Battery Replacement

The battery is located in a separate battery com-partment on the back side of the instrument (Fig. 6.1.). To change the battery, follow the procedure below:

1.Thoroughly rinse and dry the computer.

2.Open the battery compartment lid by carefully but ﬁrmly turning it counter- clockwise using a coin or a screwdriver. When turned the lid should rise from the compartment. Care should be taken not to damage any of the parts. Use a large enough coin/screwdriver in order not to damage the lid.

3.Remove the battery compartment lid with your ﬁngers. Do not use sharp metal objects as they might damage the O-ring or the sealing surfaces.

4.Carefully remove the battery from underneath the battery retainer/contact. The battery can be removed by inserting a screwdriver under the battery and moving the battery with your ﬁnger. Be careful not to damage the electrical contacts or the sealing surface.

Check for any traces of ﬂooding or 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.

5.Remove the old O-ring from the battery compartment lid.

6.Check the condition of the old O-ring; a defective O-ring may indicate sealing or other problems. Dispose the old O-ring and battery compartment lid, even if they seem to be in good condition.
