NiBG Alarm
While operating in FREE Dive mode, residual Nitrogen remaining from the FREE Dives and any previous NORM Scuba Dives
conducted within 24 hours is displayed as the NiBG.
When Nitrogen loading increases to the Caution level, 3 short beeps will sound 3 times; and 4 NiBG No Deco segments, the Up
Arrow icon, and the graphic NBG (in place of NDC) will be displayed (flashing) (Fig. 100).
After the beeps, the flashing will continue until the NiBG recedes to 3 segments at which time the NDC will be restored and the
Up Arrow icon will be removed. In the event that Nitrogen loading increases to the Deco level, operation will enter Violation
Gauge Mode for 24 hours.
Entry into Deco (Violation)
Upon entry into Deco, 3 short beeps will sound 3 times, during which the full NiBG, graphic VIO, and Up Arrow icon will flash
(Fig. 101).
Upon surfacing, the Up Arrow icon will be removed, then after 10 minutes the NiBG will be removed. The graphic VIO will then
alternate with FRE for 24 hours during which dive computer operation will lock into Violation Gauge Mode with access to Watch
Mode allowed. Access to NORM or GAUG will be blocked.
ADDITIONAL INFORMATION PERTAINING TO FREE DIVE MODE
Although breathing apparatus is not utilized for FREE Dive activities, nitrogen tissue loading remains a factor. Nitrogen loading is calculated based
upon a fixed FO2 of AIR. Since a user has the option of alternating between NORM (SCUBA) and FREE Dive activities within a 24 hour period, ni-
trogen calculations and the displayed value of NDC Time are carried over from one operating mode to the other, which permits the user to maintain
awareness of nitrogen absorption and off gasing status.
The mathematical model currently used in the Talis is based on no decompression/decompression multilevel repetitive dive schedules. This algorithm
does not take into account the physiological changes associated with the high pressures that competitive type Free diving can expose a diver to.
WARNINGS:
• Ensure that you know which Operating Mode is selected (NORM, GAUG, or FREE) prior to commencing any dive.
• Conducting Free dives within a 24 hour period after conducting SCUBA dives, combined with the effects of multiple
rapid Free Dive ascents, increases your risk of decompression sickness. Such activities may result in accelerated
entry into decompression which could cause serious injury or death.
• Combining competitive type Free dive activities that involve multiple descents/ascents with activities utilizing SCUBA
during the same 24 hour period is not recommended. Presently, there is no data relating to such activities.
• It is highly recommended that anyone planning to become involved in competitive type Free dive activities obtain
proper instruction and training from a recognized Free Diving trainer. It is imperative that the physiological affects
be understood and the diver is physically prepared.
