Body metabolism varies from person to person, and even from day to day. If
you are feeling less than 100%, or you are in less than perfect physical shape,
use the caution (C.Z.) zone as a visual reference to place a wider mar-
gin of protection between you and the limits of oxygen tolerance.
MESSAGE BOX WARNINGS
When diving beyond the normal limits of recreational sport diving, it is pos-
sible that you will violate more than one condition at a time, such as exceeding
the maximum recommended ascent rate, ascending above a required ceiling
stop depth, or exceeding the maximum allowed partial pressure of oxygen. In
these situations, the Message Box will display the most important warning for
that time, allowing more critical warnings to override others of lesser impor-
tance (Fig. 106).
UNEXPECTED LOSS OF DISPLAYED INFORMATION
While No Decompression diving, if you find that any major piece of
equipment is not functioning correctly, you must abort the dive im-
mediately and surface slowly in a controlled manner. If your
DataTrans Plus stops working for any reason, it is important that you have
anticipated this possibility and are prepared for it. This is an important
reason to avoid pushing the no decompression and oxygen tolerance
