Provider.
Actuator Adjustment
The VSI can control optional power accessories such as a power elevating seat using the actuator keys
and the joystick.
NOTE: Actuator adjustment may vary depending on the VSI program. This section describes
basic actuator adjustment for power chairs equipped with one actuator. Contact your Pride/
Quantum Provider for more information regarding actuator adjustment for your power chair.
Follow the steps below for actuator adjustment for power chairs with one actuator:
1. Power on the controller.
2. Press either actuator key to activate actuator adjustment mode. Both actuator LEDs will be lit.
3. Give a forward or reverse command to the joystick to adjust the actuator.
4. Press either actuator key to return to the drive mode.
Sleep Mode
Your VSI controller has a sleep mode feature. Sleep mode is a built-in circuit that automatically shuts
off the main power if the joystick is not moved in any direction for a period of time predetermined by
controller program. The battery condition meter lights on the keypad indicate sleep mode by blinking
once every five seconds. To restore power and continue, push the on/off key twice.
