SPECIFICATIONS (CONTINUED)
WARNING: If your dive computer stops working for any reason, it is important that you have anticipated this
possibility and are prepared for it. This is an important reason for not pushing the no decompression and
oxygen exposure limits, and a critical reason to avoid entering decompression.
If you dive in situations where your trip would be ruined or your safety would be jeopardized by losing the
use of your dive computer, a backup instrument system is highly recommended.
