120
When the Conservative Factor feature is set ON, allowable dive times are calculated
based upon the next higher 3,000 foot (915 meter) Altitude. All adjustments for Alti-
tudes greater than 11,000 feet (3,355 meters) are then made to allowable dive times
for 14,000 feet (4,270 meters). If the Conservative Factor is set ON while at Sea Level,
calculations are based upon an Altitude of 6,000 feet.
The ZEN will not function as a Dive Computer above 14,000 feet (4,270 meters).
