Explanation
The VISO continuously adjusts itself to the local elevation and displays 0 FT (MT)
in the Altitude/Speed area. If the Altitude/Speed area does not display “0” prior to
jumping, the unit has not yet adjusted itself to the local elevation and it must be
manually zeroed.
To manually zero the unit either perform reset or turn the unit OFF and then ON.
(Perform reset, see page 55)
(Turn OFF the unit, see page 37)
