You cannot manually turn the TU off. The TU will turn off:
1. After 15 minutes if no tank pressure is sensed and no dive is made.
2. After all 12 half-time compartments are completely "off-gassed"
on repetitive dives.
During an extended surface interval, the TU will enter a "sleep" mode to conserve
battery life. After a dive, your NEMESIS™ IIa NITROX will enter its sleep mode after a
surface interval of 40 minutes. During this sleep mode, all off-gassing calculations
continue and current surface interval and time to fly can be viewed by activating the TU.
Once awakened from its sleep mode, the TU will remain on for one hour before re-
entering the sleep mode. This assumes, of course, that no repetitive dive is initiated
between each wake-up.
The WU is activated by rotating tapping on the lower left corner of the face of the unit for
approximately five seconds or until the display becomes active. Since care has been
taken to reduce the occurrence of the WU being accidentally activated during trans-
port, the WU must be tapped for a longer period of time than is required to manually
activate the TU. This same rotating or tapping action is used to select the alternate
display. The alternate display is shown for three seconds before returning to the
normal display. The optional TACLITE, the active backlighting for the WU display, is
also activated whenever the alternate display is selected. TACLITE will remain illumi-
nated for approximately 10 seconds. If your WU does not have TACLITE, you can
contact your Authorized Dealer for an upgrade.
Since all diving calculations are made by the TU, it is possible to activate the WU
underwater should you mistakenly forget to do so prior to the dive. Once activated, the
WU will immediately display the current diving data being calculated by your TU.
During the dive, it is not possible to turn the WU off.
Once back on the surface, you can manually turn the WU off. This is recommended as
a battery saving measure since all calculations are being performed by the TU. To turn
the WU off on the surface, continuously tap the WU, in the same manner as that used
to activate the unit, until the display goes blank. With a little practice, you will be able to
tell just how many of your "taps" are required to turn the WU off.
