Safety stop indication
The NiTek Plus has an automatic three-minute safety stop
feature built in. On any dive, when you descend below 33 feet
(10 meters) and then ascend above 20 feet (6 meters), “safety
stop” is displayed and the NDL changes to a three-minute
countdown.
During this time, if you ascend above 10 feet (3 meters), the
countdown pauses. It resumes when you descend back below 10
feet (3 meters). If you descend below 20 feet (6 meters) during
this time, “safety stop” and the three-minute countdown
disappear; the NDL readings reappear. When you again ascend
above 20 feet (6 meters), the three-minute countdown restarts.
