WARNING!
FAILURE TO FOLLOW ALL WARNINGS, INSTRUCTIONS, AND REQUIRED PROCEDURES MAY
RESULT IN SERIOUS INJURY AND DEATH.
Always ensure your altimeter is adjusted to zero prior to jumping to account for any
changes in barometric pressure.

Larsen & Brusgaard operates a policy of continuous development.
Therefore, we reserve the right to make changes and improvements to any of the
products described in this guide without prior notice.
Altimeters may give erroneous readings if you are tumbling or the altimeter is in a
burble (wake), such as when sit flying or sky surfing. Chest mount altimeters are more
vulnerable to this problem. If you are in doubt about how this limitation affects your
skydiving, consult a licensed instructor.
DO NOT use this equipment unless you are on, or have passed an approved skydiving
course.
Use the VISO™ at your own risk.

freefall parameters. Please read ALL of the instructions prior to actual skydiving use.
The VISO comprises three instruments:
1 Digital Alti-Meter
Stores detailed altitude information about the last jump for later review
2 Digital Speed-Meter
Stores detailed speed information about the last jump for later review
3 Jump Counter
Electronic logbook, storing and displaying information about the last 200 jumps.
- Can be used as an aid to track the amount of jumps performed on a rig.
- Can be reset at any time, but time and date for the last reset remains stored and
cannot be erased.

• Digital Alti-Meter or Speed-Meter
• Electroluminescent backlight for night jumping. Can remain ON for several hours
• Automatic calibration to local elevation
• LCD screen for easy and intuitive operation and information review
• Logbook with playback of altitude/speed profile for the last jump
• Operational at sub-zero temperatures
• Switches OFF automatically after 14 hours
Software & functions
• Stores up to 10 minutes of profile data from last jump

• Records and displays jump information about the last 200 jumps including exit
altitude, deployment altitude, freefall time, max. speed in freefall and max. speed
under canopy
• Choice of readings in feet or meter and mph or kmh

Power ON
The VISO has been powered OFF prior to shipping from our factory. To turn the
power ON, press and hold any key until the VISO beeps, then release the button.
Auto OFF
The VISO automatically switches OFF 14 hours after the last jump or 14 hours after
the last pressing of any key, whichever comes first.
The VISO runs a self-test and
displays all icons
It then displays the firmware
version number together with
a factory reference number...
...and switches to a screen
configuration referred to as
the “Main Window”.

This represents the starting point for all further actions and subsequent displays.

Explanation
The Main Window is the default window which displays current time, battery status
and either Altitude or Speed.
Alti-Meter Mode
When the VISO is set to Alti-Meter mode, the
“ALTI” and “Feet/Meter” icons are ON.
The VISO will display the altitude during climb, in
freefall and under canopy.
The date/time information switches OFF during
freefall and under canopy.
(When preset, press to view the current date).
Alti-Meter Displays
In Alti-Meter mode the LCD may show 3 different displays, depending on what
altitude value is shown.
If the altitude is below 1000 the altitude is displayed as
normal. Altitude resolution is in 10 feet (5 meter) incre-
ments.
If the altitude is 1000-9999, the altitude is displayed as
tens of feet or meter. Altitude resolution is in 10 feet
(10 meter) increments

If the altitude is 10000 or higher, the altitude is displayed as
hundreds of feet or meter. Altitude resolution is in 100 feet
(100 meter) increments.
Speed-Meter Mode
When the VISO is set to Speed-Meter mode, the “ALTI”,
“Feet/Meter”, “Mph/Kmh” and “TAS/SAS” icons are ON.
Note: The VISO will display the altitude during climb and
switch to Speed-Meter during the freefall and under canopy.
Date/Time area switches OFF during the freefall and under
canopy.
Speed-Meter Display during the freefall
Speed resolution is in 1 Mph (1 Kmh) increments.
Important Notice about Speed Recordings
Experience has shown that when mounting the VISO on the hand or belly, different
air pressures induced by hand or body movements may result in incorrect recordings
of speeds.

Road Map
VISO Settings
It is recommended that you first familiarize yourself with the VISO
ROAD MAP which is a very helpful tool when using the VISO for the first time.
The ROAD MAP comprises four areas:
• Backlight Setup Area (see page 39)
• Profile Area (see page 51)
• Setup Area (see page 19)
• Logbook Area (see page 43)
The VISO can be customised to your personal settings. Your settings will be stored
and recalled also after replacing batteries. When you first get the VISO, we recom-
mend you to go through the SETUP Selector to customise the VISO settings.
SETUP Selector
In the Setup Area the following options can be selected:
• Alti-Meter/Speed-Meter
• Feet/Meter when set to Alti-Meter
• Mph/Kmh when set to Speed-Meter
• Altitude offset
• Dive Type
• True Airspeed (TAS) / Skydiver’s Airspeed (SAS)
• Set current year
