8. 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.
9. Check that the battery compartment, battery holder and lid are clean.
Clean with soft cloth if necessary.
10. 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.
11. Reinstall the battery retainer in its correct position.
12. Check that the new lubricated O-ring is in good condition. Put it in
the right position on the battery compartment. Be very careful not to
get any dirt on the o-ring or its sealing surfaces.
13. Carefully press the lid onto the battery compartment with your thumb.
It is better to press down the lid down one side fi rst, this minimizes
entrapped air and it is thus easier to hold down the lid. Make sure
that the O-ring is not at any point protruding out on the edge.
14. Put your other thumb through the locking ring. Press this thumb
fi rmly against the lid and release the other one. Make sure that the
lid is pressed completely down!
15. Turn the locking ring counterclockwise with your free thumb and
fi ngers until it snaps into its locked position.
16. The dive computer should now active it’s timekeeping mode and
show time 18:00 [6:00 PM] and date SA 01,01. Activate the instru-
ment. Check that:
• All display segments work.
• The low battery warning is off.
• The buzzer beeps and backlight works.
• All the settings are correct. Reset if necessary.
17. Install the dive computer back into the console or boot and reas-
semble the strap. The instrument is now ready for use.
Wrist model:
• Assembling into the boot: First insert the longer strap in its hole in
the front of the boot and then the dive computer into its cavity in the
boot starting at the back end. Then snap also the long strap end of
the instrument into the boot. Stretch the boot as needed.
