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.

 

Reading time

To view altitude records

 

1.

Use D to select the Data Recall Mode (REC) as shown on page E-24.

 

(Hour : minute)

 

 

• About one second after REC appears on the display, the display

Record number

 

 

 

 

will change to show the first record of the memory area you were

 

 

 

 

 

viewing when you last exited the Data Recall Mode.

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 finished 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 five 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-1is 99995 meters.

To clear the contents of a specific 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 first 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.

Moon Data

To view Moon Data for a particular date, or Tide Data for a particular date and time

The Moon phase and Moon age information that appears first 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

Moon phase

Moon age

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

• After about one second, TIDE appears on the display, the display will change to show the moon age.

Current tide range

Current tide level

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
