Explanation
If the DZ landing elevation differs from that of the aircraft take off elevation, offset
the VISO II prior to entering the aircraft as follows:
VISO II Settings
Altitude Offset
Press and hold or to offset the current altitude.
Press to save setting and enter the Dive Type selector.
Note: When performing altitude offset, the VISO II enters Jump Mode and the altitude
offset will be retained for 14 hours, if no jump is made. After 14 hours the VISO II
recalibrates to the field elevation where it is currently located. The selected Offset Altitude
remains displayed in the Main Window after VISO II goes out of ACCESS. When offsetting
to a negative altitude the display will flash between minus (-) and the selected negative
altitude. The altitude offset is not retained when the VISO II is powered OFF.

VISO II Settings
Press or to toggle between Mph/Kmh.
The active selection flashes.
Press to save setting and enter Altitude Offset.
Note: Jump data is continuously stored in both Mph and Kmh.
At any time stored information may be displayed in either unit
of measurement by selecting the respective mode.

Press to scroll forward through the dive type list.
Press to scroll backward through the dive type list.
Press to save setting and enter the TAS/SAS Selector.
0 = ---- (blank, factory default parameters)
1 = SLO (Slow) *
2 = STU (Student) **
* Dive Type, 1: SLO (Slow)
In SLO the exit fall rate and deployment calculation parameters are changed to fit
very slow falling types of dives, like wing suit dives, etc.
** Dive Type, 2: STU (Student)
In STU the descent rate parameters are changed to allow detection of short freefalls,
(2 sec).

The Dive Type mode can be used to change parameters when the VISO II detects
freefall exit and canopy deployment.

Explanation
True Airspeed (TAS) and Skydiver’s Airspeed (SAS) are two methods of calculating
the airspeed of a moving/flying/falling object.
TAS is a term used in aviation: It is the speed of an object relative to the surround-
ing air, regardless of the altitude.
SAS is a new concept developed by LARSEN & BRUSGAARD: SAS is the speed of a
skydiver calculated from measurements of air pressure and temperature and con-
verted to a fixed air pressure (875.3 mb) and a fixed temperature (+7.080C) which
corresponds to 4,000 feet ASL.
