When to Charge Batteries

SPJ+ Joysticks
NOTE: For this procedure, refer to FIGURE 12.7.
The Information Gauge Display located on the front of the joystick housing, it provides
the state-of-battery charge, including notification of when the battery requires charging.
It also provides the following information to the user on the status of the wheelchair:
A. GREEN LEDs are lit, indicating well
charged batteries.
B. AMBER LEDs are lit, indicating
batteries are moderately charged.
Recharge batteries before taking a
long trip.
C. RED LEDs are lit, indicating
batteries are running out of charge.
Recharge batteries as soon as
possible.
MPJ+ Joystick
NOTE: For this procedure, refer to FIGURE 12.8 on page 117.
The far right side of the screen is the Battery Gauge Display (BGD). It provides
information on the remaining charge in the batteries. At full charge, solid blocks fill in all
ten segments between E (Empty) and F (Full). As the battery becomes discharged, the top
most segments will progressively disappear until no segments appear between E and F.
At this level, the user should charge the batteries as soon as possible.
MKIV-A and MKIV-RII Joysticks
NOTE: For this procedure, refer to FIGURE 12.8 on page 117.
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 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 bars (left) are illuminated. At this level the last two bars (left) will start
to Flash ON and OFF to indicate that the end user should charge the batteries as soon as
possible.
