To select the altitude screen format
1. Enter the Altimeter Mode (page E-27).
2. Use E to toggle the setting between the two screens.
Selecting the Altitude Auto Reading Interval
You can select either of the following two altitude auto reading intervals.
- 0’05: Readings at one-second intervals for the first three minutes, and then every five seconds for approximately the next hour
- 2’00: Readings at one-second intervals for the first three minutes, and then every two minutes for approximately the next 12 hours
Note
*If you do not perform any button operation while in the Altimeter Mode, the watch will return to the Timekeeping Mode automatically after 12 hours (altitude auto reading interval: 2’00) or after one hour (altitude auto reading interval: 0’05).
To select the altitude auto reading interval
1. In the Altimeter Mode, hold down E for at least two seconds. You can release E after ALTI appears.
• The current altitude reading value will appear at this time.
2. Press D to display the current altitude auto reading interval setting.
• The display will show 0’05 or 2’00.
3. Press A to toggle the altitude auto reading interval setting between 0’05 and 2’00.
4. Press E to exit the setting screen.
Taking Altitude Readings
Use the procedure below to take basic altitude readings.
• See “Using Reference Altitude Values” (page E-44) for information about how to make altimeter readings more accurate.
• See “How does the altimeter work?” (page E-48) for information about how the watch measures altitude.
