WARNING: Properly replacing the batteries from the TU will not cause your dive
computer to lose current nitrogen absorption and elimination data for the most
recent dive or dive series. See the section regarding BATTERY REPLACEMENT
in this manual.
Gauge Mode Alarm:
You will hear your dive computer sound its five-chirp alarm just prior to entering the
Gauge Mode. It will re-issue its five-chirp alarm if the TU is powered up within 24
hours after entering Gauge Mode.
Your computer will enter the Gauge Mode if:
more than five minutes has elapsed with the depth less than the ceiling
or
a ceiling depth of 90 feet or greater is required
or
the maximum functional operating depth of 327 feet is exceeded.
Two-Minute Warning:
Should you have less than two minutes of remaining no-decompression time, your
dive computer will:
issue a one time, five-chirp audible warning
and
flash the WARNING legend on the WU.
60 Foot Decompression Stop Warning:
Should you require a decompression stop greater than 60 feet, the unit will issue a one
time five-chirp audible warning.
Entering Emergency Decompression Mode:
Should you enter Emergency Decompression Mode, the TU will issue a one time five-
chirp audible alarm.
Oxygen Tolerance Units (OTU) Dose Warning:
Should you reach 75 percent of the allowable Mission OTU dosage, your dive com-
puter will issue a one-time audible warning consisting of short, double-beeps that
sound for five seconds. The WARNING legend will appear and flash and the
TEMPerature digits will be replaced with the current calculated OTU toxicity percent-
age. This visual warning will continue until the calculated toxicity percentage is less
than 75 percent.
Central Nervous System (CNS) Oxygen Toxicity Warning:
Should you reach 75 percent of the associated maximum limit, your dive computer will
issue a one-time audible warning consisting of short, double-beeps that sound for five
seconds. The WARNING legend will appear and flash and the TEMPerature digits will
be replaced with the current calculated CNS Oxygen Toxicity percentage. This visual
warning will continue until the calculated toxicity percentage is less than 75 percent.
