3  SOS mode
Activation: automatic
If the diver remains above a depth of 0.8m (3 feet) for more than three minutes
without observing a prescribed decompression, the computer will automatically
switch into SOS mode after the dive.
The display shows the "SOS" sign and the remaining length of the SOS mode. 
The dive will be entered in the logbook with "SOS". Other than that the SOS 
mode has no further impact on the displays and functions on the surface.
• Serious injury or death may result if a diver does 
not seek immediate treatment should any signs 
or  symptoms  of  decompression  sickness  occur 
after a dive.
• Do not dive to treat symptoms of decompression sickness! 
• Diving  in  SOS  mode  is  extremely  dangerous  and  you  must  assume  full 
responsibility for such behaviour. UWATEC will assume no liability. 
Once in the SOS mode, the computer will lock up and will be inoperable as a 
diving instrument for 24 hours. 
A diving accident can be analyzed at any time in the logbook and downloaded 
to a PC by means of the infrared interface (IrDA) and the SmartTRAK software.
