Figure 32. VSI Controller Keypad
VII. OPERATION
Keypad
The keypad is located in front of the joystick. It contains
keys necessary to operate your power chair. See figure 32.
On/Off Key
The on/off key turns the VSI on and off.
WARNING! Unless faced with an
emergency situation, do not use the
on/off key to stop the power chair.
This will cause the power chair to
stop abruptly.
WARNING! Always turn the power
off when you are stationary to pre-
vent unexpected movement.
Battery Condition Meter
The battery condition meter is a 10-segment illuminated
display located in front of the joystick. It consists of red,
yellow, and green lights. When the lights are on, it indicates
that there is power to the VSI. The lights also indicate
battery status, VSI operational status, and electrical system
status.
! Red, yellow, and green lights lit: Batteries charged;
VSI operational, and electrical system OK.
! Red and yellow lights lit: Charge batteries if possible; VSI operational, and electrical system OK.
! Red lights only lit or slow flash: Charge batteries as soon as possible; VSI operational, and electrical system OK.
NOTE: When the batteries approach a discharged state, the first red light will begin to slowly flash, reminding
you the batteries need to be charged immediately!
! Rapid flash of lights: Indicates a fault in the VSI or the electrical system. Refer to “VSI Error Codes.”
! Ripple side to side of lights: The joystick was not in the neutral position when the controller was turned on. If you
get “ripple side to side of lights,” turn off the controller, allow the joystick to return to the neutral position, then turn on
the controller.
NOTE: If you still get “ripple side to side of lights,” contact your Quantum Rehab Specialist.
Speed/Profile Keys
The speed/profile keys control either the speed setting or the drive profile. Press the speed/profile increase key to increase
the speed setting or change the drive profile to a higher number. Press the speed/profile decrease key to decrease the
speed setting or change the drive profile to a lower number. The speed setting or drive profile is displayed on the maximum
speed/profile indicator. If your power chair was programmed with a drive profile, contact your Quantum Rehab Specialist
for more information.
NOTE: We recommend that the first few times you operate your power chair, you use the lowest speed setting
until you become familiar with your new power chair.
