In this section, PLGR screens are shown in double lined boxes while ANCD screens

continue to be shown as dark bordered rectangles.

A battery powered PLGR will automatically go to standby as soon as satellites have

been acquired.

* **

Time Figure of Merit (TFOM) of 8 or less indicates that PLGR is tracking at least one

satellite and PLGR time is GPS accurate. For TFOM 9, wait for PLGR to acquire satellites, at

which time TFOM will change from 9 to 8 or less. (When first turned on, the PLGR may take as long

as 15 minutes to acquire satellites.)

****

When the date read from the PLGR is entered into the ANCD, it is automatically

converted to the two-digit Julian Date needed for SlNCGARS sync time.
