OPERATION
B. Controller Display:
The controller display is a multifunction visual display. It can provide three types of
information: i) ON/OFF status, ii) battery condition meter and iii) fault diagnostics.
1. ON/OFF Status
When the power is on, the controller's LED will be lit up. If the LED is not lit, the controller is
OFF.
2. Battery Condition Meter
The battery condition meter is composed of 6 segments (two each of red, orange, and
green). It enables you to monitor battery charge. The battery condition meter indicates
the approximate amount of battery charge left.
B
Red, orange and green LEDs indicate that the batteries are fully charged.
B
Red and orange LEDs indicate that you should charge the batteries if possible.
B
Red LEDs indicate that you should charge the batteries as soon as possible,
because low battery voltage may cause your power wheelchair to become
inoperative.
Note: When the batteries begin to approach a discharged state, the first red LED will
begin to flash slowly, reminding you that the batteries need to be charged immediately.
3. Diagnostics:
The controller's LEDs can also indicate some common causes of problems with your
power wheelchair. The following chart lists possible problems indicated by the flashing
meter:
