The 957 plots your position on the CHART screen. Nearby land
masses, depth contours, nav aids, waypoints, avoidance areas,
and a lat/lon grid may be displayed, along with your vessel's
image. When you're using the 957 as a chart plotter, the menu
keys to the right of the display screen let you perform the
following functions:
•
restart the desired track line to run directly from your
position to the waypoint, "zeroing" the cross-track error
display
change the options available for the CHART screen
•
display additional position information in the INFO BAR at
•
the bottom of the screen
•
go to a waypoint, nav aid, or unmarked point you select
on the CHART screen by pressing the CURSOR PAD
When the display screen is at full brightness, if the 957
becomes too hot inside due to the outside temperature and
sunlight, the display screen will automatically dim.
Auto-dimming helps maintain the integrity of the display and
reduce power consumption when the 957 is on and running
too hot for its current environment. You can override the
auto-dim function at any time by increasing the brightness
with the BRIGHTNESS key. The 957 may dim again as
required so as not to exceed the maximum internal
temperature.
Occasionally, the 957 needs to tell you something or ask
permission to do something. When this happens, a special
information or question window appears on the display. This
window may contain an alarm icon, or an INFO label or a large
question mark along with a message for you to read.
Flashing alarm icons
The 957 communicates alarm messages by flashing an alarm
icon on the bottom right side of the screen. Alarm messages
contain information you may want to read as soon as possible.
To see the alarm condition on the ALARMS screen, press the
