GAS/TRANSMITTER SWITCHES
!
WARNINGS:
• Historically, many accidents and near misses have occurred by switching to the wrong gas at the
wrong depth. DO NOT attempt gas switch decompression dives without proper education and
training to do so from an internationally recognized training agency.
• Diving deeper than 39 m (130 ft), will greatly increase your risk of decompression sickness.
• Decompression diving is inherently hazardous and greatly increases your risk of decompression
sickness, even when performed according to the dive computer's calculations.
• Using an i750TC is no guarantee of avoiding decompression sickness.
• The i750TC enters Violation Mode when a situation exceeds its capacity to predict an ascent
procedure. These dives represent gross excursions into decompression that are beyond the
boundaries and spirit of the i750TC's design. If you are following these dive profiles, Aqua Lung
advises that you should not use an i750TC.
• If you exceed certain limits, the i750TC will not be able to help you get safely back to the surface.
These situations exceed tested limits and can result in loss of some functions for 24 hours after the
dive in which a violation occurred.
OVERVIEW
• All dives begin with GAS 1 and TMT 1.
• The GAS and TMT default to # 1 after 10 minutes on the surface.
• Gas switches can only be made when a Dive Main screen is displayed.
• Gases cannot be switched while on the surface.
• The Gas Switch Menu cannot be accessed during the sounding of alarms.
• If an alarm strikes while in the Gas Switch Menu, the switch operation is terminated (reverting to the Dive Main
screen.
