3.1.2. Battery Power Indicator and Low Battery
Warning
This dive computer has a unique graphic Battery Power Indicator designed to give
you an advance notice of impending need to change the battery.
The Battery Power Indicator can always be seen, when the Dive Mode is acti-
vated. The electroluminescent backlight will be on during the battery check. The
following Table and Figure show the various warning levels.
TABLE 3.1 BATTERY POWER INDICATOR
NOTE! Temperature or an internal oxidation of the battery affects the battery
voltage. If the instrument is stored for a long period, the low battery warning
may be displayed even though the battery has enough capacity. The low
battery warning may also be displayed at low temperatures, even though
the battery has enough capacity in warmer conditions. In these cases repeat
the battery check procedure.
In all the other modes 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
the battery replacement is recommended.
NOTE! For safety reasons the backlight can not be activated when the low
battery warning is indicated by the battery symbol.
