Set Up Unit
Page This page is used to determine the coordinate system, distance, and angle units. This page has three lines of information as shown in the diagram, and the display line number is described in the table below:
Line First Field Second Field 1 Select MGRS-New option to
coordinate the units. Select the metric field.
2 Select meters or feet—the user must refer to the map to determine the appropriate selection.
Select MSL or DTM; look on the marginal information of your map to make this determination.
3 Select degrees or mils. Select either grid, magnetic, or true to reference North.

Variation Page This page allows the user to enter the magnetic variance for the area that operations are being conducted. This information is found on the map, but the PLGR has the ability to calculate the variance automatically by selecting Calc. This page has two lines of information as shown in the diagram below:

Page This page allows the user to customize the position and waypoint pages. This page has three lines of information as shown in the diagram, and the display line number is described in the table below:
Line Display 1 Select automatic or manual. If less than four satellites are being
tracked or satellite geometry is bad, then select manual and enter the elevation from the map.
2 The time for the GPS is measured from Universal Time Coordinated (UTC/0 degrees longitude):
· Know which time zone you are operating in to input the actual offset time—can obtain from the S-6 section.
· Use the arrow keys to move the cursor to the time line.
· Select the local time offset.
Example: The east coast of the U.S. is –5, therefore you would input: LOC = Z-0500.

Page This page allows the user to select the operating area datum and to control the automatic off timer. This page has three lines of which two lines are
programmable as shown in the diagram, and the display line number is described in the table below:
Line Display Information
1 Datum Name Use the arrow keys to move the cursor to select the datum line and then use the arrow keys to select the appropriate datum.
Datum for the area you are operating in is found in the marginal information of the standard military map.
2 Datum Label Field
This is a display line only and cannot be altered.
3 Automatic Off Timer
According to the last keystroke entered—if the timer is activated—starts the countdown and the unit will power down after the programmed time is reached. The selections are OFF, 15-sec, 5-min, or 20-min.
Data Port Page Input/Output (I/O) options are used in conjunction with data port interface.
Automark The automark mode is used to periodically wake up the PLGR and have it

ContinuedNew Version
Software In order to operate pages 8 through 11, the PLGR must have the new version software. The last four pages that can be viewed with the updated software are listed in the table below:
Page Information Bullseye A common referenced waypoint the user may need to
reference often during the training/mission. Up to two bullseyes may be referenced.
Operator ID Allows an operator identification to be assigned to the PLGR. It may be an actual name, organization, etc. It is not necessary to set up the operator ID for the PLGR to function.
Approach Allows the user to define an extension to the waypoint navigated to during an approach. The approach is used for fixed- and rotary-wing and parachute operations.
Rehearsal Allows the user to modify the tutorial function in order to use a predefined route.
