BRIEF OVERVIEW OF NAVIGATOR USE: FIRST STEPS 43
When using the GPS receiver for the first time, do
as follows:
1. Go to an open site outdoors, with unobstruct-
ed view of the sky.
2. Position the GPS antenna and turn the GPS re-
ceiver to
Full power mode.
3. Hold the phone still and wait until the GPS in-
dicator shows bars, signifying that your posi-
tion has been successfully calculated. This may
take a few minutes.
4. Wait one more minute before turning the GPS
receiver off, changing it to
Low power mode, or
going indoors.
GPS RECEPTION
Once the GPS receiver has been activated, finding
satellites and locking to them usually happens
within a few minutes. At least three suitably posi-
tioned satellites are needed for two-dimensional
position calculation, while four or more make
three-dimensional calculation (including eleva-
tion) possible.
The GPS indicator shows no bars while the GPS re-
ceiver is searching for satellites. As soon as posi-
tion has been determined, the accuracy of position
determination is shown by the bars in the indica-
tor. The more bars the better the accuracy.
You can also view the status of individual satellites
on the
Position navigator page. For further infor-
mation, please see the following chapter Position.
POOR GPS COVERAGE
If the GPS receiver is unable to determine your cur-
rent position within a few minutes, the text
Poor
GPS coverage
will be shown. This happens when
not enough satellites are visible.
If the GPS has been set to
Economy, At intervals, or
Low power mode, the GPS starts sleeping to con-
serve battery as soon as it detects poor GPS cover-
age. This is indicated by a
ZZZ symbol in the place
of the GPS indicator bars.
When sleeping, the GPS receiver will wake up au-
tomatically every few minutes and look for satel-
lites. It will go back to sleep if adequate satellite
coverage is not available.
When using the
Economy or At intervals mode, po-
sition found at the latest attempt is indicated by a
grey bar symbol. When using the
Low power mode,
previously searched and found position is indicat-
ed by a black bar symbol.
