7. At the desired altitude, either PRESS the [Mode] button to accept the changes and return to the main mode

or PRESS the [Select] button to move to the next setting. Located in Field 1, the text INT and located in

Field 2 the time interval will begin to flash (Fig. 4).

8. PRESS either the [+] or the [-] button to scroll through the intervals. There are four time intervals 20 seconds,

1 minute, 10 minute or 60 minute.

Recommended interval to use:

Activity Interval

Skiing 20 sec or 1 minute

Biking 20 sec or 1 minute

Hiking 10 Minute

Mountaineering 10 minute or 60 minute

Note: In selecting the interval, the user chooses a) the time period for recording the altitude, the vertical ascent/

descent rate as well as the current time to be stored into the logbook and b) the timeout or maximum recording

time of a logbook. The shorter the interval the more accurate the information due to the fact the sampling rate

is faster. Timeouts are discussed on page 25.

9. At the desired interval, PRESS the [Mode] button to accept the changes and exit the setup program.

Once the user completes the process in setting the reference altitude of the current location to the known

altitude, the Wristop Computer will also correct the sea level pressure, and therefore, it will not be necessary for

this function to be set.

Note: If the user does not press any button for 1 minute in the setup mode, the display will automatically

exit setup.

Note: A 10-minute recording interval means that the Wristop Computer records data every 10 minutes.
