Figure 6.12. Decompression dive, above ceiling. Note a downward pointing arrow, an
Er warning and an audible alarm. You should immediately (within 3 minutes) descend
to or below ceiling.

In addition, an Error warning (Er) reminds you that you have only three (3) minutes to
correct the situation. You must immediately descend to, or below, the ceiling.
If you continue to violate the decompression, the dive computer will go into a permanent
Error Mode. In this mode, the instrument can only be used as a depth gauge and timer.
You must not dive again for at least 48 hours (refer to Section 5.5. Error conditions).
