Environmental conditions
Store the OSTC3 in a cool, dry place.
Permissible temperature range for use
and storage: between -5 °C and 40 °C.
Make sure that the used battery is
suitable for the ambient temperature to
be expected in your dives. For cold water
diving (under 10°C) we recommend the
use of a Lithium battery.
Note
Decompression calculations and depth
display are always based on the actual
surface pressure. So if you are diving in
mountain lakes , no further settings are
needed. OSTC3 automatically adapts to
the actual surface pressure.
