Arrival Alarm - If you set the arrival alarm’s distance to a small number,
and you run a route (see the routes section), the GlobalNav 12 may not
show navigation data to the next waypoint, once you arrive at the first
one, since you may not be able to come close enough to the first waypoint
to trip the arrival alarm.
MESSAGES
The position and DGPS message selections are found on the Alarms/
CDI menu. When turned on, the position message appears for a few sec-
onds whenever the unit locks onto the satellites and shows a position. It
also appears when the unit loses the lock onto the satellites and cannot
navigate. Pressing the EXIT key erases these messages.
The DGPS message appears whenever the unit begins or stops using
DGPS data to help determine your position.
The default setting for these messages is “on”. To turn either message off,
select the “Setup Alarms” menu from the main menu, then highlight the
desired message and press the left arrow key.
SUNRISE/SET MOONRISE/SET CALCULATOR
This unit has a sunrise/sunset and moonrise/moonset
calculator that shows this information anywhere or any-
time in the world. To use it, press the MENU key, then
highlight the Sun/Moon Calc label and press the right
arrow key. Highlight either the sun or moon calculator
and press the right arrow key. The screen shown at
right appears if you chose the sunrise calculator. (Both
calculators work identically. We’ll concentrate on the
sunrise/sunset calculator for this example.) The sun-
rise and sunset for today’s date appear in the center of
the screen. Today’s date shows at the top of the screen.
If you want to know the sunrise/sunset for a different date, press the ENT
key, then enter the new date. The unit returns to the
sunrise/sunset calculator screen with the sunrise and
sunset times shown for the date you entered.
The sunrise and sunset show for your present posi-
tion. If you move the plotter’s cursor to a different posi-
tion before using this calculator, it will show the sun-
rise/sunset for the cursor’s location.
The moonrise/moonset calculator works identically to
the sunrise/sunset calculator. It looks like the screen at
