Bearing Mode
The Bearing Mode lets you determine approximate
directions using a displayed angle value that indicates the
angle to the sun (solar azimuth).
•
All of the operations in this section are performed in the
Bearing Mode, which you enter by pressing
A
.
Important!
Before the watch can calculate the solar azimuth (the
angle of the sun in relation to your location) correctly, you
must first set the correct current time, current date, and
Home Site in the Timekeeping Mode. You must also
specify whether the sun traverses the sky to the north or
to the south of your current position.
•
Note that you cannot use the Bearing Mode to
determine directions in the following cases.
Solar azimuth
When the sun is not visibl
e
At night
When sun traverses the sky directly overhead or when you cannot determine if it
traverses to the north or south
To set the traverse direction of the sun
1. In the Bearing Mode, hold down
C
until
N
or
S
flashes
on the display. This indicates the setting screen.
2. Press
D
to toggle the setting between
N
(north) and
S
(south).
3. Press
C
to exit the setting screen.
•
At this time the watch uses the traverse direction setting
you just made and the Timekeeping Mode data to
calculate and display the solar azimuth.

To determine your bearings
1. Enter the Bearing Mode.
•
This displays the current solar azimuth value in accordance with the current
Timekeeping Mode data (time, date, Home Site data).
2. Find the same value on the bezel as the angle value displayed for the solar azimuth
on the Bearing Mode screen.
3. Position the watch so the value you found in step 1 is pointing at the sun.
4. The 12 o’clock position of the watch should now be pointed north.
•
Note that the bearings produced by the Bearing Mode are intended for general
reference only.

Moon/Tide Data
Moon/tide data lets you view the Moon age and Moon
phase for a particular date, and tidal movements for a
particular date and time for the Home Site.
•
If you suspect that the Moon/tide data is not correct for
some reason, check the Timekeeping Mode data
(current time, date, and Home Site settings), and make
changes as required.
•
See “Moon Phase Indicator” for information about the
Moon phase indicator and “Tide Graph” for information
about the tide graph.
•
All of the operations in this section are performed in the
Moon/Tide Data Mode, which you enter by pressing
B
.

Timekeeping Mode.

To view the Moon data for a particular date
While the Moon Data screen is displayed in the Moon/Tide Data Mode, use

•
You can select any date from 2000 to 2039.
To view tide data for a particular time
1. While the Moon Data screen is displayed in the Moon/Tide Data Mode, use
D

and
A
(–) to display the date whose tide data you want to view.
2. Press
C
to switch to the Tide Data screen.
•
The initial screen shows the tide graph for 6:00 AM.
3. Specify the time for which you want to display tide data.
•
Use
D
(+) and
A
(–) to change the time in one-hour steps.
Countdown Timer
The countdown timer can be set within a range of one
minute to 60 minutes. An alarm sounds when the
countdown reaches zero. The countdown timer has two
modes: auto-repeat and elapsed time, and a progress
beeper signals the progress of the countdown. All of this
makes the countdown timer a valuable tool for timing the
start of a yacht race.
•
All of the operations in this section are performed in the
Countdown Timer Mode, which you enter by pressing
B

Configuring the Countdown Timer
The following are the settings you should configure before actually using the
countdown timer.
Countdown start time and reset time
Timer mode (auto-repeat, elapsed time)
Progress beeper on/off
•
See “To configure the countdown timer” for information about setting up the timer.
Reset Time
You can set a “reset time,” which is a kind of alternate countdown start time you can
recall with the press of a button any time a countdown operation is in progress.
Timer Mode
The countdown timer gives you a choice of two modes: auto-repeat and elapsed time.
Auto-repeat
Auto-repeat mode automatically restarts the countdown from the countdown start time
you set whenever zero is reached.
•
Auto-repeat mode is best when timing the starts of match races.
•
Even if you start a countdown operation from the reset time, the countdown
automatically restarts from the countdown start time whenever it reaches zero.
•
Auto repeat timing repeats up to seven times.
Elapsed Time
When the end of the countdown is reached in the elapsed time mode, the timer
automatically switches to an elapsed time measurement operation.
•
The elapsed time mode is best when timing the speed of yachts during ocean races.
•
The elapsed time operation is performed in one-second increments up to 99 hours,
59 minutes, 59 seconds.
Countdown Timer Beeper Operations
The watch beeps at various times during a countdown to so you can keep informed
about the countdown status without looking at the display. The following describes the
types of beeper operations the watch performs during a countdown.
Countdown End Beeper
The watch beeps each second of the final 10 seconds before a countdown reaches
zero, and at zero. The first five beeps (seconds 10 through 6) are higher pitched than
the final five beeps (seconds 5 through 1). The watch emits a longer beep to signal
when the countdown reaches zero.
•
The countdown end beeper always sounds, regardless of the on/off status of the
progress beeper.
Progress Beeper
The progress beeper actually includes two beepers: a reset time beeper and a reset
period progress beeper.
•
The reset time beeper and reset period progress beeper sound only while the
progress beeper is turned on.
Reset Time Beeper
The reset time beeper is similar to the countdown end beeper. When the progress
beeper is turned on, the watch beeps each second of the final 10 seconds before the
countdown reaches the reset time.
Reset Period Progress Beeper
The reset period is the portion of the countdown between the reset time and zero.
When the progress beeper is turned on, the watch emits four short beeps at the top of
each minute during the reset period, and 30 seconds before the end of the
countdown.
