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.
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 II™ at your own risk.
VISO II is a trademark of Larsen & Brusgaard, Denmark.
Larsen & Brusgaard operates a policy of continuous development.
Therefore, we reserve the right to make changes and improvements to any of the
