NOTE:
If you’re viewing and editing information on the
RECEIVER
INFORMATION
screen, and you press one of the five function
keys to view other data, your edit-in-progress is immediately
cancelled so that you can view the data requested by your function
keypress. To resume editing at the
RECEIVER INFORMATION
screen, you must return to that screen and re-enter the data you lost
when you pressed the function key. To purposely cancel an
edit-in-progress, however, you’d normally press the
CANCEL
key.
Changing GPS speed averaging value
When you aren’t using DGPS or you’re out of range, you may
notice that the SOG readings obtained from the GPS satellite
system are slightly erratic, varying by up to several knots. The
GPS SPEED AV
function often can improve the steadiness of
these readings, although you’ll see a slightly longer
display-reaction time when the speed changes.
With GPS speed averaging, you can select the time over which
your speed is averaged, with available values between one and
ten seconds. A longer averaging time is useful at lower speeds
when you require the highest accuracy. With this high degree
of accuracy, you’ll see a steady display of your speed that’s
slow to change. A shorter averaging time, however, provides
less accuracy and a quicker-changing display of your speed.
You also can turn off speed averaging completely for the
quickest possible display-reaction time.
You can change the speed averaging value at any time without
affecting other navigation functions.
To change the speed averaging value:
1. At the
RECEIVER INFORMATION
screen, press the
CURSOR PAD
to highlight the
GPS SPEED AV
field, then
press the
EDIT
key.
2. Press the
CURSOR PAD
left or right to select an averaging
time in seconds of
1, 2, 5
,
10
, or
OFF
.
3. Press
ACCEPT
to make the change, or
CANCEL
to leave
the option unchanged.
