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 ying or sky surng. Chest mount altimeters are more
vulnerable to this problem. If you are in doubt about how this limitation aects your
skydiving, consult a licensed instructor.
DO NOT use this equipment unless you are in, or have passed an approved skydiving
course.
Use the VISO II+™ at your own risk.
