Replacing the Battery
WARNING: A continuously flashing battery menu cursor alerts you that the
battery is low and should be changed as soon as possible. If there is not
enough power for the gauge to operate correctly, it immediately shuts down
after activation. Since changes in temperature can suddenly shorten battery life,
Aqua Lung advises that you do not dive when the battery cursor is flashing.
Furthermore, Aqua Lung recommends that you install a fresh battery before any
extended, multi-day dive trip.
CAUTION: Damage from improper battery replacement is not covered under the
two year warranty.
To properly change the battery, follow the procedure below:
1. Remove the EPG from the console boot.
2. If there is any sign of moisture, dry the gauge off with a clean towel.
3. Using a coin (never use a screwdriver) turn the battery hatch counterclockwise and
remove it from the case back (figure 15).
4. Using your fingers, press upward on the sides of the O-ring to create a protrusion and
remove the O-ring from the battery hatch and discard (figure 16). Do not use tools to
remove the O-ring.
5. Examine the threads of the battery hatch and case back for signs of damage, which may
impair proper threading. If damage is found, return the EPG to your Aqua Lung dealer.
6. To remove the battery, turn the gauge over and let the battery fall into your hand (figure
17). Discard the battery in a proper receptacle.
