Off-board Charger/Programming Socket
You may use an off-board charger to charge the Z-Chair batteries through the 3-pin socket located on the front of the VSI.
If you use an off-board charger, the charger current should not exceed 8 amps. Contact an authorized Pride Provider for
more information.
WARNING! Only chargers with Neutrik NC3MX plugs should be connected to the off-board charger/
programming socket. See an authorized Pride Provider for more information.
NOTE: The socket may also be used for reprogramming the VSI. Contact an authorized Pride Provider for
more information.
NOTE: The off-board charger/programming socket on the controller should be used when charging the bat-
teries with the battery box installed on the power base.
Controller Connector
This connects the VSI to the travel chair’s batteries, motors, and motor brakes.
Sleep Mode
The VSI controller is equipped with 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 preset period of time. 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.
