Precautions Concerning Simultaneous Measurement of Altitude and Temperature
Though you can perform altitude and temperature measurements at the same time, you should remember
that each of these measurements requires different conditions for best results. With temperature
measurement, it is best to remove the watch from your wrist in order to eliminate the effects of body heat.
In the case of altitude measurement, on the other hand, it is better to leave the watch on your wrist,
because doing so keeps the watch at a constant temperature, which contributes to more accurate altitude
measurements.
• To give altitude measurement priority, leave the watch on your wrist or in any other location where the
temperature of the watch is kept constant.
• To give temperature measurement priority, remove the watch from your wrist and allow it to hang freely
from your bag or in another location where it is not exposed to direct sunlight. Note that removing the
watch from your wrist can affect pressure sensor readings momentarily.

Viewing Altitude Records
Use the Data Recall Mode to view manual saved altitude readings and automatically saved high altitude,
low altitude, total ascent, and total descent values. Altitude data records are created and saved in the
Altimeter Mode.
To view altitude records
1. Use
D
to select the Data Recall Mode (
REC
) as shown on page E-24.
• About one second after REC appears on the display, the display
will change to show the fi rst record of the memory area you were
viewing when you last exited the Data Recall Mode.
2. Use
B
to select the memory area you want.

Auto saved values
• Records of manually saved altitude values (REC 1 through REC 14) and the MAX and MIN
automatically saved altitude values include the date (month, day) and time (hour, minute) that the
data was recorded.

• Records of the ASC and DSC automatically save altitude values include the date (month, day) and
year that the data was recorded.
• For detailed information about auto saved values, see “Auto Save Values” (page E-63).
4. After you are fi nished viewing data, use
D
to exit the Data Recall Mode.
• ---- will be displayed if data has been deleted or if there is no corresponding data due to error, etc.
In such cases, total ascent (ASC) and total descent (DSC) values will show zero.
• When the total ascent (ASC) or total descent (DSC) exceeds 99,995 meters (or 327,980 feet), the
applicable value will restart from zero.
• When the total ascent (ASC) or total descent (DSC) value
becomes fi ve digits long, the rightmost (ones) digit is shown in the
lower right of the display. The nearby illustration shows the display
when the value of ASC-1 is 99995 meters.

To clear the contents of a specifi c memory area
1. Use
D
to enter the Data Recall Mode.
2. Use
B
to select the memory area you want to clear.
• Note that the contents of the memory area you select will be
deleted as soon as you perform step 3 below. The clear operation
cannot be undone, so double check to make sure you really want
to delete the contents of the memory area you select here.
3. Hold down
E
until CLR Hold appears on the display and then Hold
disappears.
• This deletes the record you displayed in step 2.
• Release
E
after CLR appears on the display.

Viewing Tide and Moon Data
The Tide/Moon Data Mode shows tide and Moon information for the Home City you selected in the
Timekeeping Mode.
• See “Moon Phase Indicator” (page E-82) for information about the moon phase indicator and “Tide
Graph” (page E-84) for information about the tide graph.
• All of the operations in this section are performed in the Tide/Moon Data Mode (page E-24).
Note
• It takes about two seconds to calculate tide graph data. You will not be able to display a setting screen
while data calculation is in progress.
• Moon age is calculated to an accuracy of ±1 day.
Tide Data
The Tide Graph that appears fi rst when you enter the Tide/Moon Data Mode shows the data at 6:00 a.m.
for your currently selected Home City (tide site) on the current date, according to the Timekeeping Mode.
From there you can specify another time on the same date.
• If the tide data is not correct, check your Timekeeping Mode settings and correct them if necessary.
• If you feel that the information shown by the Tide Graph is different from actual tide conditions, you
need to adjust the high tide time. See “Adjusting the High Tide Time” (page E-80) for more information.
E-78
Moon Data
The Moon phase and Moon age information that appears fi rst when you enter the Tide/Moon Data Mode
shows the data at noon for your currently selected Home City on the current date, according to the
Timekeeping Mode. After that you can specify another date to view data.
• If the Moon data is not correct, check your Timekeeping Mode settings and correct them if necessary.
• If the Moon phase indicator shows a phase that is a mirror image of the actual Moon phase in your
area, you can use the procedure under “Reversing the Displayed Moon Phase” (page E-81) to change
it.
To enter the Tide/Moon Data Mode
Use
D
to select the Tide/Moon Data Mode (
TIDE
) as shown on page
E-24.
• After about one second,
TIDE
appears on the display, the display will
change to show the moon age.
E-79
To view Moon Data for a particular date, or Tide Data for a particular date and time
1. In the Tide/Moon Data Mode, use
A
(+) and
C
(–) to scroll to the
date whose tide and Moon information you want to view.
• After you select a date, the watch starts to calculate Moon and tide
data for the date you selected. The calculation operation takes
about two seconds, and is indicated by movement in the Moon
Phase indicator and the Tide Graph on the display. You can use
A
and
C
to change to another date while a calculation operation
is in progress.
• After calculation is complete, the Moon information (Moon age and
phase) and tide information (current tide level and tide range) will
be displayed for the date you selected.
2. While the Moon information (Moon age and phase) and tide information
(tide level and tide range for the current date) are displayed, you can
press
B
(+) to advance the displayed tide range by one hour.
• You also can use
A
(+) and
C
(–) to change the date.
• Update of the Moon Phase indicator and the Tide Graph is
stopped while any of the following is occurring.
During button operation
While an alarm is sounding
While a countdown beeper is sounding
During display illumination
During Auto Receive of a time calibration signal
During a 2-hour barometric pressure reading operation
