Setting the altimeter 
Press the Victorinox emblem for 4 seconds until 
the display flashes. Now release the Victorinox 
emblem again. You have changed over to the 
altimeter setting mode. 
The arrow shows the present adjustment direction. The changeover is automatic. 
If the Victorinox emblem is pressed for a longer 
period (at least 6 seconds), the adjusting speed 
is increased (20 digits/s). 
Brief pressure on the Victorinox emblem changes 
the display by 1 digit (meter). To increase the 
value which is shown, press the Victorinox 
emblem repeatedly while the arrow points upwards. When the correct altitude is shown on the 
display, wait for 10 seconds until the system has 
accepted the entry made by you. 
The display then changes over to the "Weather 
correction mode". When the Victorinox emblem is 
pressed briefly, the correction setting can be 
altered in the sequence "Stnd", "Cold", "Hot". 
Stnd standard temperature for a particular 
altitude (tolerance ±5°C) 
Cold colder than standard (difference greater 
than 5°C) 
Hot  warmer than standard (difference greater 
than 5°C) 
(Standard values see table on page 4) 
If the button is not pressed within 4 seconds, the 
"Weather correction mode" is quit automatically 
and the new setting accepted. 
Warning!!! 
To extend the battery life many times over, 
the altitude display has a built-in delay, 
therefore, the altimeter must not be used 
during sky diving or other similar sports. 
Altitude error / Impact of atmospheric pressure fluctuations 
A change in the weather causes the barometric 
pressure to alter; this in turn means that the 
displayed altitude differs from the effective 
altitude. The error can be eliminated by adjusting 
the altitude. Even on a stable day, temperaturerelated air pressure fluctuations of ±1 mbar may 
occur; this is equivalent to an altitude error of  
±8 meters. Under normal weather variations, an 
altitude difference of 40 – 50 m may easily occur 
after a single day. If the pressure difference is 
great (storm front), a change of up to 100 m is 
also realistic. Over a two-day period, a difference 
of 200 – 250 m may occur in the event of extreme weather changes. 
1 mbar > approx. 8 m 
(or approx. 16 m at 5'500 m above sea level) 
1 hPa = 1 mbar = 0.001 bar = 0.75 mmHg 
Because of these air pressure fluctuations, an 
altimeter must always be readjusted before use. 
Set the altitude on a daily basis if you are hiking 
or climbing or wish to take account of weather 
changes. This means that the altimeter must be 
reset at a known altitude (e.g. at home, at a 
railway station, mountain hut etc.).
