Figure 2-16 Low Battery Warning
The "Battery Low!" warning will appear at about 0% battery level. This is a conservative battery level estimation based on normal operation.
If the battery level is low, the battery warning will be displayed after attempting to start a drive/vent cycle (Figure 2-16). The battery icon will also be flashing. Press OK to clear the warning message. It will not be possible to start the vent/ drive cycling with a low battery. Replace the battery or operate the Control Unit manually using the Manual Control Button to continue (see Section 2.7 Manual Drive/Vent Cycles).
