[ GAGE mode ]
Only current depth, water temperature and dive time information will appear
on screen. Calculation functions (such as PGT and OLI etc) are not performed. If
you use this mode when diving, it will remain in GAGE mode until 48 hours have
elapsed.
NOTE: When diving in GAGE mode, safe stop will not function.
[ To mark specific depth ]
One can mark out a specific depth in the dive profile if C button is pushed
during a dive. However, it is not possible to use this function while changing to a
different Mix.
