Turning Off the Audible Alarm
WARNING: Turning off the audible alarm disables an impor-
tant tool that can help you avoid decompression diving or low
breathing gas emergencies. Although possible, Oceanic does
not recommend the disablement of the audible alarm.
The audible portion of the alarm may not be desired by some divers in
certain situations. Underwater photographers, for instance, may find
that the alarm frightens off marine life at a close distance, and will
therefore want to turn it off temporarily before they begin a dive involv-
ing that activity. For a reason such as this, the audible portion of the
alarm feature may be turned off at your discretion. The DataTrans Plus
will otherwise continue to display information according to the values
that have been entered for the Alarm settings.
