To turn the RayChart off, press and hold the POWER key for three
seconds. A countdown timer is displayed, and if you release the key
before the timer reaches zero the RayChart will remain on. Otherwise,
when the timer reaches zero the RayChart display is cleared and the
key lights go off.
2.3 The Chart Display
Once the position fix has been established, the screen shows the chart
area and associated data that were displayed when the RayChart was
last used. If this is the first time it has been turned on, and no chart card
is installed, the display shows the small-scale chart at 0°/0°, and the
default soft key labels.
An example RayChart chart display, in its default configuration but with
a chart card installed, is shown in the top illustration opposite.
The cursor data box normally provides the following information:
• The cursor position, in either latitude and longitude or TDs,
depending on your setup
• The vessel’s Course Over Ground (COG) and Speed Over Ground
(SOG)
• A mileage scale ruler in nautical miles
• The cursor’s bearing (BRG) and range (RNG) from your vessel’s
current position
The cursor data box is also used to display the vessel’s position and the
range and bearing to the active waypoint, when the RayChart is in
Home Mode (see Section 3.2).
Note: If required, you can use the setup options to change the units in
which information is displayed, turn off the cursor data box and soft key
labels, and change the chart orientation (see Chapter 6).
The chart display can show additional information, depending on the
current data and on your setup selections, as shown in the example
RayChart display in the bottom illustration opposite.
