5.10.3. Battery power indication
Temperature or internal oxidation of the battery affect the battery voltage. If the
instrument 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 batterymay be toolow to operatethe dive computer, andbattery replacement
is recommended.
NOTE
For safety reasons, the backlight cannot be activated when the
low battery warning is indicated by the battery symbol.
The optional wireless pressure transmitter sends out a lowbat (LOBT) warning when
its battery voltage is getting low. This is shown intermittently instead of the pressure
reading (see Section5.3). Whenyou getthis warning,the pressure transmitter'sbattery
needs to be replaced.
