Invacare Pronto M91 User Manual

8 WHEELCHAIR OPERATION
Part No 1143153
53 Invacare® Pronto® M91™
Joystick
The joystick has proportional drive control, meaning that the further the joystick is pushed from the upright (neutral) position, the faster the
wheelchair or seat moves. Your top speed, however, is limited by the programmed settings.
To slow the wheelchair to a stop, simply release the joystick. The wheelchair has automatic speed and direction compensation to minimize
corrections.
Charger/Programming Input
The charger/programming input is located at the front of the joystick housing. This provides easy access for charging the wheelchair batteries. This
port also serves as the Remote Programmer Communication connection. Driving is prevented while the system is charging.
Information Gauge Display
The information gauge display is located on the front of the joystick housing and provides the following information to the user on the status of the
wheelchair:
1. Power is On.
2. True state-of-battery-charge, including notification of when the battery requires charging:
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.
The Information Gauge display also serves as a system diagnostic device when a fault is detected by the control module. A specific number of flashes
of the LEDs indicate the type of fault detected. Refer to Information Gauge Display Diagnostics
on page 113 for the diagnostic indications of the
wheelchair status.
Service Indicator
The AMBER service indicator will light when an error or fault occurs. Refer to Service Indicator Light Diagnostics on page 114 for a listing of the
flash codes and what they indicate.
