Checking GPS and
WAAS status
Once the 958 is on and has acquired its satellite data, you can
always check the quality of the GPS signals by viewing the
various satellites’ SNR reading (Signal-to-Noise Ratio) as
described in see ”Viewing GPS satellite status” starting on page
62.
Turning the radar
on
If you have radar installed and connected to Port 2, it won’t be
operational until you turn on the radar transmitter. See
”Turning radar on and off” beginning on page 128.
Turning the 958 off
To turn the 958 off, press and hold the
PWR
key for a few
seconds until the screen goes dark.
Displaying the chart screen
Displaying your
vessel’s present
position
After the 958 successfully completes its start-up sequence,
press the
CHART
function key to display the
CHART
screen.
You’ll see your present position represented by a black
triangular vessel symbol in the center of the chart. The
DGPS
or
WAAS
indicator on the right side of the screen means the
958 is currently receiving radiobeacon (optional) or WAAS
signals. White areas are water and brown areas are land. If
you’re using a chart cartridge, nav aids and depth contours are
shown as well as landmark names.
