Switching.(Norm) - Talis IQ-1201 Benutzerhandbuch

SWITCHING (NORM)
During NORM Dives, the Talis can be manually switched from Gas 1 to Gas 2, changing FO2 displays and calculations.
Switching from one Gas to another cannot be performed while on the surface.
Every dive begins with Gas 1, and 10 minutes after surfacing from a dive, operation defaults to the Gas 1.
Access to Switching screens can only be accomplished during the time that a Dive Main screen is being displayed and cannot be
performed during the time that an Alarm is sounding.
If a Switch to a new Gas would expose the diver to a prohibitive PO2 level of 1.60 ATA or greater, the Audible will sound during
which a message will be displayed (Fig. 75).
Due to the possibility that sufficient air may not be available in the Switch From tank to complete the dive, the switch to the
prohibitive mix can still be made. If the switch is made to the prohibitive mix, the High PO2 Alarm will activate.
Switching of Gas mixes can only to be performed during the time that a Gas Switch Preview screen is being displayed. These
are accessed from a Dive Main screen.
• M (2 sec), while viewing a Dive Main will access the Gas 1 Switch Preview screen.
• Operation will revert to the Dive Main after 10 seconds of no further M button action.
