Battery Saver Feature
When the battery capacity drops to below 21V (typically two LEDs), the controller reduces wheelchair perfor-
mance to conserve battery power.
Out Of Neutral At Power Up
Your Jazzy joystick is equipped with Out Of Neutral At Power Up (OONAPU). If you power up the system and
the joystick is
not
in the neutral position, the System Status Indicator flashes rapidly for either as long as the
joystick is out of the neutral position or for five seconds. If this happens and all the segments on the system status
indicator flash, you may have set trouble code 1.
Actuator Keys with LEDs
These keys can control up to five actuators independently. You can control them through either of the two actuator
keys or you may select the actuator through drive program mode 0. These actuators may be power elevating seats,
tilt-in-space seats, power reclining seats, indicator lights, or headlights and taillights.
To control actuator movement with either of the two actuator keys:
1. Press the actuator key to activate the actuator.
2. Move the joystick beyond half its travel in either the forward or reverse direction to move the actuator.
To use the joystick to control the actuators:
1. Press the Drive Mode Select key until you get to 0.
2. Move the joystick to either the left or right turning position to scroll through the options which are A, b, C, d,
or E.
3. Select an option.
4. Move the joystick beyond half its travel in either the forward or reverse direction to move the actuator.
Sleep Mode
The Jazzy controller features a sleep mode, which is a built-in circuit that automatically shuts off the main power if
the joystick is not moved in any direction for a specific amount of time. This time factor is programmed into your
joystick console. The battery condition lights on the joystick indicate sleep mode by blinking once every five
seconds. To restore power and continue, push the on/off key twice.
Thermal Rollback
Jazzy controllers are equipped with a thermal rollback circuit. This circuit monitors the temperature of the motors
and controller. In the event the motors or controller become excessively hot (above 122° F), the controller reduces
the motor voltage. For every degree above 122° F, the controller reduces the voltage by 5 volts. This reduces your
speed and allows the components to cool down. When the temperature returns to a safe level, your Jazzy resumes
its normal speed.
