4.6 Using the Battery
The battery level indicator with a residual quantity is shown on
the left side of the Control panel. When the battery indicator
has one flickering light (level 1), charge the battery
immediately. The figure below shows each battery indicator
from level 1 to 3
Level 3 Level 2 Level 1
When the battery reaches Level 1, charge the battery at least
for an hour to avoid a low voltage. All displays are turned off
under the low voltage except for the error code A.10, as
shown (see the figure below).
After the device is connected to the battery charger and the
battery level becomes ‘Level 1’, all functions are returned to
normal operation.
