9.3. Replacing the battery
The battery and the buzzer are located in the back of the instrument in a separate
compartment. To change the battery:
1.
Unscrew the four screws at the back of the elastomer console and remove the
back cover of the console.
2. Thoroughly rinse and dry the computer.
3. Open the securing ring of the battery compartment lid by pushing it down and
rotating it clockwise. You may use a pointed nose pliers or a small screwdriver
as an aid in the rotating. Put the pliers ends into the holes of the securing ring or
the screwdriver onto the side of the right tooth on the ring and turn the ring
clockwise. Be careful not to damage any of the parts.
4. Remove the ring.
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.
