Press Menu
Key The status displays consist of seven pages with the following information:
· Self-test results
· Reset battery usage time
· Access input/output (I/O) information
· Check on satellite search/tracking information
· Satellite signal/health conditions
· Special satellite information
· Self-test messages
You can access the status displays on the first page of the system’s MENU.
After activating the STATUS field, scroll through the various pages by using the UP and DOWN arrow key.
Note: Though there are seven pages to the status displays, the page that shows the satellite ID number, health, azimuth, and elevation angle may have additional subpages to accommodate all visible satellites.
System Status
Page This page contains system information. The system status page has four lines of information as shown in the diagram, and the display line number is described in the table below:
Line Display Information
1 GPS Status Displays good or <3SV; must track four satellites in order to give accurate positioning
2 Self-Test
Results Displays Self-test OK or Self-test Fail 3 Antenna
Source
Shows Internal antenna or External antenna as determined by the user configuration
4 Power Source Shows Battery or Vehicle power

ContinuedBattery Status
Page The information on this page shows the type of battery system being used to power the unit and how much life is left in the battery, depending upon the type of battery and the accurate entry of the time used. This page has four lines of information as shown in the diagram, and the display line number is described in the table below:
Line Display Information 1 Battery
Selection
The user must activate this field to input the battery type used. Either BA-5800/U or AA alkaline. The unit will automatically sense and display Ni-Cad if a nickel-cadmium battery has been installed.
2 Battery Type The unit will automatically display the battery nomenclature that was selected from the
information in line 1, either rechargeable or non-rechargeable.
3 Time Used This is the amount of time the battery has used.
4 Time Left This is the calculated amount of battery life remaining, according to the information on line 3.

ContinuedI/O Status Page The I/O (input/output) page provides information for input/output data for the PLGR. The operator will not normally utilize this information; however, line 4 allows the user to identify the intensity level of the backlight when
backlighting is in use. The higher the intesity level, the more battery life is consumed. This page has four lines of information as shown in the diagram, and the display line number is described in the table below:
Line Information 1 Displays one of the following:
· None—input is not being received.
· Active—input is being received.
· Using—input is being received and is being used.
Note: Differential GPS is the GPS correction transmitted from the reference station to mathematically correct for position errors.
2 Displays either none or active 3 Displays either none or active
4 Displays either on or off and a percent of maximum brightness

Tracking Status Page
This page will initially display the status of four of the five satellites that the PLGR is trying to track or is tracking. To display the status of the fifth satellite, press the RIGHT arrow key. This page has four lines of information as shown in the diagram, and the display line number is described in the table below:
Line Information 1 The number assigned to the satellites that are currently being
tracked or searched for.
2 The strength of the signal being transmitted from the satellite—25 to 50 dB (decibel) are good, 34 dB is the best.
3 The code of the signal being transmitted. There are three codes:
· CA—course acquisition
· P—encrypted signal transmitted by GPS satellites
· Y—encrypted signal transmitted by GPS signals that must be decrypted by the PLGR
4 There are four codes that represents the satellite status:
· I—interference
· R—recovery
· S—searching
· T—tracking

Status Page Depending on the number of visible satellites, there may be subsequent pages for this display. To access the subsequent pages, press the DOWN key, there are enough continuous pages to include all information for all visible
satellites. This page has four lines of information as shown in the diagram, and the display line number is described in the table below:
Line Information 1 Displays the ID numbers assigned to specific visible satellites
2 Shows the health of each satellite identified on line 1 as OK or Bad 3 Displays the azimuth of each satellite—given in degrees—relative
to true north
4 Shows the elevation angle of each satellite and whether it is ascending or descending by the direction of the corresponding arrow

Message Page This page is an encrypted message from the satellite control center—if one has been sent. This message is only readable by personnel with the ability to decrypt the message. This page has three lines of information as shown in the diagram, and the display line number is described in the table below:
Line Information 1 Displays the satellite ID number for which special messages are
available
2 Displays messages from satellite and can contain alphanumeric symbol or special symbols, such as a dash or quotation mark 3 Same as line 2

Message The final status display page contains the results of the self-test. More than one message may be displayed. This page has four lines of information as shown in the diagram, and the display line number is described in the table below:
Line Information 1 Displays either the device that failed or the device on which
information is available
2 Displays type of information that shows either failure or the information
3 Displays the temporary (t) and permanent (p) codes for the data displayed
4 Clears the temporary and permanent codes on line 3
Setting Up
Menu Press the MENU key to activate the SETUP field. The setup screen allows the user to set operating parameters for the PLGR according to their
requirements. Once selected, the setup screen has seven pages. To access the additional four pages, you need the new software version. Make sure a double arrow (ô) is displayed in the lower right-hand corner and press the DOWN arrow key.
Set Up Mode
Page This page has two lines to determine power consumption and satellite signal selection. Line 1 is mode description information. Line 2, SV TYPE, the user can program the PLGR to receive either mixed for all satellite signals or Y for encrypted signals. The unit must have crypto variables loaded or the unit will only receive mixed signals. This page has two lines of information as shown in the diagram, and the display line number is described in the table below:
Line Display Information 1 Continuous
POS and VEL Update
Shows the current operating mode and provides continuous position updates to the user
2 SV-TYPE Displays the type of satellites that the PLGR will track.
