Battery Replacements
The Wristop Computer operates on a three-volt lithium cell Type: CR 2430. The maximum life expectancy
is approximately 12-18 months.
A low battery-warning indicator is activated when 5-15 percent of the battery capacity is still available.
When this occurs we recommend replacement of the battery.
Extreme cold weather will activate the low battery-warning indicator. Though the indicator is activated,
the battery may not need to be replaced due to this condition. In temperatures above 10OC (50OF) and
the low battery warning indicator is activated, the battery will need to be replaced.
Note: Heavy use of the electroluminescent backlight, altimeter, and compass will significantly reduce
the life of the battery.
To replace the battery:
1. turn the Wristop Computer to view the backside;
2. insert a coin in the coin slot located on the battery compartment cover;
3. turn the coin counterclockwise to the open position marked on the back of the case;
4. remove the battery compartment cover;
5. remove the old cell from the battery compartment and ensure the o-ring and all surfaces are
clean and dry. Do not stretch the o-ring;
6. place the new cell into the battery compartment (negative side down, positive side up);
7. ensure that the o-ring is in its place to keep the Wristop Computer waterproof. Place the battery
compartment cover back onto the backside of the Wristop Computer;
8. insert a coin back into the coin slot; and
9. turn the coin clockwise to the close position marked on the back of the case.
Note: Battery replacement should be performed with extreme care so as to ensure the Wristop
Computer continues to remain waterproof.It is the operators responsibility to take due care to ensure
that the Wristop Computer remains waterproof.
After every battery replacement, it is necessary to calibrate the magnetic sensor. Details on performing
this process are found in Calibrating the Compass section of this manual.

CHAPTER 4 ALTIMETER MODE
Note: This feature applies to the Altimax, Vector and X-Lander.
The Altimeter function provides the user with:
an adjustable unit of measure either meter or feet: meter range -500 to 9,000; ft range -1,600 to 29,500;
a resolution of 5m or 10ft;
a display up-date on the rate of vertical movement in intervals of 1 second for 3 minutes, then every 10
seconds or less;
an automatic 24-hour memory in one hour intervals showing altitude and vertical ascent/descent rate;
and
a logbook, recording approximately 3800 sets of data
(one set = altitude, vertical ascent/descent rate and time).
To view and use the Altimeter function:
Check the Mode Indicator Bar. If the mode arrow is not on ALTI, PRESS the [Mode] button until the arrow
is directly below ALTI on the bar.
In the ALTIMETER mode:
Field 1 displays the vertical ascent or descent rate;
Field 2 displays the current altitude in increments of 5 meters or 10 feet (depending on the unit of
measure selected); and
Field 3 displays the current time.
The Outer Circumference graphically displays the altitude in hundreds of meters or feet over a full
thousand where one complete circle is equivalent to 1000.
IMPORTANT NOTE: IN ORDER TO SET THE ALTITUDE IN THE ALTIMETER MODE, THE ALTITUDE MUST BE
KNOWN. THAT INFORMATION CAN BE FOUND BY UTILIZING A TOPOGRAPHICAL MAP, IDENTIFYING THE
CURRENT LOCATION WITH THE ASSOCIATED ALTITUDE MARKED. THE USER CAN PROCEED AND FOLLOW
THE INSTRUCTIONS, SETTING THE ALTIMETER, PROVIDED IN THE SECTION BELOW.
DETAILS REGARDING THE EFFECT OF AIR TEMPERATURE ON ALTITUDE MEASUREMENT ARE SHOWN ON
PAGE 48 OF THIS MANUAL.
Page 28
28
IF THE ALTITUDE IS NOT KNOWN, THE USER CAN SET THE SEA LEVEL PRESSURE IN
THE BAROMETRIC MODE (REFER TO PAGE 37, SETTING THE SEA LEVEL PRESSURE).
SETTING THE SEA LEVEL PRESSURE WILL ADJUST THE ALTIMETER TO THE CURRENT
ALTITUDE WITHIN SOME TEN METERS OR FEW HUNDRED FEET.
INFORMATION ON THE CURRENT SEA LEVEL PRESSURE CAN BE OBTAINED THROUGH NEWSPAPERS, LOCAL
NEWS AND RADIO WEATHER REPORTS, THE LOCAL AIRPORT FACILITY OR THROUGH THE INTERNET UNDER
LOCAL WEATHER.
Setting the Altimeter
In setting the Altimeter, there are three processes that can be performed:
the Reference Altitude (known altitude at the current location),
the Altitude Alarm (signifies the user when a certain altitude, programmed, is reached), and
the Logbook Recording Interval (allows the user to view the altitude and average rate of vertical
movement within a chosen interval of time).
To begin:
1. PRESS the [Select] button and hold for 2 seconds. Located in Field 1 is the text RE (indicating reference
altitude), located in Field 2, the current altitude will begin to flash.
2. PRESS the [+] button to scroll the altitude upward or
PRESS the [-] button to scroll the altitude downwards.
3. At the desired reference 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 ON
or OFF will begin to flash.
4. PRESS either the [+] or the [-] button to toggle between the ON and OFF for the Altitude Alarm.
5. At the desired setting, PRESS the [Select] button to move to the next setting. Located in the center of
Field 2, the alarm altitude will begin to flash.
6. PRESS the [+] button to scroll the altitude upward or
PRESS the [-] button to scroll the altitude downwards.
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.
Page 29

Hiking 10 Minute
Climbing 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 3-8.
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.

How long will the battery last?
All users employ the product in different ways. Battery life depends mainly on how much the backlight,
the compass and the logbook are used. The low-battery warning symbol appears on the display when
5 to 15 percent of battery capacity remains. This should give the user plenty of time to safely change
the battery.
What do the segments on the circumference mean?
In the Altimeter mode, one full circle equals 1,000 meters or 1,000 feet, therefore the segments on the
circumference graphically show the user the altitude over a full thousand. When using the difference
measurement function of the altimeter, the segments indicate the vertical difference in the elevation
over a full thousand either to the right if youre ascending or to the left if youre descending.
In the Barometer mode, one full circle equals 100 mbar or 1 inHg, and the segments indicate the
pressure over a full hundred mbar or over a full inHg. When using the difference measurement function
of the barometer, the segments indicate the change in atmospheric pressure either to the right if the
pressure has risen or to the left if the pressure has dropped.
In the main Compass mode, the segments indicate the North, i.e. the one segment indicates North and
the three segments point South. If you have set the compass to track a certain bearing, the segments
on the circumference indicate the difference between the direction in which you want to go and your
actual bearing.
Why do the segments on the circumference go to the left (counterclockwise)?
Normally, they always go to the right (clockwise) from the 12-noon position.
You are in the difference measurement mode and your unit is showing a decreasing value. In normal
Page 44
44
mode, the segment display increases clockwise, but if you are in a mode that shows you differences
(such as vertical ascent/descent), all decreasing values go counterclockwise from the center position, and
all increasing values go clockwise. So, it is minus to the left (counterclockwise), and plus to the right
(clockwise).
Why are there two symbols above the Mode Indicator Bar and what do they
mean?
The left-hand symbol indicates that the altitude alarm is activated and the right-hand symbol indicates
that one, two, or three daily alarms are activated.
TIME
Why do the segments on the circumference increase and decrease when I am in
the Time mode?
The main function of the segments is related to the Compass mode, where a division into 36 segments is
necessary due to the 360-degree scale of a compass. In the Time mode, the segments show the
advancement of seconds. Because the number of seconds differs from the number of degrees, it is
impossible for the segments to be consecutively lit up; they now light up or extinguish, thereby marking
the passing of every second.
What is the longest time I can set in the timer?
The maximum range of the countdown timer is 23 hours 59 minutes and 59 seconds.
ALTIMETER
How do you clear the logbook?
The logbook is self-erasing and cannot be cleared by the user.
How does the logbook self-erase?
The logbook is circular and will start erasing itself when all the memory places are filled. There are
approx. 3,800 memory places, each of which contain the altitude as well as the ascent/descent rate at
that time (according to the chosen interval, 20 seconds, 1 minute, 10 or 60 minutes).
Page 45
45
When all the memory places are filled, the logbook starts recording new logs on top of the oldest
recordings. This is what is meant when we say the logbook is self-erasing.
You can clear the history of the logbook; i.e. where you get the cumulative ascent and descent information
based on the logs recorded into the logbook.
How many logbooks can you record?
The number of logs you can record into the logbook depends on the chosen interval and the length of
each log. For example, if your interval is 1 minute, you can get a total of 3,800 minutes of logs into the
logbook. This equals 2.64 days if the recording is continuous (24 hours = 1,440 minutes; 3,800/1,440=2.64).
To avoid excessive battery drain, the recording is not continuous. The recording functions have certain
timeouts (i.e. the recording will be turned off automatically after a certain time). The timeouts are
shorter for the faster interval and longer for the slower interval.
What is the duration readout?
The duration readout tells you how many hours and/or minutes the event recorded into the logbook
lasted. For example, if youre hiking from 1 p.m. to 6 p.m. and the logbook is on during this time, the
readout would show a duration of 05:00 hours.
What is the maximum capacity of total vertical ascent or descent feet/meters in
the logbook history?
The maximum figure that can be shown on the display is 29,999.999 representing feet or meters depending
on the unit of measurement set. This should be enough for most users: 29,999.999 meters is roughly
three-quarters around the globe.
If hiking from a level of 5,000 ft down hill to 3,000 ft and then back up to 8,000
feet, how is the Vector going to read this or average it out?
There are several answers to this question related to different situations.
First, if you mean will Wristop Computer show accurate altitude information when ascending back to
8,000 ft after having descended to 3,000 ft from 5,000 ft, the answer is yes if the barometric pressure
hasnt been affected by weather changes. Since the altitude is shown based on the atmospheric pressure
Page 46
46
reading it will be affected by pressure changes. But if the conditions are the same, and the reference
altitude is set, the unit will show quite accurate readings.
Second, if what you mean is how the Wristop Computer calculates the information shown in the logbook,
this is what it does: for the total ascent during the log (the logbook recording has been activated by the
user when starting out) it calculates the ascent from 3,000 ft to 8,000 ft, i.e. total ascent has been
5,000ft. For the descent it calculates the descent from 5,000 ft to 3,000 ft, i.e. total descent 2,000 ft.
Third, if thinking about the difference measurement function and how this is affected by the example
situation, the Wristop Computer will show you the absolute difference between 5,000 ft and 8,000 ft
(beginning and end). The fact that youve been down to 3,000 ft in-between does not have an impact on
the absolute vertical altitude difference between starting point and finish.
Last, the automatic 24-hour memory will show this information in the following way: Say you are
starting out at 5,000 ft at noon, and then it takes you 2 hours to descend to 3,000 ft, and another five
hours to reach 8,000 ft. The scrollable displays in the 24-hour memory shows you the altitude 5,000 ft at
12:00 am, e.g.4,000 ft at 1 p.m., 3,000 ft at 2 p.m., e.g. 4,000 ft 3 p.m., 5,000 ft at 4 p.m., 6,000 ft at 5
p.m., 7,000 ft at 6 p.m. and then 8,000 ft at 7 p.m.
These are the different cases in which the example situation will affect the readings of the Wristop
Computer. Most important to remember is to ALWAYS set the known reference altitude into the Wristop
Computer. This is the only way to get accurate altitude readings.
Why does the vertical ascent/descent measurement show different readings even
though I am inside and staying in the same room?
The resolution of the vertical ascent/descent rate is 1 m/1 ft whereas the resolution of the altitude
display is 5 m/10 ft, which means that the ascent/descent rate can show movement even though you
remain at the same altitude. This is caused by changes in pressure or even vertical movement within the
5 m/10 ft resolution range.
Indoors, even small, unnoticeable air currents cause changes in air pressure. For example, if you have a
window open at the other end of your house, the air current may affect a room at the other end of the
building so little that you do not notice it, but the sensors of the Wristop Computer do. Because the
Wristop Computer measures ascent and descent based on changes in air pressure, it interprets these
changes as vertical movement.

BAROMETER
What is the little box on the top left of the display?
It is the barometric trend indicator that shows the general direction of weather changes. The display is
based on barometer measurements for the last 6 hours.
Does the Wristop Computer show future trends in weather conditions?
No, the Wristop Computer continually accumulates data on barometric pressure existent within a 3 to 6
hour window and displays general barometric trends in weather based on the accumulated data.
What does absolute pressure and relative pressure mean?
Absolute pressure is the actual pressure in any location at any given time. Relative pressure on the other
hand equals the corresponding pressure at sea level for a certain altitude that you are at. For example,
if you are at an altitude of 1,000 m/3,300 ft the absolute pressure normally is around 900 mbar/26.60
inHg. The relative pressure at sea level would then be around 1,013 mbar/29.90 inHg.
What is temperature compensation?
When the unit is temperature compensated, the altitude measurement of the unit is not affected by
the temperature of the unit itself. The unit can be worn on your wrist or placed on a table it will in
either case give you the proper altitude reading providing the weather conditions have not changed.
All Suunto Wristop Computers are temperature compensated within the range 5 to 140 ° F / - 20 to
+60 ° C.
COMPASS
What is the purpose of the rotating outer bezel?
The purpose of the rotating bezel is that people can use the instrument as a regular base plate compass
if they want to, and use the bezel to e.g. indicate North when in the bearing tracking mode or leaving
the compass display for another mode.
Also, it can be used to manually follow your vertical progress by using the North indicator on the bezel
to mark the altitude from where you want to follow your progress (i.e. a zero point). You could also
Page 48
48
mark a certain altitude, which is graphically shown by the segments on the circumference, to get an
intermediate difference measurement. However, the bezel is mainly related to the compass function.
Where do I find the correct declination for my area so I can set my Wristop
Computer?
Local declination, either E or W, is usually marked on maps with either one-degree or half-degree
accuracy.
EFFECT OF AIR TEMPERATURE ON ALTITUDE MEASUREMENT
The atmospheric pressure means the weight of air mass above the observer: at a higher altitude there
is less air than at a lower altitude. The principle of an altimeter is to measure the different air
pressure between different altitudes.
The air weight is affected by the outside temperature. Consequently the air pressure difference
between two altitudes is also dependant on temperature.
The altitude calculation of Wristop Computer is based on the air pressure at certain normal temperatures.
Each altitude has a definitive normal temperature. The normal temperatures at each altitude are
presented in table 1.

Table 1. Normal temperatures corresponding to different altitudes
Now the altitude measurement error caused by an abnormal temperature gradient can be approximated
as follows. If the sum of the temperature offsets from the normal temperatures
determined at two different altitudes is 1 ºC, the altitude difference calculated by
Wristop Computer is 0.2% off the real altitude difference (When using imperial units the
offset factor is 0.11% / 1 ºF). This is because the real temperatures are not always the same as the
normal temperatures. A higher than normal temperature causes the calculated altitude difference to
be smaller than the real altitude difference (your mountain ascent was actually higher). Consequently,
a lower than normal temperature causes the calculated altitude difference to be larger than the real
altitude difference (you did not ascend quite as high as displayed).
Page 50

Table 2 shows an example in which the temperature offsets are positive. In this example, the reference
altitude is set at 1000 m. At 3000 m the altitude difference is 2000 m and Wristop Computer shows 80
m too little (20 ºC * 2000 m * 0.002/ºC = 80 m). Your actual altitude is thus 3080 m.
Lower point Higher point
Set reference altitude (real altitude) 1000 m
Displayed altitude 3000 m
Real outside temperature +17.5 ºC +6.5 ºC
Normal (table) temperature +8.5 ºC -4.5 ºC
Temperature offset (= real - normal) +9 ºC +11 ºC
Sum of temperature offsets +9 ºC + +11 ºC = 20 ºC
Table 2. Example using meters and Celsius
Table 3 shows an example in which the temperature offsets are negative This time imperial units are
used. The reference altitude is set at 3280 feet. At 9840 feet the altitude difference is 6560 feet and
Wristop Computer shows 100 feet too much (-14 ºF * 6560 ft * 0.0011/ºF = -100 ft). Your actual altitude
is thus 9740 ft.
Lower point Higher point
Set reference altitude (real altitude) 3280 ft
Displayed altitude 9840 ft
Real outside temperature +36.3 ºF +18.9 ºF
Normal (table) temperature +47.3 ºF +23.9 ºF
Temperature difference (= real - normal) -9 ºF -5 ºF
Sum of temperature offsets -9 ºF + -5 ºF = -14 ºF
