Configuring City Data Settings
The Moon phase and tide graph information displayed by this watch differ
according to your geographic location. Before using this watch to produce
such information, be sure to make the proper city data settings to specify your
current location.
• The lunitidal interval is the time elapsing between the Moon’s transit over
the meridian and the next high tide. See “Lunitidal Interval” for more
information.
• This watch displays lunitidal intervals in term of hours and minutes.
• GMT differential is the difference between the time in the displayed time
and Greenwich Mean Time (GMT).
To configure city data settings
1. In the Timekeeping Mode, hold down A
until the second’s digits starts to flash,
which indicates the setting screen.
2. Press A again to display the city data
setting screen, with the GMT differential
flashing.
• Press D to move the flashing in the
sequence shown below to select other
settings.
3. Use E (+) and B (–) to change the setting of the currently selected
(flashing) item.
• The “CITY DATA LIST” provides city data information for a number of
GMT differentials, longitudes, and lunitidal intervals around the world.
• You can change the GMT differential setting in units of 0.5 (half an
hour).
• Longitude can be specified in the range of 179°W to 180°E, in 1-degree
steps.
4. Press A to exit the setting screen.
DIGITAL COMPASS
A built-in bearing sensor detects magnetic north and indicates one of 16
directions on the display. Direction readings are performed in the Digital
Compass Mode.
• You can calibrate the bearing sensor if you suspect the direction reading is
incorrect.
To enter and exit the Digital Compass Mode
While in the Timekeeping, Barometer/Thermometer, or Countdown Timer/
Stopwatch Mode, press B to enter the Digital Compass Mode.
• At this time, the watch immediately starts a Digital Compass operation.
After about two seconds, letters appear on the display to indicate the
direction that the 12 o’clock position of the watch is pointing.
• Press D to return to the Timekeeping Mode.

To take a direction reading
1. Enter the Digital Compass Mode.
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. Point the 12 o’clock position of the watch in
the direction you want to determine.
4. Press B to start a Digital Compass
reading operation.
• After about two seconds, the direction
that the 12 o’clock position of the watch
is pointing appears on the display.
• Also, four pointers appear to indicate
magnetic north, south, east, and west.
• Direction reading continues for the
amount of time that is currently
specified for the continuous reading
time.
• The COMP indicator flashes on the
display while a reading is in progress.
• The direction value that appears on the
display represents the clockwise angle
formed between magnetic north (which
is 0 degrees) and the displayed
direction.

Note
• Note that taking a measurement while the watch is not horizontal (in
relation to the horizon) can result in large measurement error.
• Pressing B while in the Digital Compass Mode starts a new direction
measurement operation.
• The following table shows the meanings of each of the direction
abbreviations that appear on the display.
• You can adjust the rotary direction bezel so
that the “
” (or “N”) is aligned with the
magnetic north pointer. This correctly aligns
all of the markings on the bezel.
• The Digital Compass operation is
momentarily interrupted while an alarm
(Daily Alarm or Hourly Time Signal) or beep
(progress or time up beeper) is sounding, or
while the backlight is turned on by the Auto
Light Switch. If this happens, start the
Digital Compass operation again from the
beginning.
• See “Digital Compass Precautions” for other
important information about taking direction
readings.
Making Digital Compass Settings
You can set up the watch so it takes continuous direction readings for an
amount of time specified by you.
To configure the Digital Compass Mode
1. In the Digital Compass Mode, hold down
A until the upper display area shows
, which indicates the setting screen.
2. Press D twice to display the continuous
reading time setting screen.
3. While the continuous reading time digits
are selected (flashing), use E (+) and B
(–) to change the setting in increments of
10 seconds.
• You can specify a continuous reading
time in the range of 0'00'' to 1'00''.
Setting 0'00'' causes digital compass
operation to stop after a single reading.
4. Press A to exit the setting screen.
