3.5 Battery indicators
Temperature or internal oxidation can affect the battery voltage. If
you store your Suunto D4f for a long period or use it in cold
temperatures, the low battery warning may appear even though
the battery has enough capacity.
In these cases, re-enter dive mode and check the battery power. If
the battery is low, the Low Battery warning comes on.

recommended.
NOTE: For safety reasons, the backlight and buzzer (sound)
cannot be activated when the low battery warning is displayed.
