7-5 Obtaining a GPS Fix
Your handheld receives GPS signals through the GPS Receiver. In order for the receiver to receive signals:
1
Your handheld must be outside or in a vehicle parked outside – sunlight alone is not suf
fi
cient (e.g. through the
window of a building).
2
Position the GPS Receiver:
•
With a good view of the sky.
•
Away from buildings, trees or large metal objects.
•
Away from sources of electrical interference.
When you
fi
rst power on your handheld or if Smart
S
Professional has not had a
fi
x for several hours, it may take
several minutes to obtain a GPS
fi
x. You can minimize the amount of time that this takes by remaining stationary in your
vehicle until Smart
S
Professional has a position
fi
x.
7-6 To Check GPS Reception
You will know when Smart
S
Professional has a GPS
fi
x by the symbols
on your Map Screen. When Smart
S
Professional has no
fi
x, the position
indicator in the middle of the screen will be colored red and the words
“Waiting for GPS” will be displayed. Also, while Smart
S
Professional is
attempting to obtain a
fi
x, you will notice that there are no route instructions
displayed on the Map Screen.
To check GPS reception at any time, return to the
MAIN MENU
and select
GPS STATUS
(see Section 12-2 GPS Settings). If the GPS receiver is only
receiving signals from a few satellites, consider moving the GPS receiver to
a more open place.
Tip: In order to
attain good GPS
performance, signals
must be picked up
from three or more
satellites. To check
satellite reception,
see Section 12 Using
the GPS Status
Information.
Note: The position
icon
indicates your
current position. A
red pointer indicates
no GPS
fi
x and a blue
pointer indicates a
valid GPS
fi
x.
