E. JOYSTICK ASSEMBLY

The joystick connects to a controller, which controls
the chair’s performance. The joystick assembly consists
of the following parts:

1. Speed Control Knob (D):

Use the speed control knob to adjust the maximum
speed of your chair. Turn it counter-clockwise to reduce
speed; turn it clockwise to increase speed.

2. Battery Charge Indicator (B):

•

Green lights indicate that batteries are fully
charged.

•

Yellow lights indicate that batteries need
recharging.

•

When the lights stay in the red band, the bat-
teries must be recharged.

3. On/Off Mode Switch (A)

The on/off mode switch is located on the rear face
of the joystick housing. It is a toggle switch.
Turning the chair on or off, is accomplished by
pressing the switch downward. The switch will
automatically return to the center point. Alternate
locations exist for this switch. Please see your
supplier in the event that you wish to relocate or
re-orient this switch.

4. Mode Switch (A)

The on/off mode switch allows you to select from 5 (five)
different programmable drive profiles or actuator mode sets.

•

Push up the on/off mode select toggle switch
to index among the five drive and actuator
modes. The selected mode indicator will flash.

•

Push joystick either left or right to select one
of the five drive profiles. To select the actuator
modes, push the mode select switch twice.

•

The drive profiles are indicated by the mode
indicators (G) and the actuators are indicated
by the four actuator lights (H).

•

To exit drive or actuator mode select, simply
push the on/off/mode toggle up one or more
times until the indicator no longer flashes, or
from the mode select, push the joystick forward
or reverse to begin driving.

2. To Program Your Chair:

a. Turn off power to the chair.
b. Insert QTRONIX Programmer plug (A) into the

charger/programmer socket on the front of the
joystick.

c. Turn on power to the chair; program as needed.
d. Remove plug and cycle ON/OFF switch to drive

chair.

NOTE– Review the Qtronix Programmer Owner’s Manual

for more details on how to program your chair.

NOTE– Program settings that are not matched for the

capabilities of the rider can result in serious
injury. Do not alter settings without the advice
of your health care professional.

C. THERMAL ROLL-BACK

Your chair has a thermal roll-back circuit. This protects
the controller from damage due to overheating. In
extreme conditions (such as repetitive hill climbing)
the circuit will decrease the power to your motors. This
allows the chair to operate at a reduced speed. When
the controller cools, the chair will return to normal
speed.

D. CIRCUIT BREAKERS

1. Notes:

Your Quickie S-646/S-646 SE has a battery box with a
circuit breaker.

•

In the unlikely event of a short circuit or heavy
overload, all power to your chair will be shut
off.

•

To reset your chair, depress the circuit breaker
button (B) on the front right side of the battery
box. A few minutes wait is required before the
circuit breaker will reset.

2. Repeated Shutdown:

If the chair continues to shut down after resetting,
have it serviced by a supplier.
