SUUNTO Cobra2 - Manual (Page 41)

CAUTION • Do not use compressed air to blow water off the unit.
• Do not use solvents or other cleaning fluids that might cause
damage.
• Do not test or use the dive computer in pressurized air.
8.4. Water resistance inspection
The water resistance of the unit must be checked after replacing the battery or after other
service operations. The check requires special equipment and training.
You must frequently check the display for any sign of leaks. If you find moisture inside
your dive computer, there is a leak. A leak must be corrected without delay, as moisture
will seriously damage the unit, even beyond repair. Suunto does not take any responsibility
for damage caused by moisture in the dive computer, if the instructions of this manual
have not been carefully followed.
In the event of a leak, immediately take the dive computer to an authorized Suunto
representative.
8.5. Battery replacement
NOTE It is advisable to contact an authorized Suunto representative for
battery replacement. It is imperative that the change is made in a
proper manner to avoid any leakage of water into the battery
compartment or computer.
CAUTION Defects caused by improper battery installation are not covered by
the warranty.
CAUTION When the battery is changed, all nitrogen and oxygen uptake data is
lost. Therefore, the no-fly time shown by the computer should have
reached zero or you must wait for 48 hours, or preferably up to 100
hours, before you dive again.
All history and profile data, as well as the altitude, personal, and alarm settings, will remain
in the dive computer memory after the battery change. However, the clock time and time
alarm settings are lost. In the NITROX Mode, the nitrox settings also revert back to default
settings (MIX1 21 % O

smallest dirt particles may cause a leakage when you dive.
