Ascent Rate; Battery - Suunto EON CORE 2.0 User Manual

Suunto EON Core
Before high-altitude diving, you need to adjust the altitude settings of your dive computer so
that the calculations take into account the high altitude. The maximum partial pressures of
nitrogen allowed by the mathematical model of the dive computer are reduced according to
the lower ambient pressure.
This setting automatically adjusts the decompression calculation according to the given
altitude range. You can find the setting under Dive settings » Parameters » Altitude and
select from three ranges:
0 – 300 m (0 – 980 ft) (default)
•
300 – 1500 m (980 – 4900 ft)
•
1500 – 3000 m (4900 – 9800 ft)
•
As a result, the allowed no decompression stop limits are considerably reduced.
WARNING: SET THE CORRECT ALTITUDE SETTING! When diving at altitudes greater
than 300 m (1000 ft), the altitude setting must be correctly selected in order for the computer
to calculate the decompression status. The dive computer is not intended for use at altitudes
greater than 3000 m (10000 ft). Failure to select the correct altitude setting or diving above
the maximum altitude limit will result in erroneous dive and planning data.

3.4. Ascent rate

During a dive, the bar on the left indicates ascent rate. One bar step corresponds to 2 m (6.6
ft) per minute.
The bar is also color coded:
Green indicates ascent rate is ok, less than 8 m (26.2 ft) per minute
•
Yellow indicates ascent rate is moderately high, 8-10 m (26-33 ft) per minute
•
Red indicates ascent rate is too high, over 10 m (33 ft) per minute
•
When maximum allowed ascent rate is exceeded for five seconds, an alarm is generated.
Ascent rate violations result in longer safety stop times and mandatory safety stops.
WARNING: DO NOT EXCEED THE MAXIMUM ASCENT RATE! Rapid ascents increase the
risk of injury. You should always make the mandatory and recommended safety stops after
you have exceeded the maximum recommended ascent rate. If this mandatory safety stop is
not completed the decompression model will penalize your next dive(s).

3.5. Battery

Suunto EON Core has a rechargeable lithium-ion battery. Charge the battery by connecting
Suunto EON Core to a power source with the included USB cable. As a power source use
your computer USB port.
The battery icon in the upper-left corner of the display shows the battery status. To the right of
the battery icon is the estimated remaining dive time in hours.
