• 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.

and the watch's altitude differential value, advance towards your

destination.
• 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.
Altitude Altitude
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 air-pressure-to-altitude
conversion calculation accordingly.

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
take an altimeter reading" (page E-44) for details.
2. Hold down
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.

Confi guring the Altitude Differential Scale
You can select either of the two altitude differential scale options described below.
To specify this:
Scale step: 5 meters (20 feet) per second mark
Scale range: ±100 meters (± 400 feet)
Scale step: 50 meters (200 feet) per second mark
Scale range: ±1000 meters (± 4000 feet)
• Altitude differential is always calculated in meters, even when feet is selected as the altitude
measurement unit.
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
on the digital display.
Destination Destination
• If an altitude reading is not displayed, press

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

Types of Altitude Data
The watch maintains two types of altitude data in its memory: manual save records and auto save values
(low altitude, high altitude, cumulative ascent, cumulate descent).
• Use the Data Recall Mode to view data stored in memory. See "Viewing Altitude Records" (page E-63)
for details.
Auto Save Values
While the altitude auto measurement method is being used (page E-46), the watch automatically stores
high altitude ( HI), low altitude ( LO), cumulative ascent ( ASC), and cumulative descent ( DSC) values.
• These values are checked and updated automatically by the watch as altitude auto measurements are
taken.
How the high altitude and low altitude values are updated
While the watch is in the Altimeter Mode, altitude readings are taken automatically at the interval specifi ed
by the altitude auto measurement method (page E-46). With each reading, the watch compares the
current reading against the HI and LO values. It will replace the HI value if the current reading is greater
than HI, or the LO value if the current reading is less than LO.
