SWITCHING GAS MIXES (NORM only)
During NORM Dives, the Elite T3 can be manually switched from GAS 1 to GAS 2 to GAS
3, changing FO2 displays and calculations from the FO2 value set for GAS 1 to the FO2
value set for GAS 2 to the FO2 value set for GAS 3, and if TMTs are used, changing
Pressure related displays and calculations from TMT 1 (Transmitter 1) to TMT 2 to TMT 3.
NOTE: Switching the Elite T3 from one GAS to another cannot be
performed while on the surface, during dives when TMT 2-3 USE is set
for Buddy Pressure Check, or when operating in GAUG Mode.
Every dive begins with GAS 1. 10 minutes after surfacing from a
multiple gas dive, the Elite T3's operation defaults to the GAS 1 FO2.
Access to NORM DIVE Gas Switching screens can only be accomplished during the time
that a NORM DIVE MAIN screen is being displayed and cannot be performed during the
time that an Alarm is sounding.
NOTE: If a Switch to a new Gas Mix would
expose the diver to a prohibitive PO2 level of
1.60 ATA or greater, the Audible Alarm will
sound, the red LED will flash, and the message
DONT > SWCH will scroll at the top of the display
(Fig. 87) until acknowledged by depressing the A
button for 2 seconds.
