Viewing Time Stamp Records (Time Recall)
You can use the Time Recall Mode to view time stamp records you created in the Timekeeping Mode and
other modes.
To create a time stamp record
To create a time stamp record, hold down
B
for about one second in any mode until the watch beeps.
•
REC
will appear on the display, indicating that a record of the current date and time was created.
To view time records
1. In the Timekeeping Mode, press
C
twice.
•
This enters the Time Recall Mode.
REC
appears on the display for
one second, followed by the newest time record.
•
Refer to page E-26 for information about navigating between modes.
•
Pressing
A
displays the date (year, month day) and time for about
two seconds.
2. Use
D
to select the record you want.
•
Each press of
D
scrolls through log records in sequence, from
newest (record number
-01-
) to the oldest (record number
-20-
).
•
Pressing
D
displays the previous record, pressing again displays
the record before that one, and so on.
•
Holding down
D
scrolls log records at high speed.
•
Records are numbered so an older record has a lower number.

Location
•
Taking a direction reading when you are near a source of strong magnetism can cause large errors in
readings. Because of this, you should avoid taking direction readings while in the vicinity of the
following types of objects: permanent magnets (magnetic necklaces, etc.), concentrations of metal
(metal doors, lockers, etc.), high tension wires, aerial wires, household appliances (TVs, personal
computers, washing machines, freezers, etc.)
•
Accurate readings are impossible indoors, especially inside ferroconcrete structures. This is because
the metal framework of such structures picks up magnetism from appliances, etc.
•
Accurate direction readings are also impossible while in a train, boat, air plane, etc.
Storage
•
The precision of the bearing sensor may deteriorate if the watch becomes magnetized. Because of
this, you should store the watch away from magnets or any other sources of strong magnetism,
including: permanent magnets (magnetic necklaces, etc.), concentrations of metal (metal doors,
lockers, etc.), and household appliances (TVs, personal computers, washing machines, freezers, etc.)
•
Whenever you suspect that the watch may have become magnetized, perform the procedure under “To
perform fi gure 8 calibration” (page E-70) or “To perform 3-point calibration” (page E-72).

2. During the 60 seconds that digital compass readings are being taken, press
A
to store the current
reading in Bearing Memory.
•
The Bearing Memory direction angle is displayed for about one second as it is stored in Bearing
Memory. After that, the Bearing Memory screen (which shows the bearing memory direction angle
and pointer) will appear, and a new 60-second direction reading operation will start.
•
You can press
D
at any time while the Bearing Memory screen is displayed, to start a new
60-second direction reading operation. Doing so will display the direction angle for the direction
that the 12 o’clock position of the watch is pointed. The direction angle of the current reading will
disappear from the display after the 60-second direction reading operation is complete.
•
During the fi rst 60 seconds after you display the Bearing Memory screen or during a 60-second
direction reading operation you triggered by pressing
D
while the Bearing Memory screen is on
the display, the direction stored in memory is indicated by a Bearing Memory pointer.
•
Pressing
A
while the Bearing Memory screen is displayed will clear the reading currently in
Bearing Memory and start a new 60-second direction reading operation.
Digital Compass Precautions
Magnetic North and True North
The northerly direction can be expressed either as magnetic north or true
north, which are different from each other. Also, it is important to keep in
mind that magnetic north moves over time.
•
Magnetic north is the north that is indicated by the needle of a
compass.
•
True north, which is the location of the North Pole of the Earth’s axis, is
the north that is normally indicated on maps.
•
The difference between magnetic north and true north is called the
“declination”. The closer you get to the North Pole, the greater the
declination angle.

Using Bearing Memory
Bearing Memory lets you temporarily store and display a direction reading
so you can use it as a reference as you take subsequent digital compass
readings. The Bearing Memory screen displays the direction angle for the
stored reading, along with a pointer that indicates the stored reading.
When you take digital compass readings while the Bearing Memory
screen is displayed, the direction angle of the current digital compass
reading (as read from the 12 o’clock position of the watch) and the stored
Bearing Memory direction reading will both be shown.
To store a direction angle reading in Bearing Memory
1. Press
D
to start a digital compass reading operation (page E-64).
•
This will take an initial reading and then take readings every
second for 60 seconds.
•
If a bearing memory direction angle value is already displayed, it
means that there is a reading already stored in Bearing Memory. If
this happens, press
A
to clear the Bearing Memory reading and
exit the bearing memory screen before performing the above step.

To perform magnetic declination correction
•
Keep the watch level and don’t move it during the calibration process.
•
For information about magnetic declination, see “Magnetic North and True North” (page E-77).
1. In the Digital Compass Mode, hold down
A
for at least two seconds.
SET Hold
will fl ash on the display and then
CAL
will appear. Keep
A
depressed until
CAL
appears.
2. Press
C
twice.
•
DEC
will appear on the display and then the current magnetic
declination angle setting will fl ash on the display.
3. Use
D
(East) and
L
(West) to change the settings.
•
The following explains magnetic declination angle direction
settings.
OFF
: No magnetic declination correction performed. The magnetic
declination angle with this setting is 0°.
E
:
When magnetic north is to the east (east declination)
W
:
When magnetic north is to the west (west declination)
•
You can select a value within the range of W 90° to E 90° with
these settings.
•
You can turn off (
OFF
) magnetic declination correction by pressing
D
and
L
at the same time.
•
The illustration, for example, shows the value you should input
and the direction setting you should select when the map shows a
magnetic declination of 1° West.
4. When the setting is the way you want, press

to exit the setting
screen.

4. Leaving the watch pointed upwards, rotate it as precisely as possible
180 degrees from point 1.
5. Keeping the watch parallel to the ground, press
D
to calibrate Point 2.
•
WAIT
is shown on the display while calibration is being performed.
•
When calibration is successful, the words
TURN
and
OVER
will
alternate on the display. After that,
-3-
will appear on the display.
•
If calibration fails for some reason, return to step 2 of this
procedure and try again.
6. Turn over the watch so its face is pointed at the ground.
•
In this case, it makes no difference what direction the 12 o’clock
position of the watch is pointed.
7. With the watch pointed downwards and parallel with the ground as
shown in the illustration, press
D
.
•
This starts calibration of Point 3.
•
WAIT
is shown on the display while calibration is being performed.
•
If calibration is successful, the watch will beep once. Also, the
watch will display
OK
and start taking a direction reading. This
indicates that calibration is complete.
•
If the watch beeps three times and displays
ERR
, perform the
procedure from step 3 again.
