Suunto Vyper Air — how to Set Depth, Time Alarms and Nitrox on Diving Computers [21/65]

Превью страниц Страница 21 / 65

NOTE

Some settings cannot be changed until 5 minutes has elapsed after

the dive.

5.8.1. Setting the depth alarm

You can set a depth alarm in the dive computer.

ADJUST WITH UP AND

DOWN BUTTONS. ACCEPT

WITH SELECT BUTTON.

The depth alarm is factory-set to 30 m/100 ft, but you can adjust it according to your

personal preference, or switch it off altogether. The depth range can be set from 3 m to

100 m/9 ft to 328 ft.

5.8.2. Setting the dive-time alarm

The Suunto Vyper

AIR

has a dive-time alarm setting which, when activated, can be used

for several purposes to add to your diving safety.

ADJUST WITH UP AND

DOWN BUTTONS. ACCEPT

WITH SELECT BUTTON.

NOTE

With a range of 1 - 999 minutes, the alarm can be set to your planned

bottom time, for example.

5.8.3. Setting the nitrox values

If set to the NITROX mode, the correct oxygen percentage of the gas in your cylinder (and

additional gases) must always be entered into the computer to ensure correct nitrogen

and oxygen calculations. In addition, the oxygen partial pressure limit must be set.When

in the NITROX setting mode, the equivalent allowed maximum depth, based on the chosen

setting, will also be displayed.

Settings for an additional mix (MIX2) are made similarly, but with the additional selection

of “ON” or “OFF”.

In order to minimize the risk of error during a dive, it is highly recommended that the mixes

are set in the proper order. This means that as the mix number rises, so does oxygen

content, and this is the order they are usually used during the dive. Before a dive, only set

to “ON” the mixes you actually have available and remember to check the set values to

make sure they are correct.

The default oxygen percentage (O

%) setting is 21% (air) and oxygen partial pressure

(PO

) setting 1.4 bar.

After entering values for MIX1, you can enable/disable and set an additional gas mix -

MIX2.
