Use the up or down cursor arrow keys to point to the desired waypoint,
and press ENTER. The 941X will search for, and present, the nine closest
tide stations to this waypoint. Now, use the up and down arrow keys to
point to the desired station, and press ENTER twice to return to the
TIDE TRACK screen and display the tides for that station.
The TIDE TRACK screen normally displays tide information for today's
date.
To enter a different date, press the CONFIG menu key; the TIDE
TRACK CONFIGURATION screen is displayed. Press the NEW DATE
menu key. The first character of the present tide date flashes. If neces-
sary, press the right cursor arrow to move to the month or digit you wish
to change. To change a digit, press that key on the keypad. To change the
month, use the up and down cursor arrow keys. When the date is correct,
press ENTER twice. Tide information for the new date is now displayed.
As we previously discussed in "Comparing GPS and Loran," beginning on
page 5, use of differential corrections significantly enhances the accuracy
and performance of your 941X. One source of differential corrections is
Northstar's fully automatic beacon receiver, which may be connected
externally (part #8800) to the 941X, or contained internally (#8500).
Or, you may connect another source of corrections externally (see page
124 for further details on interfacing to external sources of differential
corrections).
The Northstar beacon receiver takes corrections broadcast by shore-
based marine radio beacons situated along most of the U.S. coastline.
