ALL
audible and visual alarms and attention messages are
turned off. This includes ascent speed, low tank pressure and interrupted
signal from transmitter.
In gauge mode TEC will display depth, dive time and tank pressure, the maximum depth is stored, ascent
rate and tank pressure are monitored. By pressing
you can switch from maximum depth to tempe-
rature and vice versa. You can also activate the stopwatch and check the split time. Gauge mode does not
support the calculation of no-stop time or the supervision of decompression. Supervision of ppO
2
max and
CNS O
2
% will also be switched off. TEC will display no information about RBT or microbubble develop-
ment. Bookmarks can be set. The settings for gas mixtures, MOD and microbubble level cannot be set and
the dive planner cannot be selected.
• Dives in gauge mode are performed at your own risk!
• After diving in gauge mode you should wait for at least 48 hours before
using a decompression computer.
Switching the gauge mode on and off
Gauge mode can be switched on and off at the surface, if no desaturation time
is being prescribed.
After diving in gauge mode, TEC can not be used as dive computer for 48
hours.
Procedure:

Diving in gauge mode
After immersion, starting at a depth of about 0.8m (3 ft), TEC automatically sel-
ects gas mixture 1.
The following information is displayed in gauge mode:
Changing the gas mixtures in gauge mode
In gauge mode it is up to the diver to decide on a time and depth to change
the gas mixture. TEC will not indicate a necessary change of gas mixture. For
