Function
Control, indicator, or connector
UPDT
Initiates position and/or elevation update procedure. Lights
UPDT indicator. Pressing UPDT twice cancels a position
and/or elevation update procedure
If system is off, pressing ON/OFF applies power. If system is
ON/OFF
on, pressing ON/OFF causes display to read OFF C-E.
Pressing ENT turns system off. Pressing CLR continues
operation
LAMP
Tests all CDU status indicators, alphanumeric data display
lamps, and system fault indicators. When held down, varies
lamp intensities and when at full brilliance, sounds ALARM
DS3
MON
Selects monitor mode; lights MON indicator
ADZ
Directs system to enter or display adjacent UTM grid zones;
lights ADZ indicator
SPH
Allows entry and display of earth spheroid number used in
data reduction
TIME
During initialization and zero-velocity correction, displays
elapsed time since turn on. When vehicle is in motion
displays time-to-go to the next zero-velocity correction.
Silences ALARM DS3 for 30 seconds
ID
When pressed, followed by an ID number, followed by ENT,
cues PADS to provide requested mark data identified by
that ID number. ID, O, ENT indicates current data display.
Pressing ID twice selects display of position, azimuth and
elevation (PAE) display
Allows entry and display of distance between porro prism and
DIST
theodolite for an optical position mark. Displays distance
between the points on a two-position azimuth mark
Allows entry (at an optical position and azimuth mark) and
display of horizontal angle measured by theodolite
E
Allows entry and display of UTM grid zone and casting
N
Allows entry and display of northing; when pressed twice,
indicates southern hemisphere by displaying S. Only during
the initial entry of data (before entering northing) may the
change in selection of hemisphere from northern to southern
be made
EL
Allows entry and display of elevation
GAZ/TAZ
Displays grid azimuth. When pressed twice, displays true
azimuth, clear or enter (TA C-E). Operator may display
true (geodetic) azimuth by pressing ENT. If CLR is pressed,
grid azimuth is displayed
1, 2, 3, 4, 5, 6, 7,
Enters numerical data as selected
8, 9, 0
+ 2 , 8
When elevation has been selected for entry of data, the first
pressing of the 2 or 8 will enter a + or , respectively;
thereafter, the 2 and 8 revert to normal number functions.
Advances (+) and decreases () ID and monitor numbers
