Using the Altitude Differential Value
Altitude differential indicated by second hand
In the Altimeter Mode, the part of the watch’s dial from 11 o’clock to 7 o’clock acts as an altitude differential scale. The second hand points to a place on the scale that indicates the difference between the altitude at a start point set by you and the altitude at your current location. The altitude differential indication is updated each time the watch takes an altitude reading.
You can configure the watch so each second mark in the altitude differential scale stands for 5 meters (20 feet) or 50 meters (200 feet). See “Configuring the Altitude Differential Scale” (page
•The second hand will point to OVER or UNDER if the altitude differential is outside the allowable range of the scale.
•The second hand will move to 9 o’clock if a sensor reading could not be taken for some reason or if the reading is outside the allowable range.

Configuring the Altitude Differential Scale
You can select either of the two altitude differential scale options described below.
To specify this: | Select this setting: | |
Scale step: 5 meters (20 feet) per second mark | 100 | |
Scale range: ±100 meters (± 400 feet) | ||
| ||
|
| |
Scale step: 50 meters (200 feet) per second mark | 1000 | |
Scale range: ±1000 meters (± 4000 feet) | ||
| ||
|

•Altitude differential is always calculated in meters, even when feet is selected as the altitude measurement unit.
To change the altitude differential scale step unit
1. In the Altimeter Mode, hold down E until each of the following steps occurs.
• Hold SET appears on the digital display. ➝ Hold SET disappears.
2. Press D twice.
• This will cause either 100 or 1000 to flash on the digital display.
3. Press A to toggle the altitude differential scale step unit between 100 and 1000.
4. Press E to exit the setting screen.
To set the altitude differential start point
In the Altimeter Mode, press E.
• The watch will take an altitude reading and record the result as the current differential start point. At this time, the second hand will point to 0 because that is the current altitude differential.

Using the Altitude Differential Value While Mountain Climbing or Hiking
After you specify the altitude differential start point while mountain climbing or hiking, you easily can measure the change in the altitude between that point and other points along the way.
To use the altitude differential value
1. In the Altimeter Mode, check to make sure that an altitude reading is

2.Use the contour lines on your map to determine the difference in altitude between your current location and your destination.
3.In the Altimeter Mode, press E to specify your current location as the

and the watch’s altitude differential value, advance towards your | |

| • If the map shows a difference of +80 meters between your current |
| location and your destination, you will know that you are |
| approaching your destination when the second hand is pointed |
| at +80 meters. |

Specifying a Reference Altitude Value
The altitude readings produced by this watch are subject to error caused by changes in air pressure. Because of this, we recommend that you update the reference altitude value whenever one is available during your climb. After you specify a reference altitude value, the watch adjusts its

To specify a reference altitude value
1. In the Altimeter Mode, hold down E until each of the following steps occurs.
• Hold SET appears on the digital display. ➝ Hold SET disappears.
2. Press A (+) or C
• Specify a reference altitude value based on accurate altitude information about your current location from a map, etc.
•You can set the reference altitude value within the range of
•Pressing A and C at the same time returns to OFF (no reference altitude value), so the watch performs air pressure to altitude conversions based on preset data only.
3.Press E to exit the setting screen.
Types of Altitude Data
The watch can maintain two types of altitude data in its memory: manual save records, and auto save values (low altitude, high altitude, cumulative ascent, cumulative descent).
•Use the Data Recall Mode to view data stored in memory. See “Viewing Altitude Records” (page
Manual Save Records
Any time you perform the procedure below in the Altimeter Mode, the watch will create and store a record with the currently displayed altitude reading, along with the date and time the reading was taken. There is enough memory to store up to 14 manual save records, which are numbered from REC01 through REC14.
To create a manual save record
1. In the Altimeter Mode, check to make sure that an altitude reading is on the digital display.
•If an altitude reading is not displayed, press A to take one. See “To
take an altimeter reading” (page
2. Hold down A until Hold REC appears on the digital display and then changes to REC.
•This will save the currently displayed altitude reading in a manual save record, along with the measurement time and date.
•The watch will return to the Altimeter Mode screen automatically after the save operation is complete.
•There is enough memory to store up to 14 manual save records. If there are already 14 manual save records in memory, the above operation will cause the oldest record to be deleted automatically to make room for the new one.
