5.9.3. Battery power indication

Temperature or internal oxidation of the battery affect the battery voltage. If the instru- ment is stored for a long period, or used in cold temperatures, the low battery warning may be displayed even though the battery has enough capacity. In these cases, re- enter DIVE mode to receive the battery power indication.

After the battery check, the Low Battery Warning is indicated by the battery symbol.

If the battery symbol is displayed in the Surface mode, or if the display is faded or weak, the battery may be too low to operate the dive computer, and battery replacement is recommended.

NOTE

For safety reasons, the backlight cannot be activated when the

 

low battery warning is indicated by the battery symbol.

5.9.4. Diving at altitude

The dive computer can be adjusted both for diving at altitude and also to increase the conservatism of the mathematical nitrogen model.
