BATTERIES PROCEDURE 11

WHEN TO CHARGE BATTERIES (FIGURE 7)

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 theBDIwillbeGREEN.Asthebatterybecomesdischarged, 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.

CHARGING BATTERIES (FIGURE 8)

WARNING

Never attempt to recharge the batteries by at- taching cables directly to the battery terminals or clamps. Always use the recharging plug lo- cated on the controller OR the side/rear 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.

CAUTION

Always charge new batteries fully BEFORE initial use or battery life will be reduced.
