Position Acquisition; Position/Navigation Screens - Lowrance 100 Installation And Operation Instructions Manual

thereby giving it the data it needs to determine which satellites are in
view. Once the satellites are known, the receiver searches for only those
satellites, making a lock faster than an auto search method.

Position Acquisition

When the receiver locks onto the satellites and calculates a position, it
shows the message "Position Acquired" on the screen. All position and
navigation data flashes until the unit acquires a position. Do not rely on
any data that is flashing! When the numbers are flashing, they represent
the last known values when the unit lost it's lock on the satellites.
(Note: The altitude data may still flash even if the unit shows a "Position
Acquired" message and all other data is not flashing. The unit must be
locked onto at least four satellites to determine altitude. It only takes three
satellites to determine position. You can navigate with this unit if the alti-
tude is flashing, simply ignore the altitude display until it quits flashing.)
REMEMBER, DO NOT NAVIGATE WITH THIS UNIT UNTIL THE
NUMBERS STOP FLASHING!
Once the unit has acquired the satellites and is showing a fix on the sta-
tus screen, or the position acquired message appears, it's ready for use.
