data Entry/Display.
NOTE
Successful completion of the test requires
entry of the following survey parameters:
Spheroid
Vehicle
UTM Zone
Easting (±100 meters)
Northing (±100 meters)
Elevation (± 10 meters)
Erroneous entry of these parameters, except vehicle, may
result in an IMU failure indication.
a. Certain data is required to be entered by the opera-
tor. The operator must have a specific knowledge of the
PADS requirements and the program in use. Certain
inputs are cued by a flashing display; generally related to
a specific CDU pushbutton which must be pressed
followed by a numeric entry. Other inputs will be dis-
played on a non-flashing CDU display, and will merely
require the operator to press ENT,
signifying the opera-
tor concurs with that data.
b. The operator recognizes a cue by pressing the
pushbutton corresponding to the flashing symbol. The
displayed symbol stops flashing and the zero(s) go blank.
Enter data with the numeric pushbuttons. Each numeral
enters the display at the extreme right and moves one
space to the left when a new digit is entered.
c. If a wrong number is entered press CLR to clear
the display. When all numbers are entered check that
the data is entered correctly. If possible, use a second
person to check the entry. Press ENT
to enter the data
into the system. The display will show a new message.
d. The PADS is programmed to survey in any of the
following spheroids.
Refer to spheroid numbers and
specific memory type as follows:

For SPH entries to operate in geographic coor-
dinate system, refer to TM 5-6675-308-12/TM
08837A-12/l.
e. At turn on, PADS displays GPS C-E for the solid
state memory. Press CLR to bypass the GPS mode. From
this point the CDU displays cueing that is basically the same
for the initialization phase of operation. “SPH followed by
the number of the last spheroid used (and saved for the solid
state) is displayed. Refer to the preceding paragraph for the
spheroid number versus spheroid in use. The user will then
press SPH and the desired spheroid number, then press ENT
The display then cues for vehicle immediately with core
memory and after a 15 to 20 second PAUSE with the solid
state memory.
e.1. The PADS program contains seven standard U.S.
Army vehicles and has the capability of having the
operator add lever arm information for up to three
nondefined vehicles. The standard vehicles in the order
of selection and CDU display follow. The program will
display the last vehicle entered during the initialization,
i.e., if the OH-58 had been selected before the system
was turned off, the CDU at turnon would indicate OH–58 5.
