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.
If you have radar installed and connected to Port 2, it won't be
operational until you turn on the radar transmitter. See
on
"Turning radar on and off" beginning on page 128.
To turn the 958 off, press and hold the PWR key for a few
seconds until the screen goes dark.
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.
