NAVIGATION MODE
The Navigation Mode provides you with storage for up to five sets of direction
and temperature data. Each set of data includes direction, temperature, and
the time the readings were taken.
Taking Navigation Mode readings
1. In the Navigation Mode, use A to select
the memory area where you want to store
the data. Each time you press A, the
selected memory area changes in the
following sequence.
Each memory area is identified by a number
from
1 through 5. The Initial Screen shows
the current time without a memory number.
Navigation Mode data is not stored in
memory if you perform the following steps
while the Initial Screen is on the display.
2. Place the watch on a flat surface or (if you
are wearing the watch), make sure that
your wrist is horizontal (in relation to the
horizon).
3. Press C to take a reading.
After about one second, the current
temperature, direction pointers, and a
direction value appear on the display.
You can repeat steps 1 through 3 as many
times as you like.
4. Next, you can adjust the rotary direction
bezel so that the “N” or “L” mark is aligned
with the magnetic north pointer. This
correctly aligns all of the markings on the
bezel.
See “Temperature and Direction Reading
Precautions” and “Digital Compass
Precautions” for other important information
about taking direction and temperature
readings.
Recalling Navigation Mode Data
While in the Navigation Mode, use A to scroll
through the data in the following sequence.
Deleting All Navigation Mode Data
While in the Navigation Mode, hold down A and C for about two seconds,
until the direction value changes to
---. This indicates all Navigation Mode
memory data is deleted.
You cannot delete individual memory area contents.

WORLD TIME MODE
The World Time Mode shows you the
current time and average temperatures
in 27 cities (29 time zones) around the
world.
For full information on city codes, see
the “CITY CODE TABLE”.
The time settings of the Timekeeping
Mode and the World Time Mode are
independent from each other, so you
must make separate settings for each.
Whenever you change the time setting
for any city in the World Time Mode,
the settings of all other cities are
changed accordingly.
Selecting a World Time City and Viewing Its Time and
Temperature Information
1. In the World Time Mode, press C to
scroll forward through the city codes
(time zones) and B to scroll back.
When you display the screen of a city,
its time and GMT differential appear
first. Next, the GMT differential display
changes to the current Timekeeping
Mode time.
2. Press A to display the average
temperature in the displayed city for
the currently selected month.
3. Press C to scroll forward through the
months and B to scroll back.
No average temperature data is
shown when
GMT or --- is
indicated as the city.
Press A to return to the current time
screen for the selected city.
Setting the World Time
1. In the World Time Mode, use B and C to
scroll through the city codes and find the
one you want.
2. Hold down A until the DST On/Off setting
starts to flash on the display.
The DST On/Off setting is flashing because
it is
selected
.
3. Press D to move the flashing in the
sequence shown below to select other
settings.
While DST setting is selected (flashing), press C to toggle Daylight Saving
Time on (
DST) and off (OFF).
While hour or minutes is selected (flashing), press C to increase the
setting or B to decrease it.
4. After you set the time, press A to return to the World Time screen.
Daylight Saving Time (DST)
Daylight Saving Time automatically advances the time setting by one hour
from Standard Time. You can make individual Daylight Saving Time settings
for each city code (time zone). Remember that not all countries or even local
areas use Daylight Saving Time.
To switch between Standard Time and Daylight Saving Time
1. In the World Time Mode, use B and C to display the city code (time
zone) whose standard time/daylight saving time setting you want to
change.
2. Hold down A until the DST On/Off setting starts to flash on the display.
3. Press C to toggle between Daylight Saving Time (
DST) and Standard
Time (
OFF).
4. After you are finished making the setting you want, press A to return to
the World Time screen.
The DST indicator is on the display whenever you display a city code for
which daylight saving time is turned on.
