SUUNTO D6I - Manual (Page 58)

To view the most pessimistic ascent schedule, that is, a schedule for the situation in
which the gases are not changed at all, you can set the mix gas(es) as Secondary
gas, and the time it takes to finish the decompression using the current breathing gas
is shown as the ASC time. Note however, that showing the most pessimistic ascent
schedule during a long dive can easily result in the ascent time no longer fitting the
reserved field and the dive computer displays "---" (max. 199 min).
