Chapter 2 - Introducing the 958
Adjusting the brightness
The fluorescent tubes that illuminate the 958 slowly dim after
several thousand hours of use. If you use your 958 for many
hours each day, you may want to keep the level of the display
lighting low when you don’t really need it. To adjust the
screen’s brightness, press the
BRIGHTNESS
key: Pressing the
upper arrow brightens the screen; pressing the lower arrow
darkens it.
Chart plotter
function
The 958 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 958 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
Auto-dimming
When the display screen is at full brightness, if the 958
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 958 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 958 may dim again as
required so as not to exceed the maximum internal
temperature.
