When position recall is enabled, the system automatically
saves the current GPS location of the vehicle – specif-
ically, the receiver – before the ignition switch is turned
OFF. When the ignition switch is turned ON again, the
saved GPS location is used to restart the converging
process. Using the last known GPS coordinates reduces
the signal convergence time.
To take advantage of this feature:
• You must turn the system OFF while the signal is al-
ready converged—that is, receiving proper GPS input
to record. If the vehicle is left in the field or an open
outdoor area at the end of the work session, the current
coordinates are saved. If the vehicle is moved inside a
building, the signal is blocked and no coordinates are
saved. If the vehicle is always powered down inside a
building, position recall should not be enabled since it
will not reduce convergence time.
• You must not move the vehicle—not even a short dis-
tance—between the time you turn the ignition switch
OFF and the time that initialization is complete.
NOTE: Initialization is not the same as convergence.
With position recall enabled, do NOT move the vehicle
until you check system status when the vehicle is turned
ON.
After the display starts up, an information message dis-
plays: "In progress, please wait. Do not move [the] vehicle
until complete or convergence time will be increased. Has
the vehicle been moved since [the system was] turned
off?
You must answer this question correctly. Failure to do so
may prevent the system from converging at all.
• If the vehicle was moved, press the "Yes" button to clear
the message. Convergence will occur without position
recall. A message displays: "RTX convergence has
been restarted. A full convergence time can be ex-
pected. You may move the vehicle in the meantime."
