SUUNTO Vyper Air - Manual (Page 99)

5. Carefully remove the lid with the beeper attached to it. You can remove the lid by
pressing with your finger on the outermost edge of the lid while simultaneously
pulling with your nail at the opposite side. Don't use sharp metal objects as they
might damage the O-ring or the sealing surfaces.
6. Remove the O-ring and the battery retainer.
7. Carefully remove the battery. Do not damage the electrical contacts or the sealing
surface.
8. Check for any traces of flooding, particularly between the beeper and the lid, or
for any other damage. In case of a leak or any other damage, bring the dive
computer to an authorized SUUNTO dealer or distributor for check and repair.
9. Check the condition of the O-ring; a defective O-ring may indicate sealing or
other problems. Dispose the old O-ring, even if it seems to be in good condition.
10. Check that the battery compartment, battery holder and lid are clean. Clean with
soft cloth if necessary.
11. Gently insert the new battery in the battery compartment. Check the polarity of
the battery: the “-” mark should point toward the bottom of the compartment and
the “+” mark upwards.
12. Reinstall the battery retainer in its correct position.
13. Check that the new lubricated O-ring is in good condition. Put it in the right position
on the battery compartment lid. Be very careful not to get any dirt on the o-ring
or its sealing surfaces.
14. Carefully press the lid onto the battery compartment with your thumb, while
making sure that the O-ring is not at any point protruding out on the edge.
15. Put your other thumb through the locking ring. Press this thumb firmly against the
lid and release the other one. Make sure that the lid is pressed completely down!
