WHEN TO CHARGE BATTERIES

(FIGURE 3)
It is advantageous to recharge daily rather than only when
necessary. In fact, a battery's life is extended if the charge
level is maintained well above a low condition.
MKIV RII Joystick
BATTERY DISCHARGE INDICATOR (BDI) is located at
the front of the joystick housing and provides information
on the remaining charge in the batteries. At FULL charge
the BDI will be GREEN. As the battery becomes discharged,
the BDI indicator will turn AMBER (YELLOW), then RED
and finally FLASHING RED. If the BDI is FLASHING RED,
the user should charge the batteries as soon as possible.
NOTE: Accurate readings are displayed when in neutral.
MCC-MKIV X, A or A+ Joystick
BATTERY GAUGE DISPLAY (BGD) is the bar graph dis-
play located on the MKIV X, A or A+ 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 illumi-
nated. 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 batter-
ies as soon as possible.
NOTE: Accurate readings are displayed when in neutral.
