SECTION 8
WHEN TO CHARGE BATTERIES (FIGURE 9)
The Battery Discharge Indicator (BDI) is a bar graph display located on the MKIV joystick. It
will keep you informed as to power availability. A visual warning is given before the power
becomes too low to operate the wheelchair. At full charge the two (2) LEFT segments and
the farthest RIGHT segment of the bar graph will be illuminated. As the battery becomes
discharged, the farthest RIGHT segment will progressively move to the LEFT until only the
last two (2) bars (LEFT) are illuminated. At this level the last two (2) bars (LEFT) will start to
Flash ON and OFF to indicate that the end user should charge the batteries as soon as
possible.
