6. When finished, press Select to advance to the next option (dive
time alarm). To exit, press and hold Mode for 1 to 2 seconds to

Setting the dive time alarm
The NiTek Trio has a dive time alarm that is activated when the diver
reaches the dive time that is set for the dive. When the dive time is
reached, an audible alarm sounds and the screen flashes for three
seconds. Dive time alarm can be used when you want to set a
maximum dive time for your dive. The alarm indicates when this time
has expired.
The alarm can be turned on or off and can be set from 1 to 599 minutes.
To set the dive time alarm:
1. Repeatedly press Mode until “DIVESET” is displayed on the
screen.
2. Repeatedly press Select until the screen changes and “DIVETIME
ALARM” is displayed.
The dive time is flashing.
3. Press Set to set the time when you want the alarm to sound.
4. Press Select.
The dive time alarm “ON/OFF” flashes.
5. Press Set to toggle the alarm on and off.
6. When finished, press Select to advance to the next option
(deepstop). To exit, press and hold Mode for 1 to 2 seconds to
return to time mode.
Setting the deepstop option
The NiTek Trio has the ability to include deep stops into its
decompression algorithm, and they are available for dive-depths deeper
than 65 ft (21m). Deep-stops are only available on dives that are
actually a decompression dive, as recreational dives do not give deep-
stop information. When activated, deep stops will recommend an
additional stop (similar to a safety-stop) at its deepest stop at the
highest safety-factor level. The deep stop is highly recommended as
additional opportunity to off-gas, but is not mandatory. If the diver
chooses not to observe a deep-stop, it will not add to the shallower
deco-stops.
To set the deep-stop:
1. Repeatedly press Mode until “DIVESET” is displayed at the top of
the screen.
