WE WILL DISCUSS EACH OF THESE MODES.
REMOVE VGT PLGR-16.
VGT PLGR-16
Operating SHOW VGT PLGR-17, Operating Modes, Continued.
Modes,
Continued
IN CONT, OR CONTINUOUS, MODE, THE PLGR COMPUTES YOUR POSITION AND VELOCITY AS IT ACQUIRES AND TRACKS UP TO FIVE SATELLITES. THIS USES THE MOST POWER, AND YOUR PLGR DEFAULTS TO CONT WHEN IT’S CONNECTED TO EXTERNAL POWER. YOU MAY NEED MORE THAN ONE BATTERY FOR A MISSION IF YOU SELECT THIS MODE AND ARE POWERED BY BATTERY ALONE. DURING A COLD START, USE CONT MODE UNTIL THE PLGR:
· ACQUIRES AN ALMANAC;
· OBTAINS A CURRENT TIME, POSITION, ALTITUDE, AND SPEED; AND
· ACHIEVES THE DESIRED ACCURACY.
YOU SHOULD USE THE CONT MODE WHEN THE PLGR IS POWERED BY YOUR VEHICLE POWER.
IN FIX MODE, THE PLGR WILL AUTOMATICALLY CHANGE TO STANDBY (STBY) MODE AFTER IT:
· DETERMINES PRESENT POSITION
· REACHES AUTOMATIC TIMEOUT
THE PLGR DOES NOT TRACK SATELLITES WHEN IN STANDBY MODE, SO LESS BATTERY POWER IS USED. WHEN THE PLGR IS POWERED BY BATTERY ALONE, THE FIX MODE IS SELECTED AUTOMATICALLY. YOU SHOULD USE THE FIX MODE DURING DISMOUNTED OPERATIONS.
REMOVE VGT PLGR-17.
VGT PLGR-17
Operating SHOW VGT PLGR-18, PLGR - Operating Modes, Continued.
Modes,
Continued
USE THE AVG, OR AVERAGING, MODE WHEN YOU REQUIRE AN ACCURATE POSITION READING. FOR BEST ACCURACY:
· DO NOT MOVE THE RECEIVER WHILE IN AVG MODE.
· ALLOW THE RECEIVER TO REMAIN ON FOR 15 MINUTES OR LONGER,
DEPENDING ON THE DESIRED ACCURACY LEVEL.
IF THE ANTENNA IS MASKED AND YOU CAN’T MOVE TO A BETTER LOCATION, USING AVG FOR 5 TO 10 MINUTES WILL IMPROVE ACCURACY.
USE TIME MODE WHEN ONE PULSE PER SECOND (1PPS), SINCGARS, OR HAVE QUICK FUNCTIONS ARE THE ONLY OUTPUTS REQUIRED. BEFORE SELECTING TIME MAKE SURE THE RECEIVER HAS ACQUIRED SATELLITES--OR THAT YOU HAVE ENTERED YOUR PRESENT POSITION. THE PLGR TRACKS UP TO FIVE SATELLITES IN TIME MODE, AND YOU NEED ONLY ONE FOR ACCEPTABLE ACCURACY.
REMOVE VGT PLGR-18.

Operating SHOW VGT PLGR-19, PLGR - Operating Modes, Continued.
Modes,
Continued
IN STBY, OR STANDBY, MODE THE PLGR ACCEPTS NEW INPUTS AND UPDATES DISPLAYS, BUT IT DOES NOT ACQUIRE OR TRACK SATELLITES. THE STBY MODE REQUIRES FAR LESS POWER, THUS EXTENDING BATTERY LIFE WHEN USING INTERNAL PLGR POWER. OPERATING IN STBY ALSO REDUCES BATTERY CONSUMPTION WHEN TRANSFERRING WAYPOINTS OR ALMANAC INFORMATION.
THE TNG, OR TRAINING, MODE HAS PRE-STORED, OR CANNED, POSITION AND NAVIGATION DATA FOR USE WITH THE OPERATION AND MAINTENANCE MANUAL TUTORIAL. THE TNG MODE WILL NOT ACQUIRE OR TRACK SATELLITES.

DURING SETUP . THE DATUM ID OF THE WAYPOINT BEING ENTERed OR
EDITed MUST MATCH THE DATUM OF THE MAP IT IS FROM.
· LINE 2 CONTAINS THE HORIZONTAL DATUM NAME THAT MATCHES THE
DATUM ID IN LINE 1.
· LINE 3 CONTAINS THE MAGNETIC VARIATION:
· "MVAR:NO mvar" OR "MVAR:xnnn.no - WHEN ENTERing OR EDITing THIS FIELD
IT DISPLAYS "NO MVAR," WHICH MEANS THE WAYPOINT WILL USE THE
MVAR SELECTED DURING SETUP. IF WAYPOINT MAP DATUM IS CHANGED,
YOU MUST ALSO ENTER THE MAGNETIC VARIATIONASSOCIATED WITH THAT
MAP DATUM. TO ENTER OR EDIT THE MVAR, MOVE CURSOR TO "NO MVAR"
FIELD AND SELECT IT WITH AN UP OR DOWN ARROW. THE FIELD NOW
DISPLAYS "E000.0o." SELECT EITHER "E" OR "W." INPUT THE NUMERIC
VALUE VIA KEYPAD OR SCROLL.
· LINE 4 CONTAINS TWO FIELDS:
· COORDINATE FORMAT - WHEN YOU ENTER OR EDIT THIS FIELD, THE
DISPLAY SHOWS THE COORDINATE FORMAT SELECTED AT SETUP. IF THIS
WAYPOINT IS FROM A MAP WITH A DIFFERENT COORDINATE FORMAT,
