WHEN TO CHARGE BATTERIES (FIGURE 6)
MKIV-A AND MKIV-RII
JOYSTICKS
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.
MKIV-A+ JOYSTICKS
The left half of the second line on the LCD is the Battery Discharge Indicator (BDI). It
provides information on the remaining charge in the batteries. At full charge solid blocks
fill in all ten (10) segments between E (Empty) and F (Full). As the battery becomes
discharged, the farthest right segments will progressively disappear a half bar at a time
until no segments appear between E and F. At this level the word RECHARGE will
appear on the second line to indicate that the user should charge the batteries as soon
as possible.
CHARGING BATTERIES (FIGURE 7)
NOTE: New batteries MUST be fully charged prior to initial use of the wheelchair.
WARNING
Never attempt to recharge the batteries by attaching cables directly to the
battery terminals or clamps. Always use the recharging plug located on the
side of the wheelchair frame.
DO NOT attempt to recharge the batteries and operate the power wheelchair
at the same time.
During use and charging, unsealed batteries will vent hydrogen gas which is
explosive in the right concentration with air.
DO NOT sit in wheelchair while charging batteries.
